Many owners worry about the summer heat and choose to shave their dogs, but this is not the right approach. Dogs do not need haircuts, and they won't suffer from heatstroke simply because they have a lot of fur. For dogs with very thick coats, a simple trim is all that's needed; it's best not to shave them completely, as this can lead to other problems.
Most pet dogs have relatively thick fur, so some owners worry that the summer heat will cause their dogs to suffer from heatstroke or rashes. Therefore, they consider giving their dogs a full shave. However, this is unnecessary. A dog's coat provides effective protection. Even if it's hot in the summer, most dog breeds have good skin heat dissipation, so it won't affect their health. For thick-coated breeds like sled dogs with poor heat dissipation, some trimming may be necessary, but a full shave is still not recommended.
Why Dogs Don't Need Haircuts
1. A Dog's Fur Provides Protection. Scientific research has found that a dog's coat consists of three types of hair: guard hairs, undercoat, and decorative hairs. Each layer has its specific purpose. Guard hairs, which are coarse and long, cover the dog's entire skin and are the main layer. The undercoat is the fine fur that lies close to the dog's skin, filling the gaps between the guard hairs. Decorative hairs are found on the cheeks, ears, abdomen, and hind legs, serving a primarily aesthetic purpose. These three layers overlap, forming a protective ring around the dog's body for self-thermoregulation.
2. Maintaining Energy Balance. Under normal conditions, a dog's organs need to maintain an energy balance. If a dog is completely shaved, it will definitely disrupt the dog's ability to regulate its own body temperature, causing the coat's insulation and warming effects to become ineffective, and may even lead to disorders in some physiological functions. If a dog exhibits sensitivity to cold or heat, it is likely due to the disruption of its body's self-insulating functions after being shaved.
3. Protection from Insects. A dog’s fur is important for preventing mosquito bites. Because the coat is thick, mosquitoes generally cannot reach the dog’s skin. If the fur is shaved off, the dog will suffer more, especially from summer mosquitoes.
4. Cushioning from Bumps and Scrapes. A dense coat acts as a cushion for minor bumps and scrapes, protecting dogs from injuries during their activities. Removing a dog's fur is like taking away its natural armor. If the dog falls or bumps into something, it will be more prone to injury.
