Yes, dogs can eat clams in small amounts as a treat. Clams are a good source of protein, vitamin B12, and iron, and can be cooked or canned. However, it is important to make sure the clams are cooked thoroughly to avoid the risk of food poisoning. Raw clams can contain harmful bacteria, parasites, or viruses that can be dangerous to dogs. Additionally, some dogs may be allergic to shellfish, so it is best to introduce clams slowly and monitor your dog's reaction. It is also important to remove any shells from the clams, as they can pose a choking hazard or cause digestive problems.
