If you bathe your dog often, watch out for signs of painful earaches that can be problematic for canines. They can happen when too much water gets into the ears. Use cotton balls dabbed in baby oil while giving him a bath, and that should keep water from getting in, even if he splashes around.
Brush your dog's teeth every week. Use a child's toothbrush that is soft, some nylon pantyhose over your finger, or a gauze pad. Don't use regular toothpaste. Instead, try using a baking soda and water paste or toothpaste made for dogs. Clean their teeth one to two times a week.
