my poor summer who is nearly 4 had a large abscess under the jaw, they drained it about 2 weeks and i have been milking it, and she was on antibotics and i was cleaning it - but the hole closed up and the puss was still there as you should smell and its smells bad, so i took her back to the vets today and they have reopened the hole and a bit of puss came out, she is now on septrin and flagyl-s susp to try and clear this bateria - has anyone had the same problem and will this new medicine finally get rid of this puss from the abscess? - i feel really sorry for her, as he's getting old - i will be cleaning it and draining it, but i am hoping this abscess does go. She is eating fine. The vets she went to are pretty good with guinea pigs, so i am hoping this will now work?
