I have a 10 year old basset hound. He recently had a bump on his back and it opened up and was a hole that went down into a cone shape.We cleaned it and bandaged it but the bandages kept comming off. it started to close. but now it has turned into a big growth. It bleeds and sometimes oozes puss. what could it be
