Diefenbaker is Fraser's closest friend after Ray. The wolf/dog pulled Fraser from an ice flow, and apparently his eardrums burst. We say apparently because Dief seems to have selective deafness, especially when Fraser is giving him orders. Dief's mate is a husky named Maggie, and we as yet do not know what their pups were named. Dief is walked and fed during the day by Willie, a young boy Fraser took under his wing in the first episode of the series. Dief can easily escape Willie when he wants to. Dief was named for Canadian PM John Diefenbaker.
