My dog has a squishy, growing lump near his penis. What should I do?
Thank you for providing pictures of Gucci's bump. From the pictures, it looks like it could be a cyst, a benign tumor, or a 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 the lump is diagnosed, the vet can discuss treatment options with you. Given that the lump is getting bigger, I would have him seen by a vet on Monday. Good luck, I hope this helps!
