Hi, welcome to the forum! Haha, I'd just like to warn you that the "to geld or not to geld" question gets a lot of people riled up on here; so be prepared... And remember, everyone on here is very nice, there are just some very strongly-held beliefs!
I think Durmax is quite young and fuzzy for a good critique- in three more months he's going to look like a different horse, for that is the life of a growing youngster, haha! But I'll try to give some sort of critique.
He definitely looks like a baby! He seems to be pretty sickle-hocked, and his front pasterns look a bit long. His shoulder is straight and his back seems a bit long to me. He has pretty good length canons and his bone looks decent, but I think overall he's best off as a gelding. He's cute as a button, and he looks sweet, but he doesn't scream 'stallion prospect.' I'm sure he'll mature to be a nice horse, but that's not quite enough to make a stallion...
Do you have any plans for what discipline he'll be going into? Feel free to post some more pictures and keep us updated on his progress, he really is quite the cute little guy!!
