Basset with elbow dysplasia surgery

Hello folks - first post on this forum and thank you in advance for the assistance. My 2 year old basset (Zack) had elbow dysphasia surgery on Wednesday 8/29. No pins on the outside but the ortho used wires instead. For the most part he is doing OK - lot of pain controlled through meds but one thing is that he is refusing to put any weight on the leg. The on-call this weekend was not much help so looking for some insights from folks who have gone through similar surgeries. Many thanks.
