Asparagus can be eaten by dogs. The tender cooked stalk and tips, which are what we eat, are safe for dogs to eat. It’s important to remember that asparagus ferns are toxic to pets. They won’t kill your dog, but they may cause diarrhea and digestive problems. However, raw asparagus should not be given to your dog because it can cause choking. As a result, always feed grilled asparagus to your dog if you want him to eat it safely.
