Nuts and seeds for dogs are a great source of phytonutrients, omega-3 fatty acids, as well as essential vitamins and minerals. These nutrients boost the immune system, lower cholesterol levels, and prevent inflammation. Nuts and seeds are great additions to the canine diet, but not all of them are safe for dogs. Some of them are high in carbohydrates and fat, which are contributors to obesity and other health issues. Others are downright dangerous because of the natural toxins they produce. Always check whether the nuts or seeds you are about to add to your dog’s diet are safe to eat.
