Here are some quotes about dog death that I found:

- "The bond with a dog is as lasting as the ties of this earth can ever be. The one best place to bury a good dog is in the heart of his master." - Ben Hur Lampman
- "I guess you don’t really own a dog, you rent them, and you have to be thankful that you had a long lease. The reality is that you will grieve forever." - Joe Garagiola
- "Dogs leave pawprints on our hearts." - Unknown
- "A good dog never dies. He always stays. He walks beside you on crisp autumn days when frost is on the fields and winter’s drawing near. His head is within our hand in his old way." - Mary Carolyn Davies

I hope these quotes help you in your search for comfort.
