My three year old colt has had some scarring on his left hind like he had a fence injury up on the cornet but didn't ever seem to bother him and I never thought much of it even when picking his feet and getting him ready for his first set of shoes(he hasn't had feet handled that much).
Anyhow right before he was to be shod we had to go to CA for a couple of weeks due to a family emergency and he got turned back out. Wednesday I go to bring him back in and the outside rear quarter of his hoof wall had separated and come off. See pictures below, sorry about the quality.
Just wanted some different opinions on growing it back out and future care if he were your horse.
