Thank you so much for your reply! Do some dogs who have been restricted with movement get to the point that they “recover” or is this always a progressive situation? We don’t know if, after the 4 weeks of restricting him, if he will can to return to walks or anything if he is showing that he improved enough. Do you have thoughts on this? Also, is there anything we can do for him at home (like light massage or heat on the back)? Thank you so very much! You are so very helpful! 🙂 -Catherine
