What Is the Function of an Undercoat in Dogs?

Does your dog have an undercoat? You can find out by taking a close look at the coat. If your dog has an undercoat, you can clearly distinguish two different types of hair. The topcoat hairs are somewhat longer and coarser, while the undercoat hairs are softer and shorter. The undercoat is dense and thick and is more visible in winter. In some dogs, the undercoat is easier to see in certain areas of the body, for example around the neck.

Why an Undercoat?

The undercoat helps your dog regulate its body temperature. It acts as a layer of insulation. This insulation protects not only against cold, but also against heat. The undercoat is also water-repellent. In addition, it protects your dog’s skin from sunburn, scratches, and insects.

A Built-in Dog Blanket

Many dog breeds have an undercoat. Well-known examples include breeds from colder regions such as huskies and malamutes. Popular golden retrievers and German shepherds also have an undercoat. For sled dogs, having an undercoat is not only pleasantly warm, it also allows them to lie down and sleep in the snow. These dogs always carry their own cushioning, soft, and insulating dog blanket with them!

Grooming

How exactly you should care for your dog’s coat depends on the specific coat type. Dogs with an undercoat often shed more heavily in spring and autumn. Because an undercoat consists of fine and fluffy hair, it can easily become tangled and matted. It can also retain moisture and dirt, which may cause skin problems. It is therefore important to brush dogs with an undercoat regularly. This keeps the coat clean and airy and the underlying skin healthy.
