What are these new spots on my puppy's back feet? Should I see a vet?

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. There is no way of knowing for sure without an examination though this represents a reason to seek veterinary care. This is usually determined with an examination and a fine needle aspirate (FNA) or a biopsy. Treatment depends on the findings up to that point. I recommend you have Reese evaluated by a veterinarian for further assessment and treatment. Good luck and have a good night!

Thanks for using Petco Pet Education Center, formerly Petcoach! These could potentially represent nodules or masses that have become ulcerated. They could also be just focal patches of dermatitis. I recommend that you have Bella evaluated by your veterinarian. This is most of the time differentiated with a test called a fine needle aspirate which is easy, cheap and pain-free. Sometimes, a biopsy is required for a diagnosis. Have Bella evaluated by your veterinarian to have this test performed to try to sort out what the diagnosis is so that the best course of action can be determined. If it does not appear to be a mass on examination, they can at least do cytology of the superficial aspect and see if infected and prescribe antibiotics for it. Keeping my fingers crossed that it is something benign!

Hello, and thank you for using PetCoach. I’m seeing a red, round, raised, hairless mass. This appearance would make me primarily suspicious of either a [histiocytoma](https://www.petcoach.co/dog/condition/histiocytoma/) or a [mast cell tumor](https://www.petcoach.co/dog/condition/mast-cell-tumors/). The only way to tell for sure what this lump is, is via cytology. Your vet will get a small sample of cells with a needle and examine them under a microscope to determine what the mass is. I definitely recommend having this done as soon as possible. A histiocytoma is a benign mass that tends to spontaneously resolve. A mast cell tumor would be a concern, and should be surgically removed as soon as possible. I hope this helps!

Hello, thank you for using PetCoach. This looks to be a histiocytoma tumor which is a benign tumor commonly found on the limbs and face of dogs. It is a benign tumor that usually will regress on its own within a few weeks/months with no treatment. Of course, I am just guessing. It is impossible to diagnose these things via the internet with just a photo. Here is an information sheet about histiocytomas in dogs for you to read. ( https://vcahospitals.com/know-your-pet/skin-cutaneous-histiocytoma ) He should not be licking the tumor - if he is, you need to get him a cone collar to wear to stop that behavior. If he is just licking the paw, that is not likely related to the tumor and is a different issue. As always, if you are worried, you should take him to your vet for an exam. Best wishes.

Hi there. This is most likely a histiocytoma. They will often regress on their own within a few weeks to a month. My suggestion would be to take Hazel to your vet for an exam so you can get a more definitive diagnosis. Here is a link to an article about this type of mass. http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=1676 Hope this helps. Best wishes.

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. 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 day!

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern! From the pictures you have provided, this appears to be what we call a sebaceous adenoma. This is a benign skin mass that we typically start to see develop in middle aged to older dogs. They do not cause any harm but can become sore and open from time to time. If these masses become infected or are painful I then recommend having them removed, otherwise, monitoring them is absolutely fine to do. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further!
