I am a first time breeder and used a well recommended insemination specialist vet. A couple weeks ago my mare (I will post pics below) was inseminated--now I am currently waiting to test her.

Here is my mare, she is half friesian/half AQHA Paint. Her sire was Nanne (17+hands and is now passed away), and her AQHA bloodlines go back to Doc Bar:
