Oh Amy I'm so sorry to hear this. It's inevitable that we lose our pets before we are ready for them to go. He had a wonderful life with you all and was a very lucky dog to have such a family. I'm sorry for you and for your mom and family, I know this was so hard for you to do. It was best for him, even if that doesn't seem like any comfort at the moment, you gusy did the right thing. He will always be in your hearts and he is happy and whole again, with no aches and pains. You will see him again.
