I’ve seen that in a couple of dogs and it has always stayed drawn up. Saying that though, they all were three legged hog finding machines. Didn’t really slow em down much. Long races was a struggle, but you can pick him up, but if he’s got the heart and drive, I’d keep letting him find a few for me!
Agree especially if it was a back leg bc they use it like a pogo stick, front legs not so much b/c they need them for cutting etc. My buddy had a 3 legged dog that died of old age striking hogs
