to add to other groomers input...a dog with a double coat should be brushed properly( to the skin) and thoroughly at least once a week.Matts are painful to an animal and if they get wet and then dry they tighten up and this tends to pull the hair out by the root leaving raw spots under the matt and can also cause skin infection. Long haired double coated dogs should NOT be shaved with the exception of for health reasons such as dermatitis, tick issues, etc.On a double coated dog, if itt's well cared for the coat actually acts as a natural air conditioner or warmth insulator for the dog.
Don't use people shampoos on dogs either, the pH is wrong and tends to irritate/dry out skin .
