I have a couple mares that I thought were bred and due in July. They progressed as normal and then poof.... nothing, size went down and I am assuming false pregnancies. The one mare done the exact same thing 4 years ago. Anyway, I guess this second mare going to do the same. ( no relation ) Anyway, neither mare is coming into heat or showing any signs of cycling. They wouldn't have a later due date as no stallion with them after they were caught last year. Any thoughts. Have a call in to vet but won't hear anything from there till possibly late afternoon or tomorrow. Any thoughts out there, or similar happenings.
