I'm so sorry for your loss. Nanook was lucky boy to spend his life with someone who loved him so deeply. Know that he took that love with him to the next world, that he remembers and that he waits for you. You will see him again.

There is a version of the Rainbow Bridge poem just for Northern Breeds.

I am sure that Nanook is playing in the snow, happy, healthy and young again. Godspeed, Nanook. Look for my Hoodoo, he'll show you around the North Bridge.
