this is sad news. It's easy for people to say if you should put a pet down or not by his condition at the time. But it's one of those things that's easier said than done. Personally I can never do it. I'm one of those that strings on to the very end like some miraculous recovery is just around the corner. But so far that hasn't happened. I hope I don't have to go through it again for at least another 6 years or so.
