Foods to Avoid Feeding Your Dog

Avocados

Avocados make their own fungicide, called persin. Pretty cool, huh? But dogs are allergic to it (and some humans, too), so don't let your dog near that guacamole. Persin is found in the seeds, leaves, and bark of avocado trees, too, so if you have an avocado tree in your yard, keep your dog away.
