Seborrhea is another word for scaling or flaking skin. It can be caused by a variety of underlying problems – from mineral deficiencies and inherited skin problems to low humidity in the winter (causing dry skin). It is often more prominent in dogs that are obese as they can’t groom as well as some other breeds.
Some dogs respond to a great quality diet, good grooming and supplements with essential fatty acids (Omega-3 and Omeg-6 such as Salmon Oil). Salmon oil can really help give dogs a shiny coat.
If your dog has seborrhea, discuss his condition with your veterinarian. Some dogs with underlying skin infections may require antibiotics.
