Lipomas are common benign fatty tumours that typically affect older and overweight dogs. While most are harmless, some can grow large enough to affect comfort or mobility, and all new lumps should be checked by a veterinarian to rule out more serious conditions.

What Are Lipomas in Dogs?

What are lipomas in dogs? It can be alarming to find a lump under your dog’s skin. The good news is that not all lumps are dangerous. In fact, one of the most common types is the lipoma, a benign (non-cancerous) fatty tumour.

Lipomas are usually soft, round and movable under the skin. They’re most common in middle-aged and senior dogs, and they’re found more often in certain breeds like Labradors, Dobermans and Weimaraners.

While lipomas are typically harmless, it’s important to understand what causes lipomas in dogs, when to worry, and how you can support your dog’s health if they develop one.

Are Lipomas Dangerous?

Most lipomas are not dangerous. They’re considered benign growths, meaning they don’t spread or invade other tissues. Many dogs live happily with lipomas for years.

However, there are exceptions. For instance, large lipomas can interfere with mobility if they grow in awkward spots, like the armpit or chest. Multiple lipomas can also become uncomfortable as they increase in size. Plus, in rare cases, what looks like a lipoma could actually be a malignant tumour (such as a liposarcoma or mast cell tumour).

That’s why every lump should be checked by your vet. They can perform a simple test (fine-needle aspiration) to confirm whether it’s a benign lipoma or something that requires treatment.

What Causes Lipomas in Dogs?

The exact cause of lipomas in dogs is still not fully understood. However, vets and researchers believe several factors may increase the likelihood of these fatty growths developing. In many cases, it’s likely a combination of genetics, age, lifestyle and overall health.

Age

Lipomas are far more common in middle-aged and senior dogs. As dogs age, their metabolism, cell repair processes and immune function naturally slow down

This can make it easier for fatty tissue to grow in an unregulated way, leading to soft lumps beneath the skin. Older dogs are also more likely to experience changes in weight and activity levels, which may further contribute to fat accumulation.

Genetics

Some dogs appear to be genetically predisposed to lipomas. Certain breeds develop them more frequently than others, suggesting that inherited factors can influence how fat cells grow and behave.

Breeds commonly associated with lipomas include Labrador Retrievers, Golden Retrievers, Doberman Pinschers, Miniature Schnauzers and Cocker Spaniels. Dogs with a family history of lipomas may also be more likely to develop multiple lumps over time.

Weight

Overweight and obese dogs are often considered more prone to lipomas. Excess body fat may increase the chances of fatty tumours forming, particularly in dogs that have poor diet quality or limited exercise. 

While lipomas can still occur in lean dogs, maintaining a healthy weight may help reduce unnecessary fat storage and support better overall metabolic health. Regular exercise and balanced nutrition are important for keeping body fat levels under control.

Immune Function

A weakened or imbalanced immune system may also play a role. The immune system helps regulate cell activity and remove abnormal cells from the body.

When immune health is compromised due to ageing, illness, chronic inflammation or poor nutrition, abnormal fatty tissue may be more likely to develop unchecked. Although more research is needed, some holistic veterinarians believe supporting immune health can be beneficial for dogs prone to recurring lipomas.

Toxins & Environment

Some researchers and holistic practitioners suggest that environmental toxins may contribute to lipoma development. The theory is that toxins from processed foods, chemicals, pollution or household products may accumulate in fatty tissue over time. 

Because fat cells can store toxins, some believe the body may create fatty lumps as a way of isolating unwanted substances. Scientific evidence on this is still limited, but reducing unnecessary chemical exposure and feeding a high-quality diet may help support long-term health.

How Are Lipomas Treated?

There isn’t a “one-size-fits-all” treatment for lipomas in dogs. Options on how to treat lipomas in dogs depend on the size, location and how much the lump affects your dog.

Monitoring

Many vets recommend simply keeping an eye on the lipoma if it’s small and not causing problems. Your dog might also need regular check-ups to see if it is shrinking or to ensure it isn’t growing too quickly.

Surgical Removal

If a lipoma grows very large or interferes with movement, surgery may be recommended. This is usually a straightforward procedure, but as with any surgery, it comes with risks (especially in older dogs).

Lifestyle Adjustments

If you’re wondering how to reduce lipomas in dogs, maintaining a healthy weight through diet and exercise can sometimes slow lipoma growth.

Some owners also notice improvements when switching to a higher-quality, low-carb diet. Plus, you could add supplements like Turkey Tail Mushroom to their diet.

Supporting Dogs With Lipomas Naturally

With a better understanding of what are lipomas in dogs, you might want to find out how to help dogs with these issues. While lipomas themselves are typically harmless, their presence often makes owners wonder: Is my dog as healthy as they could be?

This is where supportive care comes in. You can’t always prevent lipomas, but you can help your dog by focusing on:

  • A balanced diet: Reduce unnecessary carbs and fillers, and choose nutrient-dense foods.

  • Regular exercise: Help your pet maintain a healthy weight and circulation.

  • Immune support: Strong immunity helps the body handle abnormal cell growth.

  • Gut health: A well-functioning digestive system aids in detoxification.

Turkey Tail Mushroom - Gentle Support for Dogs With Lumps and Bumps

One of the most researched natural supplements for dogs is Turkey Tail mushroom (Trametes versicolor).

While it doesn’t “cure” lipomas, it does provide important benefits for dogs dealing with lumps and bumps:

  • Immune modulation: Turkey Tail’s beta-glucans help the immune system function optimally.

  • Anti-inflammatory properties: It may help reduce the chronic inflammation linked to many health issues.

  • Gut support: With probiotics, digestion and nutrient absorption can improve.

  • Backed by veterinary studies: Clinical trials have shown Turkey Tail supports dogs with serious health challenges, making it one of the most trusted mushrooms in veterinary research.

Many owners use Turkey Tail for lipomas in dogs, not as a “lipoma treatment,” but as a way to support their dog’s overall health as they age.
