Chocolate, Macadamia nuts, grapes…these foods may sound delicious to you, but they’re quite dangerous for our animal companions. We have put together a handy list of the top toxic people foods to avoid feeding your pet. As always, if you suspect your pet has eaten any of the following foods, please note the amount ingested and contact us or the ASPCA Animal Poison Control Center at (888) 426-4435.

Chocolate, Coffee and Caffeine

These products all contain substances called methylxanthines. 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.

Grapes and Raisins

Although the toxic substance within grapes and raisins is unknown, these fruits can cause kidney failure.

Macadamia Nuts

Macadamia nuts can cause weakness, depression, vomiting, tremors and hyperthermia in dogs. Signs usually appear within 12 hours of ingestion and can last approximately 12 to 48 hours.

Milk and Dairy

Because pets do not possess significant amounts of lactase (the enzyme that breaks down lactose in milk), milk and other dairy-based products cause them diarrhea or other digestive upset.

Nuts

Nuts, including almonds, pecans, and walnuts, contain high amounts of oils and fats. The fats can cause vomiting and diarrhea, and potentially pancreatitis in pets.

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.

Raw/Undercooked Meat, Eggs and Bones

Raw meat and raw eggs can contain bacteria such as Salmonella and E. coli that can be harmful to pets and humans. Raw eggs contain an enzyme called avidin that decreases the absorption of biotin (a B vitamin), which can lead to skin and coat problems. Feeding your pet raw bones may seem like a natural and healthy option that might occur if your pet lived in the wild. However, this can be very dangerous for a domestic pet, who might choke on bones, break a tooth, or sustain a grave injury should the bone splinter and become lodged in or puncture your pet’s digestive tract.

Xylitol

Xylitol is used as a sweetener in many products, including gum, some peanut butters, candy, baked goods and toothpaste. It 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 seizures. Elevated liver enzymes and liver failure can be seen within a few days.

Yeast Dough

Yeast dough can rise and cause gas to accumulate in your pet’s digestive system. This can be painful and can cause the stomach to bloat, and potentially twist, becoming a life-threatening emergency.

Corn Cobs/Pits

Fruits that contain pits like avocados, cherries, plums, peaches and nectarines can be harmful to your pet. Corn cobs are also not digestable in pets. If ingested, cobs and pits can cause intestinal blockages.
