I have an 11 year old mare who according to the research I've done and the vet has mud fever/scratches. It's been an on and off thing since August. She's never before had anything remotely like this until recently. Back in August, the scabbing was primarily on the lower half of her left hind leg. The vet removed as much of the scabbing as possible, said to clean the area daily and apply an ointment twice daily, and prescribed an oral antibiotic. The scabbing subsided but never completely disappeared and now the scabbing is appearing on the same leg but seems to have spread and that leg is noticibly swollen. Again, the vet prescribed more oral antibiotics and said to cleanse the area with an antibacterial scrub. We're already gone through half of the prescription and her condition doesn't appear to improving, though I can't say it's worsening either. I'm really at a loss at what to do, and our vet can't seem to offer any other suggestions. From the research I've done, some seem to suggest soaking the scabs in order to remove them, then apply ointment daily, while others say just to apply the ointment directly on the scabs until the area is healed. And of course there are a wide range of ointments people suggest. Also, it's been very wet and rainy here and as a result, her pen is muddy and the pasture wet but not muddy. The vet never suggested taking her off the pasture and as a result, we have never done so. Does anyone have suggestions as to how to treat, what to treat with, and issue of keeping her confined to her stall during treatment or if releasing her in the pasture is ok? Thanks guys.
