Common Canine Poisons and Toxins
There are hundreds of items your dog can get access to. Some things are highly toxic and others are non-toxic. This article is a guide to help you determine if a particular item is a problem and provide you with the information you need to best help your pet.
If you think your dog may have been exposed to a toxin, the best thing to do is to check the label of the item you think your pet ingested. Read the information about toxicity. Often, but not always, the information on packaging regarding children is relevant to dogs and some manufacturers even discuss dog toxicity. If there is an 800 number on the package - call them! It's also recommended that you call your veterinarian to confirm the recommendations. If you go to your veterinarian, take all packaging and any information you have on the product.
General Information. For most poisonings, there is not much you can do at home. Consult your veterinarian or veterinary emergency facility if you suspect your pet has been poisoned. For some ingested poisons, your veterinarian may recommend inducing vomiting before bringing the pet in for examination and treatment. Inducing vomiting of a toxic substance should never be done unless specifically directed by a veterinarian. For topical exposures, bathing in lukewarm water with a mild dish soap can reduce further toxin absorption before the pet is examined and treated by a veterinarian.
List of Common Dog Toxins
Non-toxic Items Commonly Eaten by Dogs. Chewing on things is a normal part of puppyhood so before you rush your pooch to the veterinarian, here is a list of some commonly eaten and, thankfully, non-toxic items. If your pup chews any of these, don't worry about toxicity. The only real concern is the potential for obstruction if the object or container becomes lodged in the stomach or intestines. Also, you can expect some vomiting and maybe even a little diarrhea from eating a non-food item.
Amitraz. Amitraz is an insecticide used in some brands of dog tick collars and topical solutions. Toxicity most often affects curious puppies who ingest the poison but can occur from wearing the tick collar or receiving demodectic mange treatment. Typical symptoms begin within about 2 to 6 hours of ingestion and often begin with the pet becoming weak and lethargic. Vomiting, diarrhea and disorientation are also common. Without treatment, coma may result. In severe untreated cases, toxicity may result in death. Call and see your veterinarian for treatment.
Amphetamines. Amphetamines are human medications that are commonly used as appetite suppressants and mood elevators or for the treatment of attention deficit and hyperactivity disorders. Amphetamines must be prescribed by a physician, but because they are popular as appetite suppressants and mood elevators, they are often purchased illegally. Amphetamines are nervous system stimulants that also affect the brain. After ingestion, toxic signs are usually seen within one to two hours. Common signs include restlessness, hyperactivity, agitation, tremors and seizures. Prompt veterinary treatment for amphetamine toxicity is crucial and will give your pet a better chance of full recovery. If left untreated, amphetamine toxicity can be fatal.
Ant Traps. If an ant trap is ingested, the only real concern is the potential for obstruction if the object or container becomes lodged in the stomach or intestines. Most ant and roach traps are made from either sticky paper or chlorpyrifos, which has a low level of toxicity in mammals but is highly toxic to insects. Also, you can expect some vomiting and maybe even a little diarrhea from eating a non-food item.
Antifreeze. Ethylene glycol toxicosis is a type of poisoning that occurs after ingestion of antifreeze or other fluids containing the ingredient ethylene glycol. Ethylene glycol itself is not toxic, but it is metabolized in the animal's body to several extremely toxic chemicals that are responsible for its potentially lethal effects. Ethylene glycol poisoning results in nervous system abnormalities and severe kidney failure with almost complete cessation of urine output. Ethylene glycol poisoning can be fatal if not treated soon after ingestion (within 4 to 8 hours). The minimum lethal dose for dogs averages five milliliters per kilogram of body weight. Thus, a little more than three tablespoons (or 45 milliliters) could be lethal for a 22 pound (10 kg) dog. Definitive treatment should be started as soon as possible after consumption of ethylene glycol (within a few hours). If treated promptly and appropriately, pets that have consumed ethylene glycol will not develop kidney failure and have a good chance of survival. Signs to watch for include: nausea, vomiting, increased thirst, lethargy and incoordination progressing to coma. Pets may act as if they are intoxicated. These signs develop within 30 minutes to 12 hours after ingestion of ethylene glycol depending on the amount ingested.
