I too had a dog that did the same thing and at the time was so worried that there was hip problems. At times he even "bunny hopped" alot where he just bounced around. I seemed that when he got older he started to do it less but so I began to wonder if it was just growing spurts. I sent in his OFA x-rays when he was two and they rated an Excellent, so I guess some dogs just do this and it has nothing really to do with the actual hip structure. Actually I didnt know what to call it but now that it has been explained in this thread I see and understand why. Thanks, even though it was not my question, I have had a question answered anyhow.
