The first summer that Betsy was here, she started limping on her right front. The x-rays showed tendinitis in both shoulders, with the left actually being worse. Rest and Metacam helped.
But then she started limping again in the fall. In January, it was awful. We restricted her activity and tried Metacam. No improvement. Then we tried prednisone. No improvement. Then a couple of months of therapy (underwater treadmill). Some improvement. By April, she was doing really well.
Then, as soon as it got cold again, she was limping.
So it took more than a year for me to figure it out, but she is lame when it's cold. She tends not to limp inside, but my house is small so it would be hard to notice in any event.
I hope Polli is just reacting to the temperature.
