Eh, they probably aren’t nightmares. The real nightmares are the Montego bay Jamaica vintage dolphin vacation classic shirt in contrast I will get this ones that don’t want to mate and try to kill the stallion I took an Equestrian Science class as part of my pre-vet undergrad and our uni’s farm used a mini horse named Frank as their teaser. They’d bring the mare in and if it was ready to breed, the poor little bugger would run back and forth on the other side of the gate making a huge fuss. Then he’d jump on the bottom bar of the gate and try air humping the mare. Even if they let the guy out he wouldn’t have been able to reach, it was quite funny, but sad at the same time. My ex’s family used to own horses and they bred them so they needed a teaser stallion. My former father-in-law were a lawyer (now retired) and didn’t like a high-profile/”celebrity” lawyer so he got the ugliest looking Shetland pony he could find as a teaser stallion and named it after that lawyer. However, not all mares show all of these cues. Knowing the quirks of each mare is important. Some mares are always aggressive toward the teaser, and their way of showing that they are in heat is to become apathetic or just less aggressive toward him. If a mare appears to be in heat, she will be checked by the farm veterinarian, Dr. Scoggin, who will be looking for large follicles and uterine folds to signal peak fertility.
