My dog has a red lump with a hole on his paw. Should I worry?

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. There is no way of knowing what it is just based on its appearance. Common tumors in this region include melanomas, squamous cell carcinomas, mast cell tumors and soft tissue sarcomas, among others. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good night!

This isn’t a pimple. It is a small mass in the top layer of the skin. It could be a cyst, a wart, or a benign or cancerous growth. The only way to know for sure is to have your vet collect a sample with a needle to examine under a slide or to remove the whole mass and send it to the lab for evaluation. Until that happens, you can watch it for changes in size, color, texture, etc. If you notice any changes, I would call your vet to see if they can get you in sooner.

It looks a little red and inflamed so it could be an infection. You could soak his paw in a warm Epsom salt solution and see if that helps. Otherwise, have your vet take a look at him as he may need an antibiotic to treat the infection.

Any lumps/bumps that you notice on your dog should be checked out by your vet. Lumps can be any of these things: * abscess (infection) * cyst * cancer (benign or malignant) * wart There is no way I can tell you for sure what it is just based on your description or by looking at a photo but I have a suspicion that this may be a histiocytoma (benign tumor).

Your picture came through. Romeo has a major mass that is ulcerated and looks to be infected. He needs to see a vet right away for proper wound management, pain medication and antibiotics. This is a massive mass that cannot be managed at home without the help of your local vet. Once the infection is controlled then it can be discussed whether this mass can be debulked or not. If it cannot then your vet may recommend amputation of the leg. I am sorry your pet has such a massive tumor and I hope everything works out ok for your pet Romeo. Best wishes and take care.

I'm glad to hear that this lesion isn't bothering Benji! It's certainly possible that this lesion is a benign papilloma-like lesion, but it could also be another benign or malignant type of mass. The only way to know for sure is to perform a biopsy of the lesion for pathologist evaluation, or at the very least, your vet could draw a few cells out with a needle for microscopic evaluation (fine needle aspiration). The tricky part with lumps and bumps on legs is that they're more difficult to remove if they grow because there is less extra skin that can be used to close surgically. For this reason in particular, I recommend taking Benji to your vet sooner rather than later to have this lesion examined in person. Even though he isn't bothered by the lesion when you touch it, I do recommend putting an e-collar (cone) on him until his appointment because the lesion looks a bit red and weepy. This can occur if he's been licking at it, even if you haven't seen him do so. I hope that he's on the mend soon!

Thank you for submitting your question regarding Bruno. I recommend that he sees his veterinarian. He may need a procedure known as a fine needle aspirate to diagnose the mass. The veterinarian will use a small needle to collect a sample of cells to evaluate under the microscope. This will help to determine the type of mass and guide treatment. A histiocytoma is a common mass on the limb of a young dog. This is a benign growth. However, the outward appearance is the same as a cancerous growth known as a mast cell tumor. In the meantime, place an E-collar on him so that he does not cause any self-trauma. I hope this information helps!
