Though this delectable fruit is much loved by humans, too much of a good thing is bad for your pet. Avocados have something called persin. It’s fine for people who aren’t allergic to it. Avocados are poisonous to birds, rabbits, donkeys, horses, sheep and goats. Are you willing to chance the health of your dog?
Persin is in the leaves, seed, and bark, as well as the fruit. So if you grow avocados at home, securely fence off avocado trees and cut limbs as high as your dog can jump.
