I am just reading this for the first time and Stu I feel so bad for you..I can feel the pain and worry in your posts as to whether this surgery did more harm than good..unfortunately sometimes that is the case..but also it does sometimes take time to heal...and remember he is a senior and will probably take more time to heal than a young pup would...hopefully he will start regaining his strength..he has an amazing family in your and your wife!!
