My horse is the thoroughbred on the left. (this is the only frontal pic I have on my comp at the moment.) Is it just me or is his face.. well... really skinny? I mean, is this a commmon thoroughbred trait because the horse next door in the pic is a thoroughbred also and he has a realllyyy broad forehead (well, it looks fatter in real life lol)
thoroughbreds can be so different from one to the other, I've had some that were really solid with big broad heads while others have been quite fine, I guess it comes down to there pedigree and to which characteristics are passed down.
Your horses head is much like my mares, so I wouldn't stress
Sorry about the piccy, it's a bit old.
