Thank you for posting the picture. It is really helpful. This lesion could be many things, and an examination with a veterinarian would be the first step toward a diagnosis and treatment plan. In my experience lesions such as this one in a young dog are usually either a histiocytoma, eosinophilic furunculosis, or ringworm. All of these can pop up quickly, and they are all treated differently. A histiocytoma is a benign tumor that will usually resolve within 4-6 weeks. The others need medications. A veterinarian can do a needle aspirate to help make the diagnosis and determine what the best treatment plan should be. Best of luck and I hope Tank improves soon. Thank you for using Pet Coach.
