About two months ago I noticed that he had a red spot on his inner thigh, it looked like he scratched his leg while peeing on a bush. There was not any broken skin, the area was just red and irritated, about the size of quarter. It stayed red for a few weeks then the redness went away and 5 small flesh colored bumps appeared. A few days ago I noticed that the bumps were filling with puss and now look like pimples. They have been getting progressively worse over the pasted three days. He hates going to the vet, causing both of us great stress, and do not want to have to take him to the vet unless it is something serious. Thanks for your help!
