Tina - loosing a dog is loosing a child or an immediate member of the family. It's something you never get over, but the pain does ease. You will always want Snoop to be a part of you and never forget him.

You will intime remember the good times and the bad will fade.
I have lost 3 dogs in my time , all were very old, happy and healthy, i still cry every day, still hurts years on. For me loosing a dog is the worst thing ever.
I know how you feel and send you love and hugs.

You did the right thing as you didn't want him to suffer. Some people can be selfish and keep there dog alive evern when suffering.
