Aires is only two, so he has quite a bit of growing left to do, but as of right now he stands right around 15.2hh. He is a spotted draft/Percheron cross. His sire is built like a tank, but stands 16.3hh (if you scroll down, his sire is Pete, the spotted draft stud that is the sixth stallion down Edelweiss Percherons - Stallions ). His dam was pure Percheron. Aires is built more like the Percheron than he is like his sire (more lean). So, my concern is, because of his breed(s), I know that his shoulders are more than likely going to fill out quite a bit. Right now he's built like a well-muscled QH, so a regular Aussie saddle (with the stuffed panels) will fit him fine. However, when he reaches his "big boy" size, that will more than likely alter the fit considerably, right? I know it's difficult to predict, but I'm hoping other draft horse owners can help me with this. Do you think I'll have to get a whole new saddle specifically made for draft horses, or should whatever Aussie saddle I purchase now still fit him in three years? Any help anyone could give me on this would be GREATLY appreciated. Later down the road (we're talking at least a few years because of how expensive they are), I definitely want to have an Australian Stock Saddle Company saddle specifically fitted to Aires, but for now, I'm going to have to go with used.
