Why do pet dogs shed hair? These reasons are something dog owners should understand

First, seasonal shedding.

Most dogs shed and change their coat in spring and autumn, such as Shetland Sheepdogs, Chow Chows, Pekingese, and so on. In summer they need less fur, so when the weather turns warm they shed part of their old coat to regulate body temperature. As winter approaches, they shed the coarse hair and replace it with downy fur to get through the cold winter. These are all normal phenomena.

Second, if a dog suffers from diseases such as folliculitis or eczema, or is infested with dog lice and fleas, it can also cause heavy shedding.

Because of the itching, the dog scratches and pulls at its coat with its paws and teeth, tearing out large amounts of dog hair. You should find the cause and consult a relevant doctor or an experienced person to treat it accordingly.

Third, shedding caused by human factors.

Many families use adult bar soap, shampoo, or even detergent to bathe their dogs. This is because a dog's skin tends toward neutral, while adult cleaning products tend toward alkaline, which causes dry, itchy skin in dogs, giving mites, bacteria and fungi an opening to form skin diseases, ultimately leading to shedding. In addition, bathing too frequently greatly damages the protective substances normally secreted by a pet's skin. Therefore, you should use a special detergent for dogs, and bathing should not be too frequent.

Fourth, deficiency of vitamins and minerals in the body.

Sun exposure and natural environmental factors such as temperature also affect the growth of dog hair. If a puppy cannot get sunlight for a long time and is kept indoors all the time, it will also cause a slight shedding phenomenon all year round. There are also some breeds of dogs, such as the Dalmatian; although it is a short-haired breed, whenever you stroke it with your hand, even with slight pressure, your hand will be covered in dog hair, and this is unavoidable.
