Hair loss, also called alopecia, is a fairly common condition in pets. It can affect dogs and cats of all ages, breed and gender, and can be either gradual or acute. It is a very noticeable condition characterized by a variety of different hair loss patterns, from total hair loss to bald circles of hair loss. There may also be some scaling of the skin around the affected area.
One of the most common causes of hair loss is demodicosis (mange), which is a common skin condition caused by the Demodex mite. Other causes include infection, trauma, immune issues, and endocrine system abnormalities.
Treatment is dependent on the cause. If the cause is a separate underlining health concern, like mange, that issue must be treated first. Otherwise, hair loss is usually treated with topical shampoos and antibiotic therapy.
There is little that can be done to prepare for or prevent hair loss in a pet, but it is critical for pet owners to monitor their pets for any sign of hair loss and visit a veterinarian if any signs are noticed.
