Alopecia In Dogs

What is Alopecia In Dogs?

Have you ever seen a dog losing its hair completely? Or, is your pooch getting bald spots here and there? Do you know the reason behind baldness? This disorder in canines is termed “Canine Alopecia”.

It is common in dogs. It occurs as a result of genetics or underlying medical conditions such as hyper and hypothyroidism, Cushing’s disease, and Addison’s disease.

If your dog has poor blood circulation, hair growth will not be good. Also, dogs having a weak heart, chronic anemia, and low blood pressure will have dull skin and coats.

If it loses hair without itching, it is an autoimmune disorder called “Alopecia Areata.” In such cases, your canine will have a sudden loss of hair with circular bald patches.

And, you can see your pooch is losing its hair on the head, neck, and body.

Vets confirm this condition by microscopic examination of hairs or biopsy in a few cases. Your doggy’s hair will automatically regrow in a time span of 6 to 12 months but with a light color.

Sometimes, your dog may get itching and then lose its hair. It may be either due to infections from scabies and fleas or from mange, a skin disease.

Sprays, creams, and hydrocortisone shampoos may also be used to treat the itchy skin. They can also promote healing and you can apply the sprays directly onto the itchy area.

Scabs may occur because of allergies, parasitic infections, and fungal infections. Hypothyroidism and Cushing’s disease can also lead to this condition. This condition can be diagnosed through physical examination.

Vets prescribe fungal culture, bacterial culture, cytology, skin biopsy and other allergy tests.

  • Antibiotics (either topical or oral) to treat bacterial infections
  • Antifungal (either oral or topical) medications to treat ringworm and yeast infections.
  • Behavioral medications to avoid licking or chewing the affected area.

  • Your vet may also recommend an Elizabethan collar (e-collar or cone). This is to prevent the pet from licking the affected site until it healed.
  • Insulin therapy to cure hair loss associated with diabetes.
  • Medicated shampoos or dips to treat hair loss occurring due to mange. Melatonin may also be used to treat hair loss in dogs.

Contact allergies - Dogs will also get allergies just by walking through grass or from carpets or floors that are chemically treated.

Allergens: Pollens are the major allergens. Besides, perfumes and cigarette smoke may also add to the list of allergens. If your dog inhales any of these allergens, it will get allergies. Itchy skin will also lead to Excessive Scratching or chewing out the hair.

Parasites are the major cause of alopecia in dogs. The foremost among them is the external parasites such as mites, fleas, ticks, and lice. Your dog will also feel Excessive Scratching and itching, in addition to hair loss, due to these parasites.

Next to parasites, bacteria are one of the major factors causing alopecia. In fact, bacteria are the common cause for multifocal alopecia (i.e. hair loss in multiple areas of your dog’s body). Such kind of bacterial infections may also lead to crusting in skin, redness and hair loss in circular patterns.