Aspirin. Aspirin toxicity (salicylate toxicity) is poisoning that occurs following the ingestion of aspirin or aspirin-containing products. Cats and young animals are more susceptible to the effects of aspirin than are dogs because they are unable to metabolize the drug as quickly. Aspirin interferes with platelets, which are responsible for helping the blood to clot. Disruption of platelet function increases the amount of time it takes the blood to clot after being cut. Spontaneous bleeding may also occur causing pinpoint bruises to appear in the skin and on the gums (petechiae). Aspirin toxicity may cause gastrointestinal problems, respiratory difficulties, neurological problems, bleeding disorders and kidney failure. Gastrointestinal problems are common in dogs whereas central nervous system depression is most common in cats.
Arsenic. Although a common poison in the days of Agatha Christie, arsenic is somewhat difficult to obtain and animal poisonings are rare. Usually, poisoning is due to the ingestion of very old insect traps. Since 1989, the use of arsenic in insect traps has greatly diminished but there are still some out there. The lethal dose is 1 to 25 mg per kilogram of weight, and signs of poisoning include severe vomiting, diarrhea and nausea. If caught early, most pets are treated and recover. If treatment is delayed and the signs of illness are severe, pets usually do not survive. If your pet has ingested an insect trap, make sure to check the label to see if arsenic is present and call your veterinarian.
Bathroom Cleaners, Bleach, Lysol and Other Corrosives. Household cleaners can cause very serious “chemical burns.” Most often these chemicals are ingested or licked by dogs causing a caustic or corrosive burn usually affecting the tongue and upper esophagus. If chemical ingestion is witnessed, immediately flush the mouth with large amounts of water. This can help reduce the amount of chemical in the mouth and may reduce the damage. Chemical oral burns may not show up immediately. Call your veterinarian for additional treatment recommendations. Common signs include: lack of appetite, drooling, pawing at the mouth and excessive swallowing.
Carbon Monoxide. Carbon monoxide is an odorless, colorless gas, that when absorbed into the bloodstream, forms a compound that causes hypoxia (reduced oxygen supply) of the heart and brain. Dogs can be exposed by automotive exhaust in a closed garage, faulty exhaust system, non-vented furnace, gas water heater, gas/kerosene space heater and/or smoke inhalation from a fire. Some pets are predisposed to toxicity due to preexisting heart or lung disease. Symptoms of toxicity include drowsiness, lethargy, weakness, incoordination, bright red color to the skin and gums, difficulty breathing, coma and/or abrupt death. Occasionally, chronic (low-grade, long-term) exposure may cause exercise intolerance, changes in gait (walking) and disturbances of normal reflexes. Be aware that if the source of poisoning still exists, both you and your dog are at risk. Prevent toxicity by minimizing exposure and using carbon monoxide detectors around your home.
Carbamate Insecticides. Carbamates are a type of insecticides used to treat insects on our crops and soils, prevent and treat flea infestations and are used in ant and roach baits. The majority of toxicities in dogs related to this chemical are due to improper use of the chemical, especially when many different types of insecticides are used at the same time. The dog formula should never be used on cats. Carbamates affect the nerve-muscle junctions. Without a normal nerve impulse through the muscle, the function of the muscle is impaired. Since muscle tissue is present in the intestinal tract as well as the heart and skeleton, various signs may be seen if a pet is exposed to toxic levels of this insecticide. Symptoms include: vomiting, diarrhea, drooling, difficulty breathing, muscles tremors, twitching, weakness and paralysis. Prompt veterinary care is required to survive a toxic exposure.
