Dog's coat is so greasy

My eight-year-old black labrador has developed a greasy and musty smelling coat. I have used our shampoos for greasy hair but soon after it's just as bad as before. Any suggestions?

Healthy black labradors should have a shiny silky coat. This is helped by regular brushing to remove dead hairs and sebum (produced by the sebaceous glands).

Shampooing is rarely needed, as a balance is achieved by production of the lustre-giving sebum and its removal by brushing and the dog's own grooming.
