That looks like a lump on Gurgi, and it could be a cyst, abscess, lipoma, benign tumor, or malignant tumor. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of lump is diagnosed, the vet can discuss treatment options with you. I would give his vet a call tomorrow to make him an appointment. Best of luck.
