As much as people say that horses 'even up' when they are butt high when they are young.. I think 'not so much.' I expect he will be a bit down hill and muttony withered as an adult.
Don't agree, sorry. Not that this applies to every breed, but I know a lot of young WB's that have got two very uphill built parents, and were incredibly downhill from between 3 months old up until almost 3 year olds. One didn't come right up in front until 5, and now he is beautifully uphill. My colt (now gelding) is almost an inch higher behind than in front as a yearling, though his sire is known for throwing brilliant front ends and his dam was one of the highest scoring hannoverian classified TB mares on the recent German studbook classification tour in Australia. I am certain that he will even up ;)
As for the pony, he is lovely! Conformation is not foot perfect, but as a good, solid all rounder he will be great. Backs a little long, shoulder's not brilliant etc but most do get pretty ugly as yearlings. I won't tell anyone how much I paid for mine at the moment when they see him (double figures
), he looks like some backyard mutt from out in the sticks, donkey x something that fell over the back fence!!!
It's hard to tell exactly what you're going to end up with from looking at a yearling. Your best bet is to look at that at 3 days, 3 months and then don't look at them again until they're 3 years when they START to look more like a real horse again!! Have a look at both sire and dam, and any progeny produced from either parent, to give you an idea of what he'll mature like.
