Q. We have a Quarter Horse stallion that we will be starting in a shipped semen program this year. All of us—the stallion, our veterinarian, and our farm personnel—are new at collecting semen. We are in the planning stages for our breeding room and trying to make decisions on a dummy mount. Our vet said that you gave a talk on dummy mounts at the American Association of Equine Practitioners meeting and would be able to advise us on dimensions for our dummy mount. We have only this one stallion, at least for the first year. He is 15.2, with a very long body for a Quarter Horse, and he is very athletic. We would appreciate any recommendations on how big we should make the dummy for this stallion.
