Out of 3 mares, I have 2 mares for sure bred, one at about 60 days and the other around 35 daysThe 3rd mare I figure should be around 37 days or 12, she came into a short heat after being bred the first cycle. He could not see anything on her, but said if she took on the 2nd heat, we would not be able to see it quite yet. First time I got to see an ultrasound be done and it was neat. My vets here do not normally tend to miniatures, and the one mare that I am unsure if she is in foal and due anytime (if she is in foal), he tried to palpate her and he said she was too small for him to go any further to feel. So he did a blood test and we should have that by the beginning of next week. When is the best time for them to see in the early stages of pregnancy? I am planning on having him come back to do the other mare that may be around 12 days along?
