Wait, are you telling me you can still find old product labels? @elizabethhunt I swear every time I go into a store now, even the vintage looking stuff is printed fresh with that exact mustard color. It's like they all bought the same sad paint bucket. Nature photos are a good call, but then you just end up with fifty shades of beige from rocks and sand. The whole thing makes my eyes tired. We need a law against using slate gray on one more wall.

What kind of filter did he go with?

My farrier sees that all the time in older horses. It's often just a minor conformation quirk, not a real lameness issue. I'd want a vet's opinion before changing the whole shoeing plan.
