My 12 year old Gelding Quarter horse "Rebel" has an abcess on the inside of his right leg but higher up, closer towards his... you know what... Anways, I've tried cleaning it and stuff and it'll go away and I'll think it's gone, then POOF it's back.. I tried letting his own body fight it off, and it goes away, then it's back. I talked to my farrier and he said a shot of Pencillin would help, as an antibiotic to help me fight it off. Would that help? I just wanted to ask, if you don't think it would help I'm going to have a vet come out here this week. Money has been kinda tight, but I can just afford it now. I'd like to avoid it if possible, I sure she's just going to give me some antibotics and tell me to keep cleaning it out. So if I can get some antibiotics from the feed shop then I am pretty sure I could heal it myself. If you know of any other antibiotic I could buy from the store I would appreciate it! I feel so bad for him, like I said it doesn't hurt him I can clean it and spray it and he doesn't flinch but it NEEDS to be taken care of. Please don't chew me out for not taking him to the vet right away, it won't change what has happened. I've been working dillegantly on keeping it clean and antibiotic spray and everything. Thank you.
