My Boxer has a firm, painless bump on his leg. What is this growth?

Updated on September 23, 2025

Pet's info: Dog | Boxer | Female | spayed | 8 years and 9 months old

Hi there, recently I noticed a a bump about the size of a large grape on my boxer dogs front left leg. It looks a little bit like a boil but it doesn't feel 'squishy'. When i pressed down on it my dog didn't flinch or move so it doesn't seem to be particularly painful. There is hair and fur growing through it it seems. Do you know what this is or how it couldn't be treated? Thank you very much

This could be from an injured, a benign growth, or a malignant growth. Without seeing Kes in person, I can't say for certain. I think it should be checked out by a vet, and depending on what the cause is, the vet will discuss treatment options.

Thank you for contacting Pet Coach with your question about Kiara! In Boxers, mast cell tumors are common and it's possible this could be a mast cell tumor. It could also be another type of tumor, malignant or benign. Given that it has double in size, she should see a vet first thing Monday. 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. Once the cause of this lump is diagnosed, the vet can discuss treatment plans with you. Good luck, I hope this helps!

My Boxer has a red bump on her inner front leg. What could it be?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! A lot if skin bumps can look the same. But for a young dog and the location of it being on a leg it is likely a benign growth called a histiocytoma. They usually spontaneously regress in a few months. The other possibility is a Mast cell tumor, which can be common in Boxers. If the bump grows larger or doesn't go away in 2-3 months I would have your Vet examine it and consider aspirating it to see what it could be. It is never wrong to get it looked at sooner either! I hope this helps!

Why does my Boxer have a new, non-red bump on his stomach area?

Hello If possible a photograph of this lump would be helpful. It could be a lipoma (a harmless fatty tumor) but Boxers are known for developing mast cell tumors on their skin. Those types of tumors need to be removed as they can cause issues with the GI tract and even anaphylactic reactions.

Why does my dog's leg bump grow when squeezed, then shrink?

It could be that Zeke has a cyst or a benign tumor causing this bump, and I would not squeeze it anymore. Instead, I would have him seen by a 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 bump 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 have him seen by a vet in the next couple of days to have this bump examined and diagnosed so it can be treated as needed.

My Boxer has a black raised growth on its jaw. Should I worry?

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'd give Lilly's vet a call in the morning to make her an appointment.

My dog has a hard bump on his leg. Why is he scratching and licking?

I can see the round, raised bump you are referring to. This can be a small growth, allergic reaction, bug bite, or a sign of a skin infection. I recommend having Kane seen by a vet, as this is clearly making him uncomfortable. Your vet can take a small sample with a small needle to determine exactly what is going on and rule out the conditions above. In the meantime, you can get Kane an E-collar or "cone" to prevent him from licking the area and making it worse.

My Boxer has a bump on her mouth. What is it? Should I worry?

I'm sorry to hear Molly has a growth. I would recommend she be seen by her regular veterinarian. Boxers are predisposed to a type of skin cancer known as a mast cell tumor. Your regular veterinarian should be able to determine with a needle aspirate if this bump is a mast cell tumor or not, and the necessary next steps to take. As they are curative if caught and removed early, I would recommend she be seen as soon as you can to determine if it is a problem for her or not. Good luck!

My Boxer has a swollen red head bump and hazy eye. What's wrong?

Boxers are very prone to skin and other forms of cancer. While this looks well defined I recommend a veterinary exam and possibly a biopsy to see if it’s cancer. They can remove the bump and check her eyes and the other skin mass at the same time. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Diamond.
