The picture you posted does not look like a pimple, so I am worried that it is actually a mass. Anytime a new mass is noticed, I always recommend having it evaluated to see what it is and if anything needs to be done about it. Unfortunately, we often can't tell anything about a mass by just looking at it. Your vet can perform a simple test called a fine needle aspirate where they use a small needle to collect some cells from the mass, then look at them under the microscope. They may even need to send the cells to the lab for a pathologist to examine them, so we know what the mass is. If it is benign, you might not need to do anything about the mass at all, but if they see cells that worry them, they might recommend removing the mass. If the area is infected, then your veterinarian may prescribe oral or injectible antibiotics to resolve it. Good luck! I hope that was helpful.
