A double-coated dog can still regulate its temperature with two layers of coat. The undercoat provides warmth in the winter and cools them in the summer. It does not make dogs shed less. Clipping the coat can seem like a good idea to reduce shedding, but sadly it is a fallacy. Clipping *may* permanently damage the topcoat and the natural cycle of hair growth, making the frequency and amount of shedding unpredictable, and in some cases, a constant feature. It is true that the risks are more pronounced in 'Spitz-type' dogs, including Huskies, Pomeranians, and, obviously, Spitzes, so owners of these dogs need to be more cautious about having their dogs clipped, and avoid it if possible. The Artful Dog Grooming Parlour advises against clipping any breeds that have a double coat and will only undertake to do so if it is in the welfare interests of the dog.
Using scissors to cut short the fur of a double-coated dog is equally as risky as using clippers to shave them, so it's not an advisable alternative. It is ok to lightly scissor a double-coated dog's fur, in what is called a 'silhouette trim' as long as it is only the topcoat and does not go too short.
Examples of Double-Coated Breeds include Border Collies, Cavalier King Charles, Corgis, Chows, Golden and Labrador Retrievers, German Shepherds, Great Pyrenees, Newfoundlands, Pomeranians, Siberian Huskies.
