There are many reasons that dogs (and humans) lose their hair and it is commonly referred to as alopecia.

It is possible for dogs to develop alopecia without itching for the following reasons:


Inflammation and shrinkage of the thyroid gland are symptoms of hypothyroidism.

There is no itching or inflammation of the skin associated with this disease and it often results in dogs losing their hair.

Hereditary hair loss

The majority of dog hair loss is accompanied by itching but alopecia without itching is often hereditary. Alopecia color dilution (CDA) is a genetic condition that causes hair thinning and patchy hair loss in dogs.

In most cases hair loss does not itch but secondary skin infections may cause itching. A dull coat graying hair and melanoma are also symptoms of hereditary hair loss.

Pressure sores

Hair loss may occur when your dog keeps pressing or weighing on the same spot.

Hair loss can also be caused by constant pressure from a collar.

If your dogs collar area has thinning hair take it off every so often and do not reattach it.

Skin cancer

In dogs with skin cancer hair is often lost in the area of the tumor lump and this hair loss does not itch. Symptoms such as lumps that might be ulcerated should also be noted.

Post-clipping alopecia

How are these causes diagnosed?

When you bring your dog to the vet for hair loss the vet will take a few steps to diagnose it.

1. Examine the pattern of hair loss

Veterinary professionals can get a good idea of whats causing the problem by looking at the pattern. The loss of hair in patches is most often caused by ringworm or bacterial infection while the loss of hair in symmetrical patterns may be the result of thyroid or adrenal gland disorder.

Diet plays a huge role in everything as you probably already know. Humans and dogs alike will suffer from physical and mental problems as a result of what they eat.

  • Vitamin A. It supports the growth of hair cells and promotes sebum production.
  • Biotin. Fatty acids are also produced for the strengthening of hair.

A lack of these vitamins might contribute to your dogs hair loss. It does not mean you should give your dog three servings of these vitamins at once. Its important to keep in mind that too much of them can also be problematic.

Analyze the nutrients in your dogs usual meal to determine what they are lacking. Supplements or foods can be used to replenish the vitamins you are lacking. There are also some vitamins that can be applied topically such as vitamin E.
