Four Common Causes of Canine Hair Loss

---

     Your dog can begin to shed excessive hair for a number of reason. Some diseases that cause canine hair loss, or alopecia, can be very serious. A few of the most common causes include allergies, parasites, and various diseases. Let's take a look at some of these causes of canine hair loss.

Allergies

Allergies can cause your dog to lose some of his hair. There are various things that can cause an allergic reaction in your dog. He can be allergic to certain foods, metals, wool, plastic, or rubber. Chemicals in the carpet such as deodorizer and dye can also be irritants. Some dogs will suffer an allergic reaction from medications like antibiotics. You will have to eliminate the irritant or allergen so that your dog's hair will grow back.

Parasites

Parasites can also cause canine hair loss. Some dogs suffer a severe allergic reaction when they're bitten by a flea. In addition to losing their hair, these dogs also have redness, scales, and itching. If parasites are the cause of your dog losing hair, you will need to adopt a flea control method for the dog and environment. It may also be necessary for your dog to take antihistamines and steroids.

Cushing's Disease

Cushing's disease is one of the next most common causes. This disease can be caused by a tumor or prolonged use of steroids to treat another disorder. If it's caused by a tumor, treatment options may include surgical removal, radiation, or chemotherapy. If your dog is taking steroids to treat another condition, he should slowly be taken off of them.

Infections

Infections are one of the last common causes of canine hair loss. An infection from sarcoptic mange or ringworm is most likely. Both of these conditions can be treated by giving your dog a bath using a special shampoo. If your dog is infected with ringworm, you may also have the option of giving him an oral medication.
