Okay, a couple of days ago I posted about my calf who has an injured leg. It is really on his hoof and there are white pus coming out. I called the vet today and got some advice and instructions on what to do. I need to give this calf antibiotics or penicillin. He said there is short acting and long acting penicillin but what is the difference? I forgot to ask my vet that question.
