I would have done the same as you, waited and rested the dog. Then, if it showed up again, gone to the vet.
So you left your pup with a dislocated shoulder for over a week, and even hunted her with it before seeing a vet. Bravo! I hope, for your dog's sake, no lasting damage happened.
Nobody gets macho points for letting his dog suffer. Waiting a few days in hopes that a problem will go away by itself is (sorry, I can't think of a polite way to say this) stupid. If the dog is injured, you're leaving it in pain and the problem may get worse. If the dog is okay, whatever you pay the vet buys you peace of mind - and fulfills your responsibility to your best hunting partner.
Our dogs trust us to look out for their health and safety. Please, don't let 'em down.
