I am so sorry to hear about Rocky. Based on your photo I suspect he has what we call a "hot spot" or acute moist pyoderma. This is a bacterial infection of the skin and can be painful and itchy. Most often we treat these by shaving and cleaning the area then prescribing a course of antibiotics and steroids. You can read more about this at http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=2714. I would recommend setting up an appointment at your vet to get him taken care of!!! Hopefully with treatment Rocky will be back to normal soon!
