I'm pretty sure I know what to think about this -that it's nothing to worry about- but I wanted to check with the experts.
I trimmed Lacey's hooves again on Friday, as is my usual routine, and spent some time on her back hooves (usually I do her fronts a bit every week and touch up her backs every 2-3 weeks) this time.
Anyway, while I was rasping her backs, I discovered that both of them had some bruising and one had pink/redness nearly all the way around the hoof (white hooves so it was easy to see)!
In one spot, it almost looked like I had hit blood, it was that red. I hadn't hit 'blood' at all but I had a moment of panic!
I should have gotten a picture but it slipped my mind at the time.
If this hoof that I'm trimming off now is hoof from 8 or so months ago, that would line right up with when I got a new farrier last spring who let Miss L's hooves get alllll out of sync. Her back hooves took the brunt of the out of sync-ness (she was starting to constantly interfere with herself in a side to side manner) so I'm not really surprised that there is extensive bruising...
I just want to make sure that it's "normal"!
