My boy had a TPLO back in November. It took him a while before he was using the leg normally and putting his full weight on it. By the time we went back for x-rays 8 weeks out, he was still favoring it. By 12 weeks, you would have no idea he even had surgery other than his patchy looking leg hair. Now in May, almost 6 months later, he’s back to full activity and doesn’t miss a step.
