Dogs cannot eat avocados. Avocados are high in fat, which may cause pancreatitis. Moreover, the toxic substance persin in avocado may cause diarrhea and vomiting in dogs.

Although some dog foods say that they contain avocados, they are actually extracted fruit oils, so they can be eaten with confidence. Avocado oil contains unsaturated fatty acids, which can add nutrients to the dog's hair and maintain the health of the dog's liver.
