Ripper: The point of breeding her is to get a baby off of her, as she was my first horse and I am very attached to her...so a weanling wouldnt do. Thanks though.
Everyone else: Thanks for all the helpful advice! I know I couldnt barrel race her the whole time. Just the first few months, she is extremely healthy and fit so I don't think that would be an issue. Although, I probably wouldnt even barrel race her just mainly trails and some walk trot lessons with the kids. I'd be super protective of her.
Ofcouse, I am not going to do anything without my vet's opinion first! Thanks for the help! Any more advice would also be helpful!!
