My dog Badger died over a year ago, and I still miss him. He was my companion and friend.
He was getting on a bit when he died, twelve years old, and even though I didn't want to watch him grow old and die, I don't think he was ready to go.
He always had a worried look on his face, but I don't think he was really.
I don't believe in life after death but I think it would be nice to think that, when I die I would walk up to my father, and Badger would be running around us, without a worried look on his face, and the three of us would just go for a walk without talking.
