my nuetered male dog got to a female dog in heat. for the past 24 hours he has had a full "erection" and appears to be in pain. i have tried lubricating the area as well as applying a wet compress. neither have worked. my vet wants him to be seen but they are not availble until next week. is there anything i can do to get the swelling down? is there an anti inflamitory i can buy over-the-counter?
