Yep, second guessing, though natural, is a waste of energy. I didn't really second guess because I knew that no matter how much time the amp bought Winnie, that pain of osteo and the risk of that leg suddenly shattering, was gone. I wish that I could say that there weren't times that I looked at my beautiful girl and wished that she was whole again, but that wouldn't be true. My heart ached for her when she plodded up and down our steps like a trooper, or when she wiped out on a slick floor, but I knew that I'd done the right thing. There is no stigma in the dog world against 3 legged hounds, and that spirit that captured you forever is still intact, a missing appendage is superficial in the larger scheme of things.
Be sure and keep us up to date with his progress. Lots of prayers and white light.
