If you think your dog needs to lose a few pounds, slowly cut down its caloric intake. If you think your dog is not receiving enough vitamins and nutrients, consider adding a vitamin or mineral supplement to its diet. Consult your veterinarian. Contrary to popular belief, dogs do not need variety in their diet. Use the same type of food every day, and if you want to change the brand of dog food you are using, do so gradually.
Bad breath is a common problem with dogs.
It can be created from food, tartar deposits on teeth or from digestive problems. Feed your dog dry food and treats to help reduce plaque. Brush your dog's teeth once or twice a week with a toothbrush and dog toothpaste. You can also use a moistened gauze pad. Just like humans, it is unhealthy for a dog to be overweight.
