I am a vet so a week after your mare is bred I can do a pregnancy test for you. Just post it in my Service forum on my website. www.freewebs.com/nice-eazy-me/vetservice.htm
Also as a vet I would like to be called for breeding so I can insure that the horses remain safe and unharmed.When are mare foals let me know so I can asstit if needed and dertermin genders.
