Our 5 yr old male cocker spaniel is in his 2nd week recovery from TPLO surgery. They say no running or jumping now. We've been super careful but one time when he was taken out, he saw other dogs playing past our backyard and darted so hard and ran to bark, that he got away from one of us even though he was leashed. So what's the concern here? What could running cause after this syrgery?
