Thank you for submitting your question regarding Yote. I would definitely ask your veterinarian about the new bump at the appointment. A procedure known as a fine needle aspirate will likely need to be performed. The veterinarian will use a small needle to collect a sample of cells to evaluate under the microscope. This will hopefully give a diagnosis for the mass. A histiocytoma is a benign growth that is common in young dogs. Unfortunately, a mast cell tumor is an aggressive form of skin cancer and has the same outward appearance. I hope this information helps!

If your dog is less than two years old, I am suspicious of a histiocytoma which is a benign tumor that will go away on its own within a few months. If he is older than 2 years old, it could be a papilloma (wart). If they spread or multiply, see a veterinarian for a more accurate diagnosis and treatment. Best of luck to you and Motivate!

I recommend to have Junior examined by the veterinarian. Skin masses can be many things but red raised masses are especially concerning for a skin cancer called a Mast Cell tumor. Your veterinarian will need to collect a sample of cell to examine under the microscope to determine what this is and if further treatment is needed. Have this checked out soon.

That looks like a viral papilloma to me. Papillomas are benign and tend to go away on their own. However, it is impossible to diagnose a growth on just a picture alone so if the growth gets larger or gets irritated it's worth having your veterinarian look at it up close.
