Thanks again everyone. I'm feeling better about it. I know he's in a better place.
Ten years ago my old hunting dog had to be put down. The vet did the job and then we had her cremated (dog, not vet ;)). Later that day I was standing in the kitchen when suddenly it was filled with the smell of wet dog and I felt a beautiful joy. To do this day I'm convinced Tina (my dog) came back from where ever she had gone to let me know she was happy and I did the right thing.
Animals may not go to heaven, but they go somewhere and it's a good place.
