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.
