I'm sorry Pogo has this going on. Many things can cause what you describe, but I am suspicious that it might be an infected and now ruptured tumor. This could be benign or malignant, but should be evaluated quickly. Your veterinarian may have to treat the infection before they can diagnose what the lump may be. In the mean time warm compresses may help it drain and make Pogo feel better. Keep him indoors and away from flies or the wound will be full of maggots in a day. Good luck to both of you! I hope he improves quickly.
