My old dog has a fatty lump. Is it a lipoma or something worse?

Updated On September 23rd, 2025

Pet's info: Dog | Jack Russell Terrier | Male | unneutered | 16 years and 2 months old | 17 lbs

(see previous) Patch is c. 15yo JR terrier who has non-malignant growths on his coat (chest, flank, head). Taken him (twice) to veterinarians/ prescribed meds. Now, one area (lump) left flank, had gone, now re-appeared, spread over area covers (size of a saucer). Hard skin, seems fatty. No pain, active, bounces up+off couch, eats+drinks well, stools ok. Am I paranoid? I am scared 'they' will put him down or suggest an op'.

Lipomas can be very common in dogs, and if the lump feels fatty, it may simply be a lipoma. It seems he has a history of non-malignant growths, and due to that, it may be most likely he has another non-malignant growth. Unfortunately only by seeing a vet can you know for sure, and I do recommend having it done. Given that he is acting otherwise normal, there would be no reason why they would put him down and certainly they couldn't do that without your permission. As for an op, they can suggest it if they feel it may help him, but it's your choice as to whether or not the op is performed. I can tell you are very worried about Patch, but don't let that get in the way of having this lump checked out. I'd have him seen by a vet on Monday. I hope this helps!

MY 10 YEAR OLD SHIH TZU HAS A LARGE LUMP THE SIZE OF A GOLF BALL HANGING UNDER HIS NECK. IT HAS WENT AWAY AND NOW HAS COME BACK. EVERY ONE KEEPS SAYING THAT IT IS JUST A FATTY TUMOR BUT I AM NOT CONVINCED. HE ACTS LIKE NOTHING IS WRONG AND EATS LIKE
Yes, I would be concerned. Without seeing a vet, you can't know for sure if this lump is a lipoma. In a 10 year old dog, there is always a concern that any lump could be malignant. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. I would call the vet today to make an appointment for him to be seen. I hope this helps!

Recently felt pea-sizes lumps of what seemed to be fat just under his skin in the chest and stomach area. No history of growths, tumors, or cancer...
You are correct these lumps could be lipomas (benign fatty tumors), but they could also be cysts, benign tumors, or malignant tumors. In senior dogs, cancer is always a possibility, and I would recommend having Mickey seen by a vet to have the lumps diagnosed. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. I would take him into the vet in the next couple of days to have the lumps diagnosed and treated if needed (lipomas typically need no treatment).

A few months ago I took my dog to the vet to get a lump on her neck checked out. The vet took a sample and said it was just a fatty lump. Since then its gotten bigger (from "Large-egg sized" to around about 50% bigger). It hasn't started to cover any
Fatty lumps (lipomas) can grow up to considerable size without causing any problem, but in rare cases can turn into malignant masses (liposarcomas). A clinical examination at your local veterinarian is essential torule out this clinical suspicion. Another sampling may be needed.

Does my dog have a tumor? What is this lump?
Thank you for your question. Most commonly, something like this would be a lipoma, which is a fatty tumor, but I can't make that diagnosis on just a picture. Many dogs get lipomas, and they are typically not a problem, however, they can grow and become very annoying to the dog. This lump could also be a hernia, an abscess, or another type of tumor. The only way to know for sure would be to have a veterinarian feel the lump and use a needle to obtain cells to identify under a microscope. This is called a fine needle aspirate, and it is the procedure vets use to identify all sorts of lumps. I hope this helps.

My black lab cross blue healer is about 10 years old now and he had a fat lump on his chest and we had it checked out and he was ok and it went away but now he has another fat lump on his back by his ribs, should this also be a big concern?
Even though it is likely to be another lipoma (benign lump)this kind of lump/growth needs to be ideally assessed by your veterinarian to have a definitive and specific answer. Usually there are two ways your vet can do that a part from examining it directly during physical examination. A biopsy can be taken under local or general anesthetic, otherwise a smaller sample through a fine needle can be aspirated (this technique is called FNA= fine needle aspiration). Differentials include skin cysts, infections, benign or more sinister type of tumors. Please do not hesitate to contact us again on the forum or by requesting a consultation (where you can post pictures ) if you have any more questions or to discuss it any further.

Golden retriever has a fatty lipoma on left rib the size of 1/2 a basketball for last 2 years...stayed close to same size...aspiration a couple no ths ago said fat cells...no cancer detected...can cancer still be in it? Can it be drained? What can I
Lipomas can unfortunately get this big; and if they don't grow, become more firm or attached, or hinder the mobility of the pet removal may not be recommended. Typically most lipomas can be diagnosed with the test your family performed, a needle aspiration. But, sometimes I do see patients that develop a secondary tumor type within the lipoma. So it is important to periodically palpate the mass to make sure it's not changing in texture, firmness, or causing any discomfort to the pet. An xray of the area is also helpful to assess whether the mass is purely a fat density or if it may contain different tissue density that is more concerning. There are also some tumors that can masquerade as lipomas and may not be readily diagnosed with the needle cytology. If there is a suspicion of this scenario then some pets undergo a small biopsy. Unfortunately the only way to fully remove a lipoma is with surgery, although this can typically be more of a conserative surgery as these masses are benign

I just felt a lump on my dog's side on his ribcage area when he bent his body to lean into me and I was petting him. It appears to be soft and squishy but under the skin/not felt super easily. He is a 9 year-old, about 60 lb husky mix (we think). I'm
I certainly understand being worried about Beckett! If the lump feels soft and squishy, it could be a lipoma. This is a benign fatty tumor. It could also be a cyst, another type of benign tumor, or a malignant tumor. Unfortunately in older dogs, there is always a chance a lump would be malignant. Having him seen by a vet is the best idea. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. Best of luck, I hope this helps!

I found a lump, it doesn't hurt him to have it touched. It's not really soft nor does it move. He is walking, eat, drinking, and behaving normally. He got bit by a dog on the inside of the same leg a year ago but the lump is on the outside. Should I
This can be a benign lump, or it could be a lipoma or cyst. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it.

I'd give his vet a call tomorrow to make him an appointment. Best of luck.

Teddy has been licking his paws a lot, seems disoriented and whines a lot. He acts happy when he comes back inside from potting but then will stand by our bedroom door and whine when we are in the same room and calling his name. Is he going blind or

I have an 8 year old cairn terrier and I have found 2 lumps on the side of his stomach, they are no bigger than a small thumb nail but he seems to be nibbling at one. Is this something to be concerned about? Thanks
Hello there from across the pond! Lumps and bumps on older dogs are fairly typical and are to be expected with an older pet. By and large, lumps and bumps that are round, smooth, and/or freely movable generally speaking are not causes for alarm. However, lumps and bumps that become red, inflamed, warm to the touch, itchy, have rough edges, are rapidly growing, or have discharge coming from them need to be looked at by a veterinarian and have them assessed. Regardless, I would recommend your veterinarian take a look at Chester and take small sample of the small mass he has and look at it under a microscope. From there, your vet can determine the nature of the mass and if it is concerning. You may also discuss surgical removal of the small mass if that is recommended by your vet. I hope this has helped!
