Okay, so I'm looking at a yearling Welsh D (most likely, he's going to be a borderline height). Anyhow, one of my concerns with him is that he has really large ears. I know it doesn't really make a difference in the horse, but I'm really wanting to buy the closest thing to my "ideal" Welsh, and I really love the small pony ears. So I was just wondering if there is any chance that he might grow into these ears? I don't have a lot of exposure to young horses, and while I don't think ears grow at a different rate than his head, I figured I might as well ask.
Yep, he might grow into them a little but they'll likely always be at about that proportion to his head. My filly has GIANT ears for her breed but I think it just makes her all the cuter. I'd say the same for that colt, and if I remember right he's a very nicely put together little animal. I wouldn't bypass him for his ears at all.
His ears will never be small, like others have said, but he will likely grow into them. If he is a nice colt, which just from this pic it looks like it, than I would not let ear size at all be a factor. If you can, look at his parents and you should be able to tell what he mature to be. If they have mule ears, then you probably won't get lucky. My filly was born with her dam's ears and has a similar face, so I wouldn't think her big ears would get any smaller.
