I don't care what anyone says, losing a pet is one of the hardest things ever. We lost both our dogs last year. Our vet gave us 'Dog Heaven' to read to our 6 year old. It's so sweet and it seemed to help my daughter with the losses. She talks all the time about how our dogs are in Dog Heaven and are very happy. Maybe you could do some sort of memorial when you are there. My daughter made a stake to put in the ground in memory.
So sorry you have to go through this! :(
