Sardines are excellent for dogs

Sardines are a nutritional powerhouse for dogs. Because they're small and low on the food chain, they accumulate very little mercury compared to larger fish like tuna. They're rich in omega-3 fatty acids (great for skin, coat, and joints), protein, calcium, and vitamin D. Choose sardines packed in water with no added salt.
