Abnormal Elbow(?)

Hello! Can someone take a look at these pictures of my almost 5-month-old basset hound puppy’s leg? It almost looks like his elbow or shoulder turns away from his body. I know puppies are flexible but it seems a little excessive to me. Am I worried for no reason? It is a little more exaggerated at times than at others. It seems that it does this mostly when he is turning in the direction of that leg. I have touched it and felt around and he seems to be in no pain with no limping either. We have a vet appointment scheduled in a little over a week. Just looking for some information!
