My senior dog has a small pink growth on her inner thigh. What is it?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 11 years and 4 months old | 50 lbs

I noticed today that my 11 year old 50lb mixed breed female dog has a pink growth, in the inner thigh region right where the leg joins the body. The attached picture isn't the best but is the only one she will let me take, I don't think she's in pain she just doesn't like to be grabbed. The growth is roughly the size of half a penny, hairless, smooth, and firm but not solid to the touch. What could it be?

This growth could be benign or 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. Give Momo's vet a call in the morning to make her an appointment.

My dog has a small pink growth on her face. See attached photo. Any thoughts on what this could be?
It looks like it could be a benign growth, but without seeing her in person, I can't say for certain. Any suspicious lumps should be examined by the vet.

My dog has a lump on her leg roughly the size of a marble. She is a 9 year old cocker spaniel and is very healthy otherwise.
Thank you for providing a picture of Mia's lump! It could be a benign tumor, a cyst, or a malignant tumor. Unfortunately in a senior dog, there is always a chance it 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 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 her into the vet in the next couple of days to have this lump examined and diagnosed so it can be treated as needed. Good luck, I hope this helps!

Any advice on this pink cauliflower type lump i just discovered on my 14 year old, long haired English terrier x he is limping slightly on his front right paw, and he just lost his best mate to bone cancer this week
This usually a completely benign lump that is commonly found on old dogs. It is usually harmless unless bleeding or infected (it does not look like it in the pic). Unfortunately this kind of lump/growth needs to be ideally assessed by your veterinarian to have a 100% 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). Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

My dog has a growth on her belly. It's been there for years. Recently it has started growing really fast. She is almost 12 years old. What could it be?
This growth on your dog could be a benign tumor or a malignant tumor. Any suspicious growth should be examined by a vet. The vet can do a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the growth to get a sample of its cells, and examines the cells on a slide under a microscope. It's typically painless to the dog and relatively quick and easy to perform. I would have your dog seen by a vet on Monday to have the growth examined and diagnoses so it can be treated.

At Destiny's age, I would be concerned this could be a malignant tumor and it's concerning how big it is. Any suspicious lumps should be examined by the vet.

Best of luck.

I rescued a dog,female approx 10 years old.She has a red soft growth on her leg/paw area.She also has the same type of growth in her eye area.Any idea what it could be? It is red and spongey
This could be a benign skin mass like a wart or a lipoma or could be something more serious like a mast cell tumor. My best recommendation is to take Mara to the veterinarian so a fine needle aspirate and cytology can be performed. This will help your veterinarian determine the cell type of origin and decide if the masses need to be removed. I hope this helps. Thanks for using Boop by Petco. Best of luck.

My 11 yo chi terrier has this on his leg, thought was tick but took photo and looks like mole?
That's an interesting looking growth, it looks almost purplish in the photo. In a dog Huey's age, any growth has a chance to be malignant. Any suspicious lumps should be examined by the vet.

My dog has a pink wart type of growth on her shoulder but I see a black spot on it and want to know if it needs to be examined.
Any suspicious lumps should be examined by the vet. This lump on Ophelia could be caused by a wart, but it could also be due to a benign tumor or a malignant tumor. 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 have Ophelia seen by a vet on Monday or Tuesday to have this lump examined and diagnosed so it can be treated as needed.

Dog developed lump on hip that was light pink and hairless, a few months have gone buy and it has gotten a little bigger on the outside but a good size bigger underneath the skin. Doesn’t seem to bother her
This looks like a tumor. You need to make an appointment with your veterinarian to have this mass examined and preferably have a Fine Needle Aspirate done to send to a laboratory or have it removed right away if possible, in case it is a malignant growth. The FNA will help with diagnosing whether this is malignant or benign.
