Very good idea to check the joints first before weight pulling. $100 for xrays LOL That is very cheap, don't want to say what i've paid in the past for xrays :( In general, "if it ain't broke, don't fix it". Dog is moving fine, I wouldn't worry about it. Just like sports injuries with humans, dogs get them too, except they're a lot tougher than we are. An ocassional wee limp for up to a week is to be expected when working them out heavily. As soon as the limp is gone, start them up again slowly. The supplements won't hurt, but no reason to have him on anti-inflammatory meds. The only place i've ever heard of drawer test, is here on this forum, so can't comment on the case of sedative for that.
