Amy I agree w/Carol… it doesn't make any sense that after 4 surgeries they are NOW calling for amputation. I would get a second opinion, but if that's NOT an option for you (financially or emotionally) then know that Radar will do FINE w/just 3 legs. A very good friend of mine had a 3 legged lab named Charlie and he was my Roxie Girls boyfriend. He was the HAPPIEST dog ever… and he could outrun ALL the dogs!!!
Please do not for one second feel guilt over this… you have done everything in your power to help your boy. Sometimes no matter what we do things do not work out the way that we planned, and it's okay… you know we will be here for you no matter what decisions are made.
