Seafood can be a part of a healthy diet for dogs. They are packed with high-quality protein and loaded with omega 3-fatty acids. They also contain vitamins and minerals that boost the immune system. But not all seafood is suitable for dogs. Some fish and shellfish contain high levels of mercury and heavy metals, which can cause poisoning. Another thing to consider is your dog’s sensitivity to seafood. Some dogs have seafood allergies, and eating seafood can trigger allergic reactions. To prevent allergies, mercury poisoning, and other health issues, make sure to feed the types of seafood that are safe for dogs to eat and prepare them properly to get the maximum health benefits.
