I know the feeling , about 2 years ago i had to take Face my Rott in for the same reason, and it broke my heart to leave him while he went under to be x rayed.

Im sure everything will be alright, even if he does have Hip Dysplasia, i found out Face did, but he is 6 and going strong, once in a while he will take a pain killer if i can see it is bothering him.

We will be praying for Keegan, let us know the result.
