What Are Sebaceous Cysts?
Sebaceous cysts are non-cancerous growths that develop from the sebaceous glands in the skin. These glands produce an oily substance called sebum, which helps to keep the skin and coat healthy. When a sebaceous gland becomes blocked, it can cause a cyst to form. Sebaceous cysts are typically round or oval in shape and can range in size from a few millimeters to several centimeters. They are usually soft and movable, and they may be filled with a white or yellow fluid.
What Causes Sebaceous Cysts in Dogs?
The exact cause of sebaceous cysts in dogs is unknown, but there are a number of factors that can contribute to their development, including:
- Hormonal imbalances
- Obesity
- Allergies
- Certain breeds (e.g., cocker spaniels, poodles, schnauzers)
Symptoms of Sebaceous Cysts in Dogs
The most common symptom of a sebaceous cyst is a lump or bump on the skin. These lumps may be located anywhere on the body, but they are most commonly found on the head, neck, and trunk. Sebaceous cysts are typically slow-growing, and they may not cause any discomfort to your dog. However, if the cyst becomes infected, it may become red, swollen, and painful.
Diagnosis of Sebaceous Cysts in Dogs
Your veterinarian will be able to diagnose a sebaceous cyst based on a physical examination of your dog. In some cases, your veterinarian may recommend a fine needle aspiration (FNA) to confirm the diagnosis. FNA is a procedure in which a small sample of cells is removed from the cyst and examined under a microscope.
Treatment of Sebaceous Cysts in Dogs
The treatment of sebaceous cysts in dogs will depend on the size, location, and severity of the cyst. In most cases, treatment is not necessary. However, if the cyst is causing discomfort or if it becomes infected, your veterinarian may recommend one of the following treatments:
- Surgical removal
- Laser therapy
- Cryotherapy
- Topical antibiotics
Prevention of Sebaceous Cysts in Dogs
There is no surefire way to prevent sebaceous cysts in dogs, but there are a few things you can do to reduce the risk of your dog developing these growths:
- Keep your dog at a healthy weight. Obesity is a risk factor for sebaceous cysts.
- Control your dog's allergies. Allergies can trigger inflammation in the skin, which can lead to the development of sebaceous cysts.
- Brush your dog's coat regularly. This will help to remove dead skin cells and prevent the sebaceous glands from becoming blocked.
