3. Avocados

Everyone knows that avocados are extremely healthy and good for you, because of their high vitamin and Omega fatty acid content. However, what’s good for you is not necessarily good for your dog, and this is particularly the case when it comes to avocados.

Avocados contain Persin, a substance that is also found in the leaves and the bark of the avocado tree. Persin is harmful for dogs, however in a different degree depending on the size of the dog and some other factors.

Some dogs are not even affected by Persin, some get mildly nauseous, some vomit and some have more serious problems. It’s hard to tell what kind of reaction your dog will have to avocados so it’s best to avoid them altogether. The pit of the avocado is also dangerous if swallowed, so make sure to keep your avocados somewhere where your dog can find them.
