Safe — plain, frozen-then-thawed or cooked peas make a good low-calorie treat.
Short answer
Yes, plain peas are a perfectly safe and nutritious snack for dogs. Cooked or thawed frozen peas make an excellent low-calorie treat that many dogs enjoy. Just be sure they are plain, with no added salt, butter, or seasonings. You can offer a few as part of their regular diet, but as with any new food, start with a small amount to make sure it agrees with your dog's stomach.
