Lipomas in Dogs and Cats: Causes, Symptoms, and Treatment

What is a lipoma?

Lipomas, commonly known as fatty tumors, are benign growths that develop underneath the skin in dogs and cats. While they are usually harmless, their presence can cause concern for pet owners. Understanding lipomas, including their causes, symptoms, and treatment options, is essential for ensuring the health and well-being of our furry companions.

What are Lipomas?

Lipomas are soft, movable masses that typically develop in the subcutaneous tissue, which is the layer of tissue just beneath the skin. These growths consist of fat cells and often feel like rubbery lumps under the skin. Lipomas can vary in size from small pea-sized nodules to larger masses that can grow several inches in diameter.

Causes of Lipomas

The exact cause of lipomas in dogs and cats is not fully understood. However, several factors may contribute to their development:

  1. Genetics: Certain breeds, such as Labrador Retrievers, Doberman Pinschers, and Dachshunds, are more prone to developing lipomas.

  2. Age: Lipomas are more common in older pets, typically appearing in dogs and cats around middle age or older.

  3. Obesity: Overweight or obese pets may have a higher risk of developing lipomas, as excess fat tissue can contribute to their formation.

  4. Hormonal Imbalance: Hormonal changes or imbalances may play a role in the development of lipomas, although more research is needed in this area.

Symptoms of Lipomas

In many cases, lipomas do not cause any symptoms and are often discovered during routine physical examinations by a veterinarian. However, some pets may exhibit the following signs:

  1. Visible Lumps: Owners may notice soft, round lumps beneath the skin, which can vary in size and number.

  2. Limping or Discomfort: If a lipoma grows large enough to press on nearby nerves or tissues, it may cause limping or discomfort in affected pets.

  3. Changes in Mobility: Pets with lipomas located in areas that interfere with movement, such as the limbs or torso, may exhibit changes in mobility or range of motion.

Diagnosis and Treatment

To diagnose a lipoma, a veterinarian will perform a physical examination and may recommend additional tests, such as fine needle aspiration or biopsy, to confirm the diagnosis and rule out other potential causes.

In most cases, treatment for lipomas in dogs and cats is not necessary unless they are causing discomfort or interfering with the pet’s quality of life. However, if a lipoma is large, rapidly growing, or causing other health problems, surgical removal may be recommended.

During surgery, the veterinarian will remove the lipoma along with a margin of healthy tissue to prevent recurrence. In some cases, liposuction may be used as a less invasive method of removal.

Preventative Measures

While it may not be possible to prevent lipomas entirely, there are steps pet owners can take to help reduce the risk of their development:

  1. Maintain a Healthy Weight: Keeping pets at a healthy weight through proper diet and regular exercise can help prevent the accumulation of excess fat tissue.

  2. Regular Veterinary Examinations: Routine veterinary check-ups can help detect lipomas early and monitor their growth over time.

  3. Monitor for Changes: Pet owners should regularly check their pets for any new lumps or bumps and report any changes to their veterinarian promptly.



Lipomas are common benign growths that can develop in dogs and cats, particularly as they age. While they are usually harmless, it’s essential for pet owners to be aware of the signs and symptoms associated with lipomas and to seek veterinary care if any concerns arise. With proper diagnosis and management, pets with lipomas can lead happy and healthy lives.
