Once you have restored your dog’s coat to health, it is important that you maintain that health with proper grooming habits. Brush your dog at least a few times a week, depending how heavily he sheds. Not only will regular brushing help to reduce shedding, but it will also help to distribute the natural oils produced in his skin that help to keep his coat healthy. Avoid over-bathing your dog because you could dry out his skin and coat, and don’t use any products that aren’t approved for dogs.
