Total Health for your pet
Below is a list of some foods and medications that are toxic to your pet. If you are unsure, contact us immediately.
Chocolate, Coffee, Caffeine
These products all contain substances called methylxanthines, which are found in cacao seeds, the fruit of the plant used to make coffee and in the nuts of an extract used in some sodas. When ingested by pets, methylxanthines can cause vomiting and diarrhea, panting, excessive thirst and urination, hyperactivity, abnormal heart rhythm, tremors, seizures, and even death. Note that darker chocolate is more dangerous than milk chocolate. White chocolate has the lowest level of methylxanthines, while baking chocolate contains the highest.
Alcoholic beverages and food products containing alcohol can cause vomiting, diarrhea, decreased coordination, central nervous system depression, difficulty breathing, tremors, abnormal blood acidity, coma and even death.
The leaves, fruit, seeds and bark of avocados contain Persin, which can cause vomiting and diarrhea in dogs. Birds and rodents are especially sensitive to avocado poisoning, and can develop congestion, difficulty breathing and fluid accumulation around the heart. Some ingestions may even be fatal.
Macadamia nuts are commonly used in many cookies and candies. However, they can cause problems for your canine companion. These nuts have caused weakness, depression, vomiting, tremors, and hyperthermia in dogs. Signs usually appear within 12 hours of ingestion and last approximately 12 to 48 hours.
Grapes and Raisins
Although the toxic substance in grapes and raisins is unknown, these fruits can cause kidney failure. In pets who already have certain health problems, signs may be more dramatic.
Xylitol is used as a sweetener in many products, including gum, candy, baked goods, and toothpaste. In can cause insulin release in most species, which can lead to liver failure. The increase in insulin leads to hypoglycemia (lowered sugar levels). Initial signs of toxicosis include vomiting, lethargy, and loss of coordination. Signs can progress to recumbancy and seizures. Elevated liver enzymes and liver failure can be seen within a few days.
Onions, Garlic, Chives
These vegetables and herbs can cause gastrointestinal irritation and could lead to red blood cell damage. Although cats are more susceptible, dogs are also at risk if a large enough amount is consumed. Toxicity is normal diagnosed through history, clinical signs and microscopic confirmation of Heinz bodies. An occasional low dose, such as what might be found in pet foods or treats, likely will not cause a problem, but we recommend that you do NOT give your pets large quantities of these foods.
Below is a list of the top 10 human medications most frequently ingested by pets.
NSAIDs (e.g. Advil, Aleve and Motrin)
Topping our Top 10 list are common household medications called non-steroidal anti-inflammatories (NSAIDs), which include common names such as ibuprofen (e.g., Advil and some types of Motrin) and naproxen (Aleve). While these medications are safe for people, even one or two pills can cause serious harm to a pet. Dogs, cats, birds and other small mammals (ferrets, gerbils and hamsters) may develop serious stomach and intestinal ulcers as well as kidney failure.
Acetaminophen (e.g. Tylenol)
When it comes to pain medications, acetaminophen (e.g. Tylenol) is certainly popular. Even though this drug is very safe, even for children, this is not true for pets—especially cats. One regular strength tablet of acetaminophen may cause damage to a cat’s red blood cells, limiting their ability to carry oxygen. In dogs, acetaminophen leads to liver failure and, in large doses, red blood cell damage.
Antidepressants (e.g. Effexor, Cymbalta, Prozac, Lexapro)
While these antidepressant drugs are occasionally used in pets, overdoses can lead to serious neurological problems such as sedation, incoordination, tremors and seizures. Some antidepressants also have a stimulant effect leading to a dangerously elevated heart rate, blood pressure and body temperature. Pets, especially cats, seem to enjoy the taste of Effexor and often eat the entire pill. Unfortunately, just one pill can cause serious poisoning.
ADD/ADHD medications (e.g. Concerta, Adderall, Ritalin)
Medications used to treat Attention Deficit Disorder/Attention Deficit Hyperactivity Disorder contain potent stimulants such as amphetamines and methylphenidate. Even minimal ingestions of these medications by pets can cause life-threatening tremors, seizures, elevated body temperatures and heart problems.
Benzodiazepines and sleep aids (e.g. Xanax, Klonopin, Ambien, Lunesta)
These medications are designed to reduce anxiety and help people sleep better. However, in pets, they may have the opposite effect. About half of the dogs who ingest sleep aids become agitated instead of sedate. In addition, these drugs may cause severe lethargy, incoordination (including walking “drunk”), and slowed breathing in pets. In cats, some forms of benzodiazepines can cause liver failure when ingested.
Birth control (e.g. estrogen, estradiol, progesterone)
Birth control pills often come in packages that dogs find irresistible. Thankfully, small ingestions of these medications typically do not cause trouble. However, large ingestions of estrogen and estradiol can cause bone marrow suppression, particularly in birds. Additionally, female pets that are intact (not spayed), are at an increased risk of side effects from estrogen poisoning.
ACE Inhibitors (e.g. Zestril, Altace)
Angiotensin-converting enzyme (or “ACE”) inhibitors are commonly used to treat high blood pressure in people and, occasionally, pets. Though overdoses can cause low blood pressure, dizziness and weakness, this category of medication is typically quite safe. Pets ingesting small amounts of this medication can potentially be monitored at home, unless they have kidney failure or heart disease. All heart medications should be kept out of reach of pets.
Beta-blockers (e.g. Tenormin, Toprol, Coreg)
Beta-blockers are also used to treat high blood pressure but, unlike the ACE inhibitor, small ingestions of these drugs may cause serious poisoning in pets. Overdoses can cause life-threatening decreases in blood pressure and a very slow heart rate.
Thyroid hormones (e.g. Armour desiccated thyroid, Synthroid)
Pets — especially dogs — get underactive thyroids too. Interestingly, the dose of thyroid hormone needed to treat dogs is much higher than a person’s dose. Therefore, if dogs accidentally get into thyroid hormones at home, it rarely results in problems. However, large acute overdoses in cats and dogs can cause muscle tremors, nervousness, panting, a rapid heart rate and aggression.
Cholesterol lowering agents (e.g. Lipitor, Zocor, Crestor)
These popular medications, often called “statins,” are commonly used in the United States. While pets do not typically get high cholesterol, they may still get into the pill bottle. Thankfully, most “statin” ingestions only cause mild vomiting or diarrhea. Serious side effects from these drugs come with long-term use, not one-time ingestions.
