Suggestions for Treating a Cyst on a Dog Belly

Hi Lsura,

A raised, oval, reddish cyst on a dog's belly could potentially be a sebaceous cyst, among other things. Here are a few possibilities:

Sebaceous Cysts (also called "keratin inclusion cyst,” “follicular cyst,” or “epidermal inclusion cyst”): These are the most common types of skin cysts in dogs, caused by blocked sebaceous glands. Sebaceous glands produce sebum, an oil that moisturizes the skin and coat. When they become blocked, they fill with this sebum and can appear as a lump or cyst. They are usually benign (non-cancerous), but they can become inflamed or infected.

Here are some potential treatments for a sebaceous cyst if that is the cause of the problem:

Monitor the Cyst: If the cyst is small, not causing any discomfort or complications, and the dog is not bothering it, your vet may suggest a "wait and see" approach. Sometimes, these cysts can rupture and drain on their own.

Warm Compresses: Applying a warm compress to the area can help encourage the cyst to drain. However, you should never attempt to squeeze or pop the cyst yourself, as this can lead to infection.

Topical Treatments: There may be some topical treatments your vet can recommend to help manage the cyst.

Cyst Removal: If the cyst is large, causing discomfort, or becoming a problem, your vet may recommend surgical removal. This is typically a simple procedure, but like all surgeries, it does carry some risk.

Antibiotics: If the cyst becomes infected, your dog may need a course of antibiotics.

Corticosteroids: In some cases, a vet may inject the cyst with a corticosteroid to reduce inflammation.

It's important to remember that while these treatments can manage a sebaceous cyst, they do not treat the underlying cause, which is the blocked sebaceous gland. Your vet can help you understand why your dog is prone to these cysts and discuss potential strategies for prevention.

Here's some other possible causes if a sebaceous cyst is ruled out by your veterinarian:

Lipomas: These are benign fatty tumors, common in older or overweight dogs. They are usually soft, round, or oval, and located just under the skin. They can vary in size and are often movable when touched.

Histiocytomas: These are common in younger dogs, and appear as small, raised, red lumps. They are usually benign and often disappear on their own over time.

Mast Cell Tumors: These are a type of skin cancer in dogs. They can vary greatly in appearance and can look like just about any kind of lump or bump, including a reddish, raised cyst.

Insect Bites or Stings: An insect bite or sting can cause a raised, red bump on a dog's skin. These usually improve on their own over time but may require treatment if the dog is allergic.

Allergic Reactions: Dogs can have allergic reactions to a variety of substances, such as certain types of grass, pollen, food, or medications. These reactions can cause skin changes, including red, raised bumps or lumps.

Abscesses: These are pockets of infection that can form under the skin. They are usually painful and may feel warm to the touch.

We always suggest that you consult with a veterinarian if you notice any unusual lumps or bumps on your dog. The vet can do a physical exam and may perform tests such as a fine needle aspirate or biopsy to determine the cause of the cyst. In some cases, removal and histopathology (microscopic examination) may be required to confirm the diagnosis.

Please keep us up to date on your dog's condition.