Chocolate. Chocolate, in addition to having a high fat content, contains caffeine and theobromine. These two compounds are nervous system stimulants and can be toxic to your dog in high amounts. The levels of caffeine and theobromine vary between different types of chocolate. For example, white chocolate has the lowest concentration of stimulants and baking chocolate or cacao beans have the highest concentration. Depending on the type of chocolate ingested and the amount eaten, various problems can occur. The high fat content in chocolate may result in vomiting and possibly diarrhea. Once toxic levels are eaten, the stimulant effect becomes apparent. You may notice restlessness, hyperactivity, muscle twitching, increased urination and possibly excessive panting. Heart rate and blood pressure levels may also be increased. Seizure activity may occur in severe cases.
Cocaine. Cocaine is rapidly absorbed from the stomach, nasal passages and lungs. Following exposure the cocaine usually leaves the system within four to six hours. The lethal dose of cocaine in dogs is 25 mg per pound of body weight. Dogs exposed to cocaine show signs of intermittent hyperactivity followed by profound lethargy. Some may develop seizures. Treatment is aimed at supporting the body systems. Inducing vomiting is not helpful since cocaine is so rapidly absorbed. Hospitalization with intravenous fluids and sedatives are typical treatments. Depending on the severity of illness, amount ingested and time lapsed before treatment, some pets exposed to cocaine do not survive.
Detergents and Soaps. Most soaps and detergents are generally non-toxic. You can expect some vomiting and maybe even a little diarrhea from eating a non-food item. Read the container for additional information. If ingestion is witnessed, you may flush the mouth with large amounts of water.
Ecstasy. Ecstasy, also known by various street names such as XTC, Adam and MDA, is chemically related to other amphetamines, which stimulate the central nervous system. After ingestion by dogs, signs of toxicity generally develop within one to two hours and last longer in pets than in humans due to the animal's inability to metabolize the drug. Symptoms include hyperactivity, restlessness, drooling, tremors, staggering, seizures, and if no treatment is given, coma and death ensue.
Estrogen Toxicity. Estrogen toxicity is a condition in which a group of estrogen compounds (female hormones), either produced in excess within the body or administered from the outside, become poisonous to the body of dogs. Estrogen toxicity is seen most commonly in reproductive-age females and older. Symptoms can include: lethargy, pale gums, bleeding, fever, thin hair coat and feminization (female sex characteristics) in males.
Ethanol. Ethanol is an alcohol that is used commonly as a solvent (liquid that dissolves) in medications and is the major ingredient of alcoholic beverages. Common causes of toxicity in dogs include direct access to alcoholic beverages or spilled medication, ingestion of fermented products (bread), intentional or malicious administration by human beings and/or dermal (skin) exposure to these products. Toxicity can cause a wide variety of signs and may lead to death. Signs can include: odor of alcohol on the animal's breath or stomach contents, incoordination, staggering, behavioral change, excitement or depression, excessive urination and/or urinary incontinence, slow respiratory rate, cardiac arrest and death. If you suspect your pet has ingested a form of ethanol, please call your veterinarian for additional instructions.
Fuel. Gasoline is not a commonly ingested toxin, most likely due to its odor. If ingested, unleaded gasoline irritates the gastrointestinal tract and may cause vomiting. Some dogs may inhale stomach contents as they vomit, resulting in aspiration pneumonia. To develop signs of toxicity, the amount of gasoline that needs to be ingested is around 20 ml per kilogram of weight. For a 20 pound dog, that is about 1/2 cup. Diesel fuel and jet fuel may also cause gastrointestinal upset but have less toxicity than unleaded gasoline.
Glow Jewelry. The active ingredient in most glow jewelry and other glow-in-the-dark products is dibutyl phthalate. This substance has low toxicity and there has not been a report of an animal poisoned by its ingestion. If your dog has ingested dibutyl phthalate, you may see profuse drooling. Encourage him to drink a small amount of milk or eat a piece of bread. This will help dilute the taste of the dibutyl phthalate. Even rinsing the mouth out with water can help reduce the signs associated with glow jewelry exposure. Even after rinsing the mouth, you may want to bathe your pet to remove any dibutyl that may have leaked out of the tooth marks and onto the pet's hair coat.
