That does look to be a mass. A mass is a collection of cells and can be benign (inflammation, cyst, some tumors) or a malignant tumor. Given the age of your dog this may be a histiocytoma, but as many skin tumors can look alike the best plan to confirm this is for your vet to perform a needle aspirate for cytology. That way you will know for sure if this can be monitored or if it needs any therapy. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!

    Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. 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 her evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good night!

    It's hard to tell from the picture. You can try to clean it up a little and see what happens over the next couple of days. If you are concerned that it may be a mass, then I would recommend having Timber examined by a vet to determine what is going on.

    Thanks for using Petco Pet Education Center, formerly Petcoach! It is not possible to diagnose a mass just based on its appearance on a picture or a physical exam. It requires sampling and evaluation under the microscope. This could be a benign growth such as a sebaceous adenoma or a malignant growth such as a mast cell tumor, melanoma, among many other possibilities. I recommend you have Franklin 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.

    Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. This could even be an infection though it is hard to know without an exam. There is no way of knowing what it is just based on its appearance.
