Don't worry about it. Lots of judges will reward cow hocked dogs. We see it all the time.

Then that means it is the right thing to do? Advise someone to show a dog with bad structure just because judges reward it even though it is not correct. We need to keep the breed sound and not just show dogs with faults because other people do it or because some cow hocked dogs win with a professional handler. Two wrongs don't make it right.

Just because a dog might have a sloppy stand does not mean they are cow hocked! Watch the dog moving away, then if the hocks turn in, OK. Just as an additional note I have never seen a cow hocked dog rewarded.
Sometimes I sit with one leg under me, that does not mean I only have one leg!