Grape and Raisins. Ingestion of grapes or raisins can be toxic to dogs. The amount of grapes or raisins ingested has been between a few grams to about 2 pounds, and dogs ingesting these large amounts have developed kidney failure. Any dog that ingests large amounts of grapes or raisins at one time should be treated aggressively, so contact your veterinarian immediately if ingestion has occurred. Eating a few here and there has not been proven to be toxic.
Herbal Medications. While most plants used have beneficial properties, it is important to remember that the strength of the plant's active ingredients will vary with the variety of herb and the horticultural practices used to grow them. Herbs can be sprayed with pesticides, fungicides or fertilizers. They may have been fertilized with improperly prepared compost, which can harbor harmful bacteria. They may produce more than one active compound causing unwanted side effects, which may worsen some medical conditions. There are no standards for quality control in production and dosages. Onion, garlic, pennyroyal and ginseng are a few of the commonly used herbal preparations that can cause toxicities if used inappropriately. Many have vomiting and diarrhea as a side effect. Even if your pet is taking an herbal supplement without complication, make sure your veterinarian knows what you are giving. Some herbs interfere with other health concerns and other medications.
Ibuprofen. Ibuprofen is a popular and effective over-the-counter medication available to treat pain and inflammation in people. For dogs, ibuprofen can easily exceed toxic levels. The most common cause of ibuprofen toxicity is a well-meaning dog owner who tries to alleviate pain in his dog by administering a dose he thinks is adequate without knowing the toxic dose. The initial toxic effect is bleeding stomach ulcers. In addition to ulcers, increasing doses of ibuprofen eventually lead to kidney failure and, if left untreated, can be fatal. Symptoms include poor appetite, vomiting, black tarry stools, vomiting blood, abdominal pain, weakness and lethargy.
Inhaled Toxins can be toxic to dogs.
Carbon Monoxide Poisoning is typically associated with confinement in a running vehicle but can also occur in a home with improper ventilation and faulty furnaces. If you suspect that your pet has been exposed to carbon monoxide, remove him from the scene and place him in an area with fresh air. Contact your veterinarian or local emergency facility for further instructions.
Smoke inhalation is another common inhaled toxin.
Iron. Iron is a chemical element that is important to red blood cell production in the body. It is found in a variety of supplements and vitamins. Iron toxicity typically occurs after accidental ingestion of the supplements or from overdoses of supplements. Iron comes in a variety of forms and the forms that may result in toxicity are: ferrous fumarate, ferrous sulfate, ferric phosphate, and ferrous carbonate. Toxic levels of iron cause damage to the stomach and intestinal lining as well as cause severe liver damage and heart damage. The first signs generally occur within six hours of eating a toxic amount. Even without treatment, your dog may appear to have improved after the initial gastrointestinal upset. Unfortunately, spontaneous recovery has not really occurred and about 24 hours later, diarrhea returns along with liver failure, shock and possible coma. Bleeding disorders can also occur. See your veterinarian immediately if you suspect iron toxicity.
Ivermectin. Ivermectin is an anti-parasite drug that causes neurologic damage to the parasite, resulting in paralysis and death. Ivermectin has been used to prevent parasite infections, such as heartworms or ear mites. Causes of ivermectin toxicity in dogs include administration of excessive doses and breed sensitivity to lower doses (which occurs in some breeds such as the collie or Australian shepherd). Toxicity can result in any number or combination of clinical signs including dilated pupils, depression, drooling, vomiting, tremors, disorientation, weakness, recumbency (inability to rise), blindness, unresponsiveness, slow heart rate, slow respiratory rate, coma or death.
