The hoof will tell you if it needs a scoop done. If the coronary band has a bulge or is not a straight line (very hard to see on hairy legs!). Also a scoop can be useful to relieve flaring in the quarters.
|Very slight quarter scoop.|
|Scoop to help relieve quarter flare and the coronary band. (Beckham, 2006ish? One of my very old trims)|
|This horse had foundered. Not the bruising in the toe. Noticeable scooping. (not one of mine, just a googled image)|
Apparently quarter scoops are a little controversial in the online barefoot world (what isn't!!) but I have always scooped the quarters if the hoof tells me it needs it.
