Poison is a growing concern among pet owners. Household poisons are not the only thing that can harm your pets. The following are foods that can be toxic or poisonous to your pets.

Chocolate
Chocolate contains a compound called theobromine that is toxic to pets. If enough is ingested, your animal can suffer from vomiting, diarrhea, abnormal heart rhythms, tremors, seizures, and possible death. Cocoa mulch contains theobromine; the ASPCA advises dog owners avoid using this fertilizer around unsupervised dogs.

Avocados
Avocados contain a toxin known as persin. This toxin causes vomiting and diarrhea. Birds and small pets seem most affected.

Candy
Chocolate is the most toxic to pets but Any candy containing the sweetener xylitol can also be toxic for hem.
