Hi! My dog is 8 years old and he has developed this little ball on his side over the last few mounths. Can you maybe let me know what it is and if it should be treated in any certain way? Thank you!

From the picture, this could be a benign tumor like a wart, but without seeing Marco in person, I can't say for certain. 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 its 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 if needed. Give his vet a call today to make him an appointment. Best of luck.
