Hair loss on the back of a dog. The dog has sores on its back and hair falls out and severe itching: photo and treatment of diseases. Vitamins for dogs

Pomeranians and other northern dogs with thick undercoats are prone to developing a hair cycle disorder called Alopecia X. Hair loss can be caused by many different conditions. This condition can only be diagnosed after more common hormonal disorders have been ruled out.

Knowing breed-specific diseases helps veterinary dermatologists make a quick and efficient diagnosis.

This type of baldness is commonly referred to as " endocrine alopecia as it is common in some types of hormonal imbalances (particularly hypothyroidism).

If your dog is shedding hair and you notice dark patches appearing in that spot, you should be concerned about what caused it. It is important to find out if this is a sign of something serious and if it causes discomfort to your dog. Symptoms may be a sign of alopecia X.

The condition we call Alopecia X, however, is not related to the hormonal imbalance that usually causes endocrine alopecia. Its causes remain unknown until now, hence the name alopecia X. There are many treatments that work in some cases and not in others. And many of these treatments seem to be in complete opposition to each other. Perhaps alopecia X is not one disease, but several, but at the moment there are no known ways to distinguish between them.

What is alopecia X?

Alopecia X is also known by the names:

  • black skin disease
  • Growth hormone responsive alopecia
  • Castration alopecia
  • pseudo-cushing syndrome
  • biopsy sensitive alopecia
  • Follicular dysplasia
  • Adrenal sex hormone alopecia

The following are what are currently believed to be facts about this confusing state.

The good news is that alopecia X is only an external (cosmetic) condition. The dog does not show any flaws, except that it may look funny. For this reason, drug treatment is most often not recommended. Medicines can affect the whole body, but the disease itself does not. In addition, such treatment is fraught with consequences and can be expensive, depending on which therapy is chosen.

Photo manifestations of Alopecia X in dogs

There are no signs of systemic disease associated with alopecia X. If your dog does not eat or drink (or eats and drinks excessively), is depressed, misbehaves, or has elevated liver or kidney values, then it is important to look for another cause of hair loss. . Since these same symptoms can be recognized in a number of other diseases of the endocrine system, including Cushing's disease and hypothyroidism. It is best to have your complete blood and chemical analysis, including appropriate endocrine testing, to rule out these alternatives.

Treatment of alopecia X

Treatment for alopecia X is often trial and error because the underlying cause of this disorder is unknown. There are ways to help stimulate hair growth because it is an external (cosmetic) manifestation and the health of the affected dog is not impaired. The above treatment is also a perfectly reasonable option. However, there are several options for loving owners who want to eliminate these symptoms.

The first strategy is to focus solely on the hair follicle itself. Your veterinary dermatologist can correct mucosa, relieve blockage, and stimulate hair follicle growth while normalizing skin maturation with oral retinoid therapy (associated with vitamin A). This should be combined with a melatonin supplement to normalize the appearance of the skin at the same time. Alternatively, a topical glycol shampoo can also be used to help exfoliate the skin and stimulate hair growth.
