Re: Putting a dog to sleep.
A very tough thing to do. You have my sympathies, all of you.
I will repeat some advice I've given many times before: after you lose a pet, get a new pet soon.
After one of my cats died, my wife, my other cat, and I were utterly miserable for a couple of weeks. Finally, we decided to get a new kitten. Best decision I ever made. Instead of sinking deeper into depression, we were all enthralled by the new kitten (I named him Griffey). He actually brought back fond memories of the old cat -- we noticed all the similarities and differences in their behavior. We were much happier, and I'm sure my old cat would have wanted it that way.
