Avocado is full of good-for-you fats that are great for humans, but can cause stomach upset in pets due to a compound called persin.
The actual cherry is safe for dogs, but all other parts of the plant, including the pit in the middle, are toxic because of the cyanide compound they contain. Be especially carefully of wild-growing cherry trees and shrubs that can drop fruit in your yard.
There's nothing wrong with sharing a few delicious kernels of fresh corn (or popcorn) with your pet. It's actually the cob that can cause problems because it can't be ingested and get lodged in the intestines causing an obstruction. So don't allow your dog to chew on corn cob
Fruits like peaches and plums make a healthy, sweet snack for humans, but contain pits that can lodge in a dog's intestines if ingested. (The seeds also contain cyanide.)
While this member of the allium family can help reduce cholesterol in humans, it causes damage to red blood cells in dogs. Garlic powder can be even more dangerous than fresh because it's so concentrated
Grapes are full of antioxidants that are thought to be helpful to human health. It's not known what compound is toxic to animals but these and currants can cause kidney failure in dogs.
These nuts provide healthy fats and protein to humans, but they are poisonous to dogs. While symptoms are typically mild, they can still be uncomfortable for your pet and include tremors and fever.
Milk packs a great calcium punch for people. But while dairy foods probably won't lead to a vet visit, they can upset your dog's stomach because canines are lactose intolerant.
Eggs are a great protein choice for people, but when raw they can be contaminated with E. coli or Salmonella. Even if they aren't, they contain an enzyme that can block B vitamin absorption in dogs.
Sushi is a delicious, healthy choice for humans (except pregnant women), but some raw fish can be infected with a bacteria that is dangerous for dogs. Cooking the salmon (and removing any fine bones) will make it safe.
This tart, tasty fruit is gorgeous in salads but poisonous to pets because it contains soluble oxalate, which can cause vomiting, diarrhea lethargy and more.
While chewing a piece of gum can help keep your sweet tooth in check, the Xylitol in some gums can cause low blood sugar and liver damage in dogs.
If you know or suspect your pet has ingested any of these foods, you should call your vet or the 24/7 Pet Poison Helpline (800-213-6680) for advice.
