There is nothing sadder for a dog owner than to see how his little friend’s hair falls out. The most important thing when it comes to alopecia, as it is medically known, is to identify the cause of hair loss to design the appropriate treatment plan.

Below you will find a list of the most common causes of this condition:

Allergies

It’s the most common cause and is one of the main signs. Allergies can be caused by the environment (pollen, mold, mites), Food allergies are another possible cause of hair loss. Typical symptoms are bites, scratches and hair loss.

Common Causes of Hair Loss in Dogs

Parasite infestation

If you don’t have good hygiene and good parasitic prevention, fleas, ticks and lice can cause havoc. There are other problems such as scabies that cause hair loss around the ears, eyes, abdomen and torso, along with other problems such as swelling of the area, itching and redness. The symptoms of ringworm are characterized by circular or irregular alopecia, inflammation and infected crusts.

Genetics

Genetics is another of the most common causes of hair loss. There are several breeds of dogs that are genetically more prone to alopecia than others. For example, the Chinese Crested or the Xolo of Mexico. It is also the case in other well-known breeds, such as the Doberman Pinscher, the Teckel, the Chihuahua, or the Whippet that sometimes suffer from uneven alopecia in the body following a curious pattern: the lack of hair is in the ears, the torso, the loin, the thigh or the lower part of the neck.

Decubital Ulcers

Calluses are correctly known as decubitus ulcers. These are lesions that are located in the elbows of dogs and other points of bone pressure (in hips) and hair that always abounded in these areas ends up disappearing with contact with hard surfaces regularly. This constant pressure and friction causes hair to fall, the skin hardens forming that “callus” and even cracks and bleeds. Pressure ulcers are very common in older dogs, especially large or giant breeds that have greater weight.

Cushing’s Disease

Hyperadrenocorticism, also known as Cushing’s disease, is a condition caused by the prolonged exposure of the body’s tissue to excessive levels of the hormone cortisol. Symptoms of Cushing’s disease include hair loss, darkening of the skin, and the development of a pot-bellied abdomen. Cushing’s disease commonly occurs in middle-aged to senior dogs.
