I was wondering what breeders here felt was the best time to have an external ultrasound done to see if a mare is pregnant? I've only ever had internals done when I was trying to breed a Morgan mare I use to own. This mare is not the happiest about people touching her lady parts so I felt it was best not to stress her with an internal and wait. I know the time period is very different. I am pretty sure my mini mare is pregnant as she never misses heat cycles. I have the vet coming out this Tuesday (December 6th) to do the ultrasound but want to make sure it isn't too early. On the day the vet comes she would be 80 Days pregnant.
