Thank you for submitting your question regarding Nacho. From your picture the skin mass appears to be red in color. If this is the case, I do recommend that he sees his veterinarian. A procedure known as a fine needle aspirate will likely be performed. The veterinarian will use a small needle to collect a sample of cells to evaluate under the microscope. This will help to diagnose the type of mass. There is a benign growth that is common in young dogs known as a histiocytoma. However, there is an aggressive type of skin cancer that has the same outward appearance. This is a called a mast cell tumor. The procedure is necessary to differentiate between the two and decide if treatment is necessary. I hope this information helps!
