i'm reallyl sorry david, i have had an animal put to sleep too, i know how you feel, i am a big animal lover. how old is your dog? do you have any pictures? if not take some pictures, spend time with him, give him all the table scraps he wants, and before you get him put to sleep, clip a tuft of his fur off and put it in a bag. that way, you will have something to remeber him by. and you want to make the rest of the week the best week hes ever had, so spend time with him, give him table scraps, and try feeding him spagetti and meatballs. dogs love that stuff. i am wishing you the best. and pm me if you'd like to talk.
