Filly Mounting Other Equines?
Disclaimer: not my horse. Will likely be headed for a vet work up asap.
This is a rather strange case. I've known this filly since she was 3 months. She's now 3 years old. Sensitive temperament. This spring she came REALLY into heat and hasn't been out of heat consistently since. She will do nearly anything to get to the stallion, even though she is pastured away from him. It was unusual, but she's young and the weather has been strange, so they let it slide. But it's not getting better. In the last week she's been seen mounting other horses. Today is was a gelded male mule. Other than being a stereo typical mare in heat around other horses she seems fine.
I recommended she get a full check asap. I've seen mares that act like stallions before, due to hormone imbalances, but not quite like this.
Anyone seen anything like this?
