How would you position a dog with only one leg for xrays?

I am an x-ray tech and my dog is an 11 year old pit/hound which is missing her back left leg since age 1. She fell from a walking position and has not been able to walk since for the last 36 hours. I want to take her to the x-ray school I attended and take hip views. My question is, is there any special positioning to concider for her as she only has the one leg. The left leg is amputated flush with the under belly. Any help would b greatly apprieciated.
