What should I do about a white skin bump under my senior dog's arm?

Hi there. That appears to be just a benign wart or cyst. I would not worry about it at all. Just monitor it and if it starts to change in color, shape, size or it starts to bother Terry then you should get him to your vet for an exam. I don't expect that will happen. Hope this helps. Best wishes.

There are numerous causes of lumps on a dog Sheba's age, and not all are worrisome. Dogs can develop non-cancerous lumps like cysts, seromas (pockets of fluid), abscesses, and bruises. Some of these can go away after being drained by a veterinarian. Dogs can also develop lipomas, which are benign fatty tumors, that generally do not cause problems. Some owners elect to remove them and some monitor them at home. The best way to figure out what is going on is to take Sheba in to have your vet examine her and possibly do a fine needle aspirate of this lump, which involves sticking a small needle into the lump and trying to remove cells/fluid. These cells/fluid can then be examined under the microscope to help determine what the lump is made of and how it needs to be treated.

It sounds like this is some kind of skin growth. Dogs can develop melanomas of the skin along with many other benign growths. I would recommend having your vet take a look - they might recommend taking a sample with a small needle to determine what this might be, or they might recommend going ahead and removing it.

This may be a little abscess, a cyst or a tumor (warts are benign tumors, btw.). You should have it examined by your veterinarian, as it is not possible to distinguish these by just looking at a photo. An abscess can usually be treated with antibiotics and/or be lanced, and a cyst can be evacuated. To identify a tumor, your vet may want to do a fine needle aspirate (he takes some material from the bump with a needle and then looks at it under the microscope) to determine whether the mass is concerning.

This growths on Teddy could be benign, but in a senior dog, there is always a chance that they would 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'd give your vet a call to make an appointment to have these growths examined and diagnosed so they can be treated if needed. Best of luck, I hope this helps.

Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign growth or a malignant growth such as a mast cell tumor, melanoma, among many other possibilities. I recommend you have Houdini evaluated by your veterinarian for a test called fine needle aspirate which is an easy, quick and pain-free procedure which in the majority of cases will help reach a diagnosis to identify what the best course of action is based on the findings. In some cases, a biopsy is needed for a diagnosis. If it truly is benign then removal is not necessarily recommended. However, if it is malignant and it has not spread to other locations, then surgical removal is recommended. Good luck! Keeping my fingers crossed that it is something benign.

Thank you for the image. This is likely a benign skin mass known as a sebaceous adenoma. They are common in older dogs and arise from sebaceous glands in the skin. You would need to have your dog physically examined by your veterinarian for confirmation. Removal is recommended if the lump grows larger or becomes ulcerated, but others may grow in the same spot or different areas. Keep it clean and dry and be careful not to irritate it during grooming/brushing or bathing.
