When I took Punk to the vet in June, I had her x-rayed because I noticed a little hitch in her getalong. The vet showed me the xray of Punk's hip dysplasia - he said that fortunately Punk is so heavily muscled that the muscle is keeping her hips together. I have her on Movoflex right now and it seems to be helping. I have also noticed just this past 2 weeks that in the evening Punk is starting to shiver, like she is cold. I keep the house at 78, so I'm not sure if it is the temp - she is 8 and half years old. When she shivers she has this look on her face that says - help me mom. I go to her and hug her and cover her and after a while it stops. It was only every couple of days, but now it is almost every day, sometimes twice on each weekend day. Does anyone else's old bully shiver? I was wondering if is like when us humans get older and we like the temp to be warmer.
