I believe I would get a second vet opinion using those films already taken plus the consulting vet may want to take a new view for comparison, plus a view of the other leg for comparison, just in case that vet missed something and to be sure there is nothing really there. Doctors and vets miss things - they do. Since the only way dogs can usually "talk" to us when something is wrong is by behavior, any significant change in behavior or off behavior should be checked out when it is different enough or repetitive, etc. If there is something going on with his back, hip or leg, catching it early could prevent a lot of pain and suffering. And for a dog to start holding up one leg outside is just odd and not typical.
