thank you everyone,, you are all awesome. yes Barney had it very young, just under one year.. but his knee was slipping constantly and I just could not bear it any longer.. surgery was inevitable and since he is pretty much full grown, Dr said it was fine.

His spirits are good today.. he is always smiling and wagging his tail. I took him on his leash today and walked him around my house. He basically scurries around and then sits after a few minutes... since today has been four weeks since surgery, I just have to give it some time and realize he is going to limp for awhile.. I am a worry wort for the most part

Thanks again for all your support
