Wait your friend actually prefers dubs? Like for real? That's wild to me but I guess I never thought about missing stuff in fights.

Right, because who needs working fire extinguishers anyway.

Right, but is a low heel really that crazy of a find? Most horses have some weird imbalance if you stare at them long enough. I've seen plenty of cracks that just had to grow out regardless of what you did to the foot. Sounds like you got lucky with the trim. Sometimes people overthink these things and start sawing on hooves for no real reason when the crack just needed time.

That's proper scary mate. Cutting loose is the only smart move there.

Put some thin foam weatherstripping between the pegboard and the wall before you screw it in. It lets air flow behind and stops moisture from warping the board over time.
