I have a 2.5 yr. Old buckskin that developed a sore on her neck last mid summer. She constanly scratches it with her rear hoof and keeps it open. I had her into the vet. And they did some scrapes and nothing was found. The vet gave her Tucoprim powder and had us put Otomax on topicaly. It seemed to have started to get a little better ad now it is back to where it was. We have tried blue coat, red coat, vetrycin, ..... Do not know what next.?.? I have a few pics attached.
Thank you all