Lead. Lead toxicity refers to poisoning due to ingestion or inhalation of products containing the element lead. Dogs may be exposed to lead from several different sources. Lead toxicity can cause anemia (low red blood cell count), gastrointestinal symptoms (vomiting, diarrhea) and nervous system problems (seizures). Lead crosses the placenta from pregnant mother to babies and is also excreted in her milk. Thus, the developing fetus and nursing young can be affected. See your veterinarian if you suspect lead exposure.
Marijuana. The primary active ingredient in marijuana is tetrahydrocannabinol or THC. It takes about 1.5 grams of marijuana per pound of body weight to be fatal. Therefore, death from ingested marijuana is not common. However, dogs ingesting marijuana become incoordination and begin stumbling. Most become quite lethargic. Some may experience hallucinations. The danger with marijuana is that vomiting is common, and if the pet is profoundly lethargic and begins vomiting, aspiration of the vomitus into the lungs can lead to severe breathing problems and even death. Treatment of marijuana exposure usually involves the induction of vomiting to remove any residual THC and, depending on the severity of the signs, some pets require hospitalization with intravenous fluids. The vast majority of pets exposed to marijuana fully recover within 24 hours.
Medication. Never give any medication, prescription or over-the-counter, without approval from your veterinarian. There are several medications available for people that can help animals but you must be careful to give the correct medicine at the proper dose. Some common medications that can have serious effects on animals if not used correctly include: pseudoephedrine, aspirin, acetaminophen, ibuprofen, Imodium®, diphenhydramine and Claritan. If your pet has ingested an unprescribed medication, contact your veterinarian or local veterinary emergency facility. Give the name of the medication, how many and what dose your pet received, what time the ingestion could have occurred, as well as pet information such as breed, age and any health problems he/she may have. You may receive instructions for what to do at home or what to watch for. In some situations, emergency examination and treatment are crucial.
Metaldehyde. Metaldehyde poisoning results from the ingestion of products containing the active ingredient metaldehyde. This is a common ingredient used in molluscicides, which are products used to kill snails and slugs. Metaldehyde toxicity causes rapid onset of neurological symptoms that begin 1 to 4 hours after exposure. Repeated seizures can cause a very high body temperature, which can lead to complications that are fatal. Affected pets usually require hospitalization for 24 to 72 hours after metaldehyde ingestion.
Metronidazole. Metronidazole is a commonly used and very effective antibiotic. Unfortunately, as with all drugs, toxicity and adverse effects can occur. However, toxicity from metronidazole is uncommon and is generally associated with prolonged use (many weeks) or high doses of the drug. Animals with underlying liver disease are more prone to metronidazole toxicity. Toxic levels of metronidazole affect the brain and equilibrium. Symptoms include: not eating, vomiting, staggering or difficulty walking, involuntary and constant eye movements (nystagmus), lethargy, and seizures. There is no home care for metronidazole toxicity. If you suspect that metronidazole is responsible for illness in your pet, consult your veterinarian.
Mushrooms. Mushroom poisoning occurs as a result of ingesting toxic mushrooms. Not all mushrooms are poisonous, but each type of poisonous mushroom can cause different signs of illness. Poisonous mushrooms are classified into four main categories, based on the clinical signs they cause, or into seven categories, based on the toxins they contain. The onset of clinical signs may occur anywhere from minutes to hours following ingestion. Signs may include: vomiting, diarrhea, abdominal pain, lethargy, jaundice (yellow skin color), seizures, coma and/or excess salivation. There is no adequate home care for poisonous mushroom ingestion. If you suspect that your dog has eaten a dangerous mushroom, contact your veterinarian immediately.
