Please have your friend be careful in her choice of trainer. When talking about TWH and training there are soooo many different "methods" of training. Talk with the trainer first, before they even touch this horse. Ask to watch a training session of someone elses horse. Ask if a drop in visit is okay before a contract is signed.
I know drop ins aren't welcome at a lot of trainers, and I get the logistics of it. But I'd want to at least ask.
My personal opinion, so many lovely Walkers are ruined, broken, and crippled by certain types of training methods that I would be extra cautious in the choosing of a trainer. Please tell your friend there is a whole internet out there, do her research on methods, and results, of her trainers chosen training methods.
*Goes to look in on her pasture puff TWH* I love my boy :)
p.s. Shoes are very different for showing versus trails. Shoe the horse for the job he is doing, not his past life.
