Double coats, also known as down hairs, ground hairs, or undercoat, are very fine, fluffy hairs closest to the skin on some mammals. Common dog breads that have undercoats include the German Shepherd, Pomeranian, Chow, Husky, Malamute and Samoyed. The hairs are short and crimped, which makes them highly efficient at trapping air and insulating the animal. This keeps them warm in the winter and cool in the summer. This brings us to the first myth:
Myth #1: Long-haired, double-coated dogs need to be shaved in order to be cooler during the summer.
Unless the dog has passed the point of no return in the matting department, the best type of grooming for these dogs is a vigorous undercoat raking with a special tool that helps remove the undercoat. This raking, followed by a bath, and a blow dry, will help separate the hair so the groomer can get to the rest of the undercoat.
Once the undercoat has been thinned out, the dog does feel cooler. The guard hairs on the top, which do not shed out, provide protection against the sun’s rays and actually insulate the dog from the heat. However, one might consider shaving a strip on their belly, so that they can lay on cool surfaces, and get maximum coolness. If mats are your main concern, then it’s best to simply keep up with them so they don’t get bad to the point of having to shave your dog.

Myth #2: Cutting a dogs hair off will cause the dog not to shed.
This is not necessarily true. Dogs with undercoats shed. After a cut, it may shed shorter hair, but it will still shed.
Myth #3: Don’t worry; it’ll grow back.
The most harmful myth, as far as the dog is concerned is ”Don’t worry, it’ll grow back.” Well, sometimes it will. However, the older the dog is, the less likely the guard hairs will re-grow. While the undercoat will re-grow, the upper hairs sometimes do not. This gives the dog a patchy, scruffy, frizzy appearance.
Also, a shaved dog is more susceptible to sunburn – skin damaged by UV rays. These are rays that the dog would not otherwise be exposed to. This, unfortunately, can be painful and take a long time to heal. The dog may have scaling and dandruff for quite some time, even after the hair has re-grown.
Dogs like poodles, Maltese, Shih Tzu’s, and other dogs, which do not have undercoat, require regular grooming and haircuts. But dogs with undercoats rarely need shaving. So shaving your long-haired, double-coated dog in the summer is not really necessary, according to some veterinarians. But there may be just as many veterinarians and groomers who hold the opposite opinion and this needs serious consideration, too. To shave or not to shave? This controversy is sure to continue.
