I live in Minnesota and have downsized by horse family from 3 to 1 when I moved. I am now considering purchasing another horse. The horse I am currently looking at is in Iowa. I have never purchased a horse out of state, and I am curious as to what all I need to have done during the pre-purchase vet exam, as well as what you would suggest to have the vet do/check for. I am aware I need to have the mare I am looking at tested for negative coggins. What else would be required to have done at the vet in order to cross state borders (if I choose to buy her and bring her home to MN)? I have also heard to find my own vet in the area that the horse is from, instead of going through the owners usual vet.
