One of the hardest decisions we've had to make was when a vet told us to take our dog home and give him the best 24 hours possible because he was old and suffering.
We selfishly tried everything the vet offered to keep him alive, we were selfish because weren't ready to say goodbye to him. But we could see it was cruel and we owed him the dignity and peace that he deserved especially after he'd given us 17 years of love, loyalty and amazing memories.
I think Sam is doing the same thing and he's being selfish, but there's a huge difference between having a dog for 17 years and having one for a matter of weeks. - I refuse to watch because I can't watch an animal in pain or suffering.
