I was told my serval on here my horse is "skinny" but she does run allot an it a pretty decent sized horse.. Does she look "skinny" to anyone?..The horse i'm talking about is the chestnut colored one..
I agree, the sorrel is thin. Ideally, you shouldn't be able to see the ribs at all. She doesn't yet look like she's starving, but she definitely needs either more food or something higher in fat than what she's getting.
