There are some dogs that are naturally hairless.
But for most breeds, going bare or bald signals a larger problem at work. When dogs experience hair loss, known as alopecia, it could be a symptom of a medical condition or it could be hereditary. As a pet parent, brush up on the basics of hair loss in dogs, including the different types, causes and treatment options.
Types of Dog Hair Loss
Hair loss can often be diagnosed according to different patterns. Most causes come with their own pattern, making it easier to determine the best form of treatment. A common example would be flea infestation in a particular area that’s easy for a dog to chew at, such as the base of the tail or along the inside of the legs. The most common patterns of hair loss in dogs include:
All-over thinning of hair
Thinning over the back and sides of the body
Thinning over the ears
Thinning along the neck
Thinning under the belly
Complete hair loss along the sides
Circular bald patches
Baldness on the abdomen
Patches of baldness on the legs
Balding over the scrotum at the back of the hind legs
Hair loss is just one symptom of a medical problem; it can also be accompanied by changes in behavior or irritability, and your dog may become restless or lethargic. Common with hair loss is change in the skin. Your dog may suffer from redness or swelling, flaking, crusting, changes in color or discharge, along with an unpleasant odor from an infection.
