Beyond a year:

Cosmo is doing wonderful. He walks, runs and plays. He does not need his brace. He is back to his old self. We do monitor his activities closer now but feel that he is healed. I would say he regained 95% use of his leg. The only reason I do not say 100% is because some days he is a bit stiff in the morning. This could be arthritis.

I highly recommend Conservative Management!

Cosmo is doing great. I hesitate to yell it from the rooftop, but Cosmo is walking just fine. He is playful and happy. The only sign of injury is the occasional popping noise. Granted, My knees pop every morning when I get up so I am not worried about the noise.
I am VERY thankful that we went the conservative management route. Despite being a large dog, it did work. Cosmo was spared the surgery and that is always a good thing.

Cosmo is walking completely normally now, without the use of the brace.
There is still an occasional popping noise but it reminds me of my own knees cracking when I get up off the ground. He runs and plays and acts as he did prior to his injury.
I am thankful for all the help and advice I received along the way. I am VERY thankful that we did not put him through surgery.

I am hesitant to post this (as I would hate to jinx us) but Cosmo is doing GREAT!!! A few days ago, he ran and ran. He ran without pain. He ran with excitement. He was the playful & joyful dog that he was before his injury.
Is he 100%? Not quite but he is almost there. He is at the point where when he decided to run we did not stop him. He is not wearing the brace. He is very stable without it.

It has been a month of no problems. Cosmo uses his brace when he goes outside and we take it off when he is inside. He loves wearing the brace because he knows it means freedom (going outside to play).
He still swims daily and we still give him the same suppliments.
I am very pleased with his progress and our decision NOT to go ahead with surgery!

Cosmo is continuing to improve. The brace has become part of his daily routine. He is swimming a lot and has lost some weight.

By the time we video taped Cosmo, he resumed walking normally.
He is back to using his brace most of the day. He is walking on all 4 legs with the brace.
I am going to try to include the video.
