I had the vet out a month ago to preg check my mare and she said no, I'm wondering if its possible for them to be wrong sometimes? My landlady said that they had a horse once who the vet kept saying no and that she wouldn't catch because she was so overweight. So everyone pitched in and took turns riding her out to try and thin her down and then one day we put her in the stall and the next morning she popped a baby out. So yeah, my mare was in with a stud for 2 months right after she had her baby that passed away a few days after he was born. She's always looked pregnant as she had 3 babies in 3 years but she was starting to slim down because I was riding her every other day and no her belly is starting to look more pronounced.
So can vets be wrong?
