Aside from the obvious looking at conformation, study your horse's pedigree and the pedigree of potential stallions. Learn everything including traits, look at certain crosses and their offspring. Make contact with responsible breeders and ask questions, read. A horse may have a great pedigree with great conformation but until she foals or "his" foals are on the ground is the only true way to tell. Educating yourself to the fullest will greatly help you make a good decision when the time comes to breed. When you decide to breed, talk to your vet about proper care etc. and again, read....I think it is great you want to wait to breed, it will take a lot of time and research before one can make an responsible decision on breeding.
