Horse Veterinary Questions? Ask an Equine Vet.
Good Morning and welcome! I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
THis condition often will be self limiting and resolve on its own. It appears that your mare probably has a suppressed immune system due to heredity and often this will also require systemic antibiotics due to secondary staph infections. Pencillin is not a good medication for this but Trimethoprim Sulfa or Cephalexin will work better for this since Penicillin has a very narrow spectrum. FRom your description, you are doing all the right things and I agree that your mare probably will require systemic antibiotics to totally rid your mare of this condition.
Check with your vet about these medications since they are only by prescription.Does that make sense to you?
Please let me know if you have ANY other questions. My goal is to give you 100% satisfaction and if you are not yet satisfied, please REPLY so I can clarify for you.Sincerely, ***** *****
