New Hampshire designated the chinook as the official state dog in 2009. The chinook is a sled and work dog developed in New Hampshire during the early 20th century.
The chinook is the only dog breed originating in New Hampshire. Adopting the chinook as New Hampshire's dog symbol was the idea of seventh-graders at the Ross A. Lurgio Middle School in Bedford.
