I just started a new job walking dogs, i thought it would be great because Titan could go with me and we would all get our walks in. But he played to hard on monday. I was walking 4 dogs and heard a loud yelp...saw no limping so we continued on. then yesterday, 5 people told me he was walking funny...when he runs, he does a bunny hop...i don't know whether it is because he was in full sprint or what... so now titan is going to the vet tommorow... being sadated... (yuck) and xrays of hips and elbows are beiing dong... (preliminaries) i hope everything is ok!!!!