Mycotoxins. Mycotoxins are toxic substances secreted by molds and are commonly ingested when dogs raid the trash. Ingestion of certain moldy foods can result in signs of illness, primary whole body tremors. If left untreated, the tremors worsen and can progress to seizures. The dog's body temperature increases and heat-related complications can occur. The most commonly implicated moldy foods are dairy products and pasta, but any mold may develop the specific toxins. Dogs that do not receive treatment may not survive.
Naproxen. Naproxen is a popular and effective over-the-counter medication available to treat pain and inflammation in people. For dogs, naproxen can easily exceed toxic levels. The most common cause of naproxen toxicity is a well-meaning owner who tries to alleviate pain in his dog by giving the medication without knowing the toxic dose. The initial toxic effect is bleeding stomach ulcers. In addition to ulcers, increasing doses of naproxen eventually leads to kidney failure and, if left untreated, can be fatal.
Nicotine. Nicotine is found in a variety of sources, primarily cigarettes, cigars, tobacco, nicotine gum and nicotine patches. The toxic level of nicotine in dogs is 5 milligrams of nicotine per pound of body weight. For example, one cigarette contains 15 to 25 milligrams of nicotine, and nicotine patches contain between 8 to 114 milligrams of nicotine. A 10-pound dog would only need to eat 2 to 4 cigarettes in order to show toxic signs. You should note that even after smoking, tobacco retains a significant amount of nicotine residue. Signs of nicotine toxicity generally develop soon after ingestion and include vomiting, drooling, excitement, tremors, low heart rate or seizures. When large amounts are consumed, the effects can be life-threatening, but even small amounts can induce symptoms. Without treatment, nicotine toxicity can cause paralysis of the breathing muscles and your dog may die from an inability to breathe, sometimes within a few hours. If your pet has ingested nicotine, call your veterinarian.
Onions. Onion toxicity can be caused from raw onions, cooked onions, onion powders or flavorings. Canines lack the enzyme necessary to digest onions properly and this could result in gas, diarrhea, or severe gastrointestinal distress. If large amounts of onion are ingested or onions are a daily part of your dog's diet, the red blood cells may become fragile and break apart. Severe anemias and even death can occur if the dog ingests lots of onions and receives no treatment.
Organophosphate Insecticides. An organophosphate is a type of insecticides used to treat insects on our crops and soils, prevent and treat flea infestations, and are used in ant and roach baits. The majority of toxicities related to this chemical are due to improper use of the chemical, especially when many different types of insecticides are used at the same time. The canine formula should never be used on cats. Overdosing has also resulted in toxicity. Organophosphates affect the nerve-muscle junctions. Without a normal nerve impulse through the muscle, the function of the muscle is impaired. Since muscle tissue is present in the intestinal tract as well as the heart and skeleton, various signs may be seen if a pet is exposed to toxic levels of this insecticide. Symptoms include: vomiting, diarrhea, drooling, difficulty breathing, muscles tremors, twitching, weakness and paralysis. Prompt veterinary care is required to survive a toxic exposure.
Potpourri. Curious dogs often find simmering potpourri pots irresistible. Not only are burns a potential problem but the potpourri is caustic. Ingesting or even licking the potpourri can result in chemical burns to the tongue, throat and esophagus. Severely burned pets may require hospitalization with feeding tubes until the wounds heal.
Pyrethrin and Permethrin Insecticides.The most common types of insecticide used to kill fleas are pyrethrins. Toxicity related to pyrethrins is usually associated with applying much more of the product than directed. Permethrin is a stronger synthetic insecticide that has a much greater potential for resulting in toxicity. Permethrin-based topical flea products are usually labeled “for use in dogs only.” Application of permethrin-based insecticide to a cat will usually result in toxic signs within 6 hours. Overdosing can cause toxic signs in both dogs and cats. Signs include drooling, lethargy, muscle tremors, vomiting and seizures. If you suspect your pet may have permethrin/pyrethrin toxicity, the most important part of home care is to bathe your pet in lukewarm water using mild dish soap. Do not use flea shampoo. Avoid hot water since that will dilate blood vessels in the skin and increase the absorption of the flea product. Once the pet is bathed, contact your veterinarian or local veterinary emergency facility immediately.
