Green peas come in many forms, sugar snap peas, English peas and snow peas. They are all acceptable to give your dog as a treat. If a human can eat the shell of the peas, so can a dog. That being said, never give your dog garden or English pea shells. These shells can cause choking or internal blockages. 

Canned peas should never be given to a dog. The liquid to keep the peas fresh is high in sodium which is harmful to your dog. 

Dogs can eat fresh or frozen peas. 

Dogs’ diets should be primarily meat, anything else should be given sparingly.
