Young dogs get benign tumors called histiocytomas. These usually grow quickly, but the immune system will typically resolve the problem within a month or so. However, if the lump is still there in a month or so then I would be a good idea to have him evaluated by your veterinarian. Best of luck and thank you for using Pet Coach.
