Hair loss, also known as alopecia, is a condition characterized by complete or partial loss of hair. It is common in dogs and cats and can be caused by a wide range of underlying health conditions.
Causes of Hair Loss
Some of the most common causes of hair loss in pets include parasites, skin infections, and allergies. Other factors linked to the development of the condition include trauma to the skin, nutritional imbalances, genetics, and hormonal problems. Hair loss in pets can also be a symptom of behavioral issues such as separation anxiety and excessive grooming.
Symptoms of Hair Loss
Please visit your veterinarian if your pet displays any of the following signs or symptoms of hair loss.
- Itchy or inflamed skin
- Bald patches
- Crusting
- Scaling of the skin
- Ulcers or open wounds
- Oozing or bleeding skin
- Hot spots
- Lethargy
Diagnosis of Hair Loss
Your veterinarian will assess your pet’s medical history and ask you a series of questions about the onset and severity of their symptoms. They will then perform a complete physical examination to check for clinical signs of hair loss. Often, the pattern of hair loss will help your veterinarian to identify its potential cause.
Other diagnostic tests that can be used to determine the underlying cause of hair loss include a urinalysis, bloodwork, skin biopsies, and fecal examinations. Imaging techniques such as X-rays and ultrasounds may also be performed to check for underlying health issues that may be contributing to the condition.
In addition, your veterinarian may recommend allergy testing or other specialized tests to help identify the cause of hair loss.
Treatment of Hair Loss
Treatment of hair loss will depend on its underlying cause. Common treatments include topical or oral medications such as antibiotics, antifungal drugs, and steroids to address infection and reduce inflammation. If your pet is suffering from allergies, antihistamines will often be prescribed to minimize symptoms.
Other potential treatments for hair loss include medications to modify compulsive behavior, vitamin supplementation, and dietary changes to correct nutritional imbalances, and pest preventatives to eliminate parasites. Please speak to your veterinarian about appropriate treatment options for your pet.
Prevention of Hair Loss
Since there are so many potential underlying causes of hair loss in pets, the condition can be difficult to prevent. We recommend feeding a complete and balanced diet, protecting your pet against parasites, and providing mental stimulation to prevent destructive behaviors. Please consult with your veterinarian for more information about preventing hair loss in pets.
