I have a 2 month old boer kids that we have been watching a bump on the inside of hie right front leg. It's just above the dew claw on the inside. I have been watching it for about the last week. He would limp on it occasionally but no heat, but is very sensitive to touch. Well today when I felt it it was getting a very soft spot in one area. It is about the size of a large cherry tomato. I decided to stick a large needle in it to see if it would drain and relieve some pressure. As soon as the needle touched it the puss started coming out. I can't believe how much was in there. It is still very painful to the touch. So the question now is what do I do with it.Due to the large amount of puss I was wondering if an antibiotic should be used. I did not see anything when I shaved it that would say something had been poked in there such as a sliver. I know something should be done as I did not get all the puss out and it was still large. Thanks for the help.
