I don’t think anyone can give you a true stallion suggestion as nothing has been said about the mare other than breed and height. Only stallions that produce color or have been bred to a draft in the past have been mentioned. What needs to be determined (and you can describe this without necessarily having pics for everyone) is:
how is her head, neck set?
How is her saddle position?
Her legs? Her croup? Her topline?
Her gaits? walk, trot, canter? Jump?
Has she been bred before? What about her parents, do you know her lineage?
These are the most important questions regarding the mare to help you determine a stallion choice. Then once you get that settled start looking at stallions. Ask what traits the stallion passes? How are is offspring doing in sport? What are the terms of the breeding contract? You need to look at conformation shots of the stallions, video…not just a single picture on the internet.
You best chances of breeding what you want will be greatly improved by doing lots and lot of leg work before hand. Sadly, it is true though that you have a much greater chance putting that leg work into buying a horse already here. This way you can determine that is has the conformation, movement, temperament…and color that you desire. It has taken me 8 years to finally get the filly I have been trying to breed…and that is after 3K in breeding fees (stud fee, vet fees) , 15K for colic surgery the mare had 24 hours after foaling and the approximate 3K it will cost to surgically correct a defect the filly has. That is a lot of money that was not “prepared” for but had to be done. I could have traveled all over the place looking at horses for that much money!
I don’t breed a ton of horses by any stretch of the imagination…but in my small career I have had one foal die from trauma, one red bag delivery, one post foaling colic, one year of 5K in breeding/vet fees and no pregnancy, a foal with physitis, and now this year with a mare colic surgery and a future surgery on the foal. And I am vet that does EVERY preventable measure possible for safe breeding, foaling and raising of youngsters!!! It can be MUCH cheaper to do a lot of internet searching and a little travel and buy a horse already fitting your desires.
Remember, when breeding your own you are “buying sight unseen”, have to get the mare pregnant, safely through 340 days of pregnancy, then through 6 months of foal time, then weaning and three more years of the most trauma riddled years until you can even ride them!
