Dear Dr. Mike, I live in Tallahassee, FL and my daughter's 17 yr old welsh pony has a strange problem with the skin directly above his cornet (sp) band. Even my own vet and my farrier have no idea what it is or how to treat it. As a result, I have tried so many different remedies and nothing seems to totally eradicate it. He is not at all lame. He is out 24/7 but has access to a large run in shelter. He grazes on lush pasture which we fertilize twice a yr. None of my other 2 horses are affected by it. I have a funny feeling the wet summers exacerbate the problem and standing in moist grass. I think if I could put him in a stall and keep his feet dry this would help, but I cannot at this time. We do plan to build a barn later this year. It is so bad his heels actually bleed. I have tried triple antibiotic ointment, fungicides, and betadine washes. I even took him to the Gulf of Mexico and let him trot through the surf and this did seem to help for a week but it came right back. Do you have any suggestions? Sincerely, Debbie Clark, submitted via HorseGazette.com (2 pictures attached) Dear Debbie, This sounds interesting to me. I am assuming that this has been going on for at least several months or even years. You don't say whether the horse has been on any systemic antibiotics. The fact that the salt water made it better leads me to believe that it might also have an infectious component to it. Bacteria doesn't normally live well in salt water. The wet grass could be the initiating factor and then you might be getting a secondary bacterial or fungal infection. I talk often of the merits of biopsies and I think this is a case where a biopsy of the affected area is certainly warranted. I think the results will give you an idea about which direction to proceed in. I would also try to get the horse to a drier environment. – Dr. Mike Dear Dr. Mike, I have a 4-week-old foal that is losing hair around the face and where her tail rubs on her rump as well as some of her legs. Is it some sort of mite or bug that would cause this? She was fine the first 3 weeks. – John Lewis, submitted via HorseGazette.com Dear John, The hair loss could be caused by a number of reasons. The ones you mentioned are all possibilities. Has the foal been de-wormed? Is the foal itchy or scratching itself? Are there any raw spots or just hair loss? Are any other horses affected? Is the mare experiencing any problems? All these questions need to be answered. Are flies or mosquitoes a problem in your area? A physical exam by your vet would be a good place to start. Your vet might also do a skin scraping or skin biopsy. Fungal skin infections, mites, and fly bite hypersensitivity could all be factors in the hair loss. Have your vet take a look and see if you don't get some answers. – Dr. Mike Dear Dr. Mike, I just purchased a 17-year-old Oldenburg mare 2-3 months ago. Her old owner had not ridden her for approximately two years, but she has been trained up to third level in dressage. I started to ride her a week after she was moved to my cousin's barn. 1 month ago the vet diagnosed her with cellulitis in her left hind leg. She was put on penicillin and given banamine. The vet thinks that bacteria had gotten in through fungus that was on her heel. Could stress from moving to a barn of thirty horses from a barn where she was the only horse and new bacteria have also caused it? She has recovered and I am starting to ride her again. Her old owner told us recently that she has had this before. Will it be easy for her to get it again and how can I prevent it? – Deb. S., submitted via HorseGazette.com Dear Deb, There are several things that can cause cellulitis. Infections, auto-immune disorders and Strangles can all be implicated in a horse with cellulitis. It is also possible that the horse kicked something and caused the limb to swell. If the horse responded well to the treatment you described that I would say that is good. There is always the possibility that it could happen again. If your vet feels that it was caused by a bacteria or fungus from a wound then I would do my best to stay on top of any abrasions or wounds. Keep the bedding clean and keep an eye out for any signs of infection. – Dr. Mike Dear Dr. Mike, A pre purchase vet exam flex test on front left showed lameness. The farrier says there is nothing in the feet. Will x-rays show what is causing lameness or maybe not? I am waiting to purchase this 4-year-old if she is sound in another flex test and x-ray in two weeks. She is sound to ride but she flutters her knees like she is off balance. The vet and farrier say she is balanced. What could cause this bobble/buckling/trembling in the knees when she moves out? She trots and canters fine...thanks, Sally. Submitted via HorseGazette.com Dear Sally, I am not sure I understand what you mean by fluttering? I do know that if the horse is lame I would be cautious about buying it. On most pre-purchases an exam is all we get to do. There is very little diagnostics that can be done at that time. If there is some lameness issues than a complete lameness exam with diagnostic nerve blocks would need to be done. Unfortunately most sellers don't want to get involved in that. Some horses have congenital problems such as contracted tendons that can cause limbs to shake or "flutter." I think you are doing the right thing by looking at the horse at a later date. I always recommend x-rays but I don't know whether that will answer all your questions. Bottom line is don't buy a lame horse. – Dr. Mike
