The dog's hair falls out - causes and signs of diseases

Caring for your pet starts with care. If the dog began to lose hair sharply, and the molting period is far away, you should pay attention to the state of his health. Hair loss is a symptom of several diseases, a signal of disorders in the body.

Why does a dog’s hair fall out?

Only a specialist can answer the question, but not without the help of the owner of his patient. The reasons why a dog’s hair climbs are conventionally divided into two categories: hormonal and non-hormonal. Hormonal diseases accompanied by loss of coat:

  • a lack or excess of estrogen leads to a gradual depletion of hairs, and then the dog’s hair falls out;
  • significant hair loss is observed in Cushing’s syndrome, when there is an excess of a certain hormone in the dog’s body, there is a sharp weight gain and constant thirst;
  • when the dog is actively gaining weight, the hairs on the body begin to break off and all this is accompanied by lethargy, there is a possibility of hypothyroidism;
  • there is a whole list of breeds that are characterized by a deficiency of growth hormone, it causes baldness in a young animal during puberty.

A dog can also lose its hairline for other reasons that have nothing to do with an excess or lack of hormones:

  • many breeds begin to lose hair too actively during molting;
  • stress or a strong shock quite noticeably affects the appearance of the dog, her hair falls out after moving or a visit to the veterinarian, many pets react to a change in food or shampoo;
  • bald patches in certain areas are sometimes a problem of a particular breed, for a dachshund a black acanthosis is considered a typical disease, a color mutational alopecia is often found in a Doberman;
  • allergic reactions are diagnosed in the vast majority of cases, in such a situation, hair loss is accompanied by scabies or dandruff;
  • for a young organism, parasites become the cause;
  • The dog’s hair falls out due to bacterial and viral infections.
  • black acanthosis

Dog is losing hair on its back

The back in the withers area is always more prone to baldness, since vaccinations and insect treatments fall on this part of the body. When the dog’s hair falls out strongly in these places, you need to examine the wound:

  1. The area of ​​the croup and sides of the back after baldness appears when affected by eczema. These are the so-called weeping wounds. If the combing of wool during molting was of poor quality, parasites appeared, or the animal did not accept new food and shampoo, such reactions are quite expected.

  3. An ear mite in the warm season is a likely source of the problem, because its appearance gradually depletes the hairline until hair loss.
  4. The dog has lichen, but the incubation period is long. Ringworm is not always accompanied by severe itching, therefore, it is not possible to recognize the problem in time.
  5. Lack of vitamins A, E leads to a deterioration in the condition of the skin and coat. The problem will manifest itself faster in a thin and vulnerable part of the body – on the pet’s ears.

Loss of hair on the tail of a dog

  1. The secretion of sebum is a source of nutrition for the coat, and when a dog’s hair falls out in places, this may be a signal of a failure in this very nutrition. If the gland secretes too much fat, it leads to baldness. Experts even gave the name to the problem “shabby tail”. Everything is solved by using salicylic acid and tar soap to remove excess fat and disinfect.

  3. Lice and fleas for a dog become a source of infection with helminths.

Loss of fur on dog’s belly

  1. Sometimes the dog’s hair climbs in shreds and this is normal for the molting period. When the undercoat is difficult to shed, skin diseases sometimes occur.
  2. When an animal literally gnaws its fur on its own, it is worth checking it for parasite infestation. Vlas-eaters feed on blood and the upper layer of the skin, gradually cutting off area by area. The dog will scratch his stomach when fleas appear, then lick the wound, and this process is endless until the appearance of open wounds.

  6. protrusion on the face

Dog losing hair on chest

In the chest area of ​​many breeds, the coat is dense and the hairs are long. During the molting period, the dog’s hair falls out in clumps if the undercoat goes badly. A similar picture is observed for the period of pregnancy. A bald chest is the result of a number of reasons:

  • hypothyroidism or a violation of the hormonal production of the thyroid gland will make itself felt by the gradual transition of bald patches from the chest to the sides and back of the pet, the dog becomes lethargic;

Dog has dandruff and hair loss

The hereditary condition of increased oiliness of the skin is the reason that the dog’s skin is flaky and hair falls out.

The dog itches a lot and the hair falls out

A tick that causes baldness and scabies can ruin the life of a dog of any breed, but it is more common in chapreys and bull terriers. Another reason why a dog itches and hair falls out is an infection with a scabies mite. If the bald spots are colored in a characteristic pink color and covered with a crust, the animal is infected with ringworm.

Dog hair loss after childbirth

It is believed that baldness after the appearance of offspring is quite a normal situation. Almost always, intervention from the owner is not required, the coat gradually grows back and the dog has enough quality food and vitamins as prescribed by the veterinarian. Even when the dog’s hair fell out and did not have time to grow back in a couple of months, there is no need to rush with the preparations. Some breeds lose their hair after they finish feeding their puppies.

The dog has hair loss and redness of the skin

Weeping wound with a red tint – typical of eczema. The source of the problem is parasites, allergies to food or care products, sometimes this is a consequence of poor-quality combing of the undercoat. The reason why a dog has a lot of hair from the genital area is hormonal abnormalities. Redness is often the result of constant scratching of the affected area or licking wounds.

Dog hair is falling, what should I do?

  3. Against the general background, it’s good to take care of the dog’s immunity, resort to the help of vitamins and preventive drugs. But everything is exclusively for its intended purpose and under supervision.
