Mites and parasites.

Other reasons your dog may lose hair are from mites and parasites. You’ll probably want to discuss these concerns with your vet, especially if hair loss is in tandem with other symptoms. If your dog is shedding fur excessively, it could mean they have mites. Mites can cause your dog to lose hair at an accelerated rate. If your dog is shedding more than usual, you should definitely bring them to the vet to confirm a case of mites.

Parasites cause infections in the skin. The most common infection is from ticks, flea allergy, and chiggers. If your pet has developed an inflammation due to an infection or tick/flea bite, they will create rashes that usually ossify over time. They also produce thickened skin which will cause your dog to lose fur. The thickened skin and irritated skin will make it very difficult for them to maintain proper hygiene, thus making them vulnerable to infections.

Fungal infections.

A third common cause of hair loss around the head is fungal infections. Fungal infections are commonly mistaken for skin irritation or allergies. It is important to note that all types of fungal infections will leave your dog with hair loss around the tail. You may see redness, itching, and scratching associated with the patches of irritated dogs skin, but they are hair follicles dying off.


Nutrient deficiency.

If a fungal or bacterial infection does not cause your dog’s hair loss, it could be caused by a nutrient deficiency. A deficiency of vitamin A, B, or E can result in a cat-like trait where your pet licks its paws, eats its fur, or even sharts itself. This is not a normal sign and indicates a serious deficiency. A deficiency of these nutrients results in lower production of sebum (the oil that coats our skin), lower levels of the chemicals (paracephenol A and phenyl oxalate) that help our skin stay healthy, and decreased photosynthesis of fatty acids. All of these changes in the thyroid gland hormones can affect hair growth. Your pet may begin to shed more than usual as it loses more of its body hair, and you may see a few gray strands in its coat.

Do dogs lose hair because of stress?

Animals with sensitive skin are susceptible to extreme stress or anxiety within their lives could cause hair loss. In some instances, hair loss is a physical sign of stress; however, other times dogs engage in compulsive brushing that causes hair loss in the areas they frequently lick.


Dull coat.

Other common symptoms include a dull coat. Hair becomes thinner over time and becomes weaker in strength. Some may even notice loose skin in some areas of the coat. Grey or white hairs in the undercoat or on limbs or other body parts are signs that the underlying coat has been damaged. The dog’s overall coat texture changes, and the animal exhibits other changes such as a dry or rough coat, frequent ear cleaning, and general thinning and dulling of the coat.




Because of the constant stresses your dog goes through from life, he’s more susceptible to losing hair at the base of his tail. If your dog starts to lose hair at the base of his tail, take him to the vet. The vet can do tests to determine what is going on and may even recommend that your dog be treated with hormone treatment to restore his natural testosterone levels to normal, which will boost his immune system, prevent stress, and encourage proper hair growth.