Toxicity of Common Plants in the House. Houseplants are popular additions to many rooms. Usually, plants and pets live together harmoniously, although some curious pets often venture to take a little taste. See the related article to find out about the 20 most popular houseplants and their levels of toxicity.
Plants - Fall and Winter. This link takes you to the common plants associated with the fall and winter holidays.
Plants - Spring and Summer. Springtime holidays are often associated with bulb plants and ingestion of the bulbs can cause the most severe illnesses. Summer holidays are associated with plants. This link takes you to the common plants associated with the spring and summer months.
Poison Ivy and Oak. The principal toxin in poison oak and poison ivy is urushiol, which is an oil resin found in the plant sap. Animals are quite resistant to the effects of urushiol but can transmit the toxin to a person. Dogs and cats typically come in contact with the poison ivy or poison oak plant in wooded areas. They may ingest some of the plant but, more likely, they will rub against it while walking. The sap from the plant can adhere to the hair coat. When you pet your dog or cat later, the sap can transfer from their fur to your skin. If you are susceptible to poison oak or poison ivy, skin irritation can occur. In animals, exposure to urushiol infrequently results in skin irritation.
Rat Poison. Rodenticide poisoning is the accidental ingestion of products used to kill rodents such as mice, rats and gophers. These products are common and accidental exposure is frequent. Poisoning is most commonly caused by ingestion of a product containing one of the following ingredients: bromethalin, cholecalciferol (Vitamin D3), strychnine, zinc phosphide and anticoagulants (such as warfarin, fumarin, chlorophacinone, diphacinone, pindone, bromadiolone, brodaficoum). The impact on the poisoned animal varies depending on the type of poison ingested. An animal may develop a bleeding disorder, neurological problems, gastrointestinal distress or kidney failure. In some cases, rodenticide poisoning is fatal. If you suspect that your pet has ingested rat poison, call your veterinarian immediately.
Rimadyl. Rimadyl toxicity describes the symptoms of poisoning associated with the administration of Rimadyl® (carprofen), a non-steroidal anti-inflammatory medication used for the treatment of arthritis. This drugs suppress inflammation and pain by inhibiting synthesis of the class of compounds called prostaglandins. Rimadyl® toxicity can cause damage to the gastrointestinal tract, liver and kidneys. If accidental ingestion has occurred, remove any remaining pills from the pet's environment. Take your pet to a veterinarian as soon as possible for treatment of an overdosage of Rimadyl®. If you have been administering Rimadyl® and you note vomiting, black tarry stools, pale or yellow gums or loss of appetite, stop administering Rimadyl® and take your pet to a veterinarian as soon as possible.
Smoke Inhalation. Smoke can create significant damage within the airways. Pets, as well as people, can quickly succumb to the effects of smoke inhalation. If your pet is exposed to smoke, remove him immediately from the area and provide him with access to fresh air. If oxygen is available, offer by face mask. Contact your veterinarian or local emergency facility immediately. Your pet will require additional medical treatment for a successful outcome.
Strychnine. Strychnine is a toxin derived from the seeds of Strychnos nux vomica and S. ignatii and is used to control rats, moles and other predators. However, when ingested by dogs, it is extremely toxic, and can cause death. Direct exposure to bait is the most common cause in dogs, although intentional poisonings are not uncommon. Toxicity can also occur from the ingestion of poisoned rodents and birds. The primary effect of the toxin is on the neurological system. The toxin interferes with inhibitory transmitters, which produce a state of muscle rigidity and stimulation. Death is often caused by the effect on muscles that stimulate breathing. If you witness your dog ingesting strychnine, contact your veterinarian at once. He or she may direct you to induce vomiting immediately, if it is within minutes of ingestion. Take all poison packages with you to your
