We were told he was a Qtr horse, which is what most people have around here so when in doubt they always say "oh, he's just a Quarter Horse" lol.
He has white that extends down under his chin and he has an odd stocking. I haven't really checked for any belly white but the whites of his eyes usually show.
Based on his teeth and what others have said here he's around 4. All we know about his history he was left in a huge pasture with other mares and stallions and he was going to be shot so a lady got him, another stud, and a couple mares with foals and found them all homes except for Sundance so we got him as a free horse.
When we got him he was ribby, had several bite marks, had a minor wound on his right leg and didn't like people much, he was just very standoffish and unsure.
When he lopes it looks very smooth and he also has a nice trot, but he sometimes does a little odd gait, not sure what it is. He does it when he's in a fast trot.
He doesn't ever stand square, he seems to always stand in a semi-parked position lol.
He has an overstride also
You can see how that one stocking just narrows up his leg
One from a couple weeks ago:
I'm guessing he's a Paint cross, just not sure what the cross is.
