Welcome to our complete guide to lipoma in dogs - Health advice from The Labrador Site.

What is Lipoma?

Lipoma is a benign, fatty-tissue tumor. This tumor is, in most cases, completely harmless.

Depending on the location, the tumor usually only presents a cosmetic issue, which doesn’t faze dogs one bit!

Because of this, lipoma usually doesn’t require treatment at all! Many dogs live long and happy lives with multiple lipoma tumors.

However, if the tumor is located in a problematic area, such as a joint or the throat, it might need to be removed.

Truthfully, lipomas aren’t a very rare occurrence in dogs. They seem to develop most commonly in overweight, female dogs. However, all dogs are at risk.

Furthermore, lipomas do not only appear in older dogs. The median age for a dog to develop a lipoma is six, which isn’t considered old at all!

Symptoms of Lipoma in Dogs

Usually, the only symptom of lipoma in dogs is noticing the actual lump beneath the skin.

Most lipomas are soft and slightly moveable under the skin. They feel like fatty masses beneath the dog’s skin.

Usually, your dog will not exhibit any signs of pain or immobility unless the tumor is located in a joint. Furthermore, this discomfort usually does not happen until the lipoma has reached a moderate size.

Most commonly, these lumps are located on the fattiest areas of the dog, such as the belly and trunk. However, they can appear everywhere and usually appear in increasing numbers.

A dog with one lipoma will probably develop another one eventually. This is not because lipomas are caused by a disease or are spreading around the body. It is simply that if a dog is genetically dispositioned to get one lipoma, they are likely to get another.

Causes of Lipoma in Dogs

The exact cause for these fatty growths is unknown.

It is assumed that some dogs are simply genetically dispositioned to develop them. Often times, it is noticed that if a dog’s parents had lipoma, they are also likely to get it.

However, like previously mentioned, overweight dogs are also more likely to get lipoma. Because of this, keeping your dog at a healthy weight can sometimes prevent a lipoma from forming.

Still, any dog can get lipoma, no matter their weight, breed, or gender. So ensuring that your pet is at a healthy weight will not always prevent these fatty tumors from forming.

Diagnosing Lipoma in Dogs

Diagnosis of lipoma is extremely important.

Just because your dog has something that appears to be lipoma, doesn’t mean he or she actually does.

There are various dangerous tumors that are similar to lipoma. It is important that these tumors get treatment right away. This is why it is always extremely important to get your dog diagnosed by a vet.

Often times, simply feeling the tumor is not enough to decide if it is simple lipoma or something more serious. On top of a complete physical exam, the vet will also need to extract some of the tumor with a fine needle. This small extraction can then be used to determine the type of tumor.

Usually, when a vet is physically examining a canine that is suspected to have lipoma, they find multiple masses. This is very common. However, each mass will need to be tested individually to ensure that they are all, in fact, lipoma.

If the fatty mass is in a joint or dangerous location, the vet might follow up the initial testing with a CT or MRI. These tests will allow for a better view of the tumor. This allows the vet to decide the best course of action in your pup’s care.

Infiltrative Lipoma in Dogs

Infiltrative lipoma in dogs is simply a special subclass of lipoma.

Instead of sitting harmlessly just under the skin, these tumors invade the muscle tissue and face of a dog. In other words, they literally grow into the muscles and surrounding tissue.

These lipoma are not always dangerous and sometimes do not cause any problems at all.

However, due to their tendency to invade and restrict a canine’s movement, they might need to be removed.

Dog Lipoma Treatment

Usually, a dog with lipoma doesn’t need to be treated at all.

Most lipomas are completely harmless and only cause cosmetic issues.

However, some lipomas might need to be removed based on location. These locations include places like the joints, neck, and spinal column.

In these cases, dogs often show other symptoms depending on the specific location.

For example, one study found that lipomas in the spine can cause paralysis. Another noted that a tumor near the trachea caused coughing and difficulty breathing.

In nearly all cases, a vet might recommend surgery to remove the mass. Luckily, these surgeries are often times very successful, with 67% of dogs remaining disease-free for at least a year after the surgery.

The success of the surgery depends partially on how defined the tumor is. Tumors that are more defined and separated from the surrounding tissue are easier to remove. Tumors that are in fatty areas of the dog, such as the stomach, are usually less defined than those located in joints and leaner areas.

Your vet might also recommend something like irradiation. This can be especially helpful if the tumor is difficult to remove or if the particular dog is known to redevelop these tumors quickly.

Dog Lipoma Removal Cost

If it is decided that your dog needs the lipoma removed, you can expect to pay somewhere around $300 to $500 dollars.

This also takes into account the probable aftercare your pet will need, such as pain management medications.

It is always important to ask your vet about the expected cost, however. Different vets charge different amounts and certain dogs are more likely to experience complications after surgery that might call for more aftercare.

Always ask your vet about your dog’s risk for complications, and prepare your wallet accordingly.

Lipoma in Dogs

Being told that your dog has a tumor can be scary. However, in most cases a lipoma is completely harmless.

In most cases, your vet probably will not recommend removal unless the mass is located in a dangerous location or is causing your pooch serious problems.

Usually, lipomas do not need any treatment at all and are left alone altogether.

However, it is still important to get your dog diagnosed by a professional. Some dangerous tumors feel like lipoma at first glance. This is why diagnosis is extremely important.

  1. Omg. I don’t even have a 100$. So he has to suffer this on top of all the old age stuff he’s going through. Idk if I can watch him go through anything else. He’s not ready to put down yet.

  2. Your cost estimates are a little off. Our dog is at the vet having lipoma surgery at this moment. CT scan to assess extent of lipoma -$1,200. Surgery – $2,800 – $3;800.
