Toxic and Dangerous Foods for Pets

By Elizabeth Mason Woods for WebVet

Pets and poison is a growing concern among pet owners.  Household poisons are not the only thing that can harm your pets.  Many common household foods and drugs can also be toxic to your pets.  The following are foods that can be toxic or poisonous to your pets.

Avocados
Avocados contain a toxin known as persin.  Persin is found in various parts of the avocado and avocado trees (eg, leaves, rind, etc).  This toxin is known mostly to cause vomiting and diarrhea.  Birds and small pets seem most affected by the negative side effects of consuming avocado.

Beer
Not just beer…all alcohol.  Depending on how much alcohol your animal ingests, it can lead to vomiting, diarrhea, depression, difficulty breathing, coma, and possible death.

Chocolate
Chocolate contains a compound called theobromine that is toxic to pets.  If enough is ingested, your animal can suffer from vomiting, diarrhea, abnormal heart rhythms, tremors, seizures, and possible death. Cocoa mulch contains theobromine; the ASPCA advises dog owners to avoid using this fertilizer around unsupervised dogs, and dogs with indiscriminate eating habits since it can be toxic if ingested.

Candy
Chocolate is the most common candy that is toxic to pets, especially to dogs, cats and ferrets.  Any candy containing the sweetener xylitol can also be toxic to pets.

Caffeine
Caffeine is generally highly toxic to pets, having negative effects on both the cardiac and nervous systems.  Side effects can include vomiting, diarrhea, abnormal heart rhythms, tremors, seizures, and possible death.

Grapes and raisins
An unknown toxin in grapes and raisins can cause kidney failure and ultimately lead to death.  Symptoms of this poisoning can include hyperactivity, vomiting, diarrhea, and irregular heartbeat.

Nuts
An unknown toxin in nuts can have negative effects on the nervous, digestive, and muscular systems of your pet.  Symptoms can include muscle tremors, weakness, an upset stomach, vomiting, depression, inactivity, and stiffness.   Particularly avoid Macadamia nuts.

Onions
Onions, along with garlic and chives, are all part of the same species of plant—the Allium species.  Allium species plants contain sulfur compounds that can cause stomach irritation and possibly result in damage to red blood cells causing anemia. This is referred to as Allium poisoning.

Some human medicines
While some human medications are prescribed for pets by veterinarians, others can be highly toxic and fatal.  Acetaminophen, which is contained in Tylenol and other similar products, for example, can be fatal to cats.  Always consult with your veterinarian before giving human medication to a pet.

Xylitol (artificial sugar)
Xylitol is a sweetener used in many products including mouthwash, chewing gum, toothpaste, and various foods.  Because it is toxic to pets, products containing xylitol should not be given to your dog or cat.
