Small amounts of avocado may not cause any problems for your pooch, but if consumed in large amounts, the fruit can cause gastrointestinal problems and even pancreatitis. Besides the high fat content, avocados are dangerous because of persin, which while safe for humans, is considered a toxin for some animals, especially birds.
Used as a sweetener in baked goods, toothpaste, and even peanut butter, xylitol’s insulin-like effect on pets makes it one of the most common toxins, Hackett says. Some indications of xylitol consumption include tremors, a drop in blood sugar and becoming profoundly weak. “Most often this reaction occurs when a dog gets into a full box of cookies,” Hackett says. If this happens to your dog, take them to your vet who will probably stabilize the pet’s blood sugar using an intravenous sugar solution, Hackett says.
Onions and Garlic
While trace amounts of onion and garlic powder appear in dog food, whole onions and garlic can cause pets to become anemic. (Tylenol has the same effect on pets.) “Cats in particular do not process the sulfur containing compound found in onions and garlic well,” Hackett says. Symptoms might not develop for a few days, but weakness and inability to move could be indications of onion or garlic consumption. If you suspect your pet has consumed onions or garlic, take your pet to the vet.
