Blue was a white Bull Terrier owned by hockey commentator Don Cherry.[1] Blue was reportedly a gift from the members of the Boston Bruins when Cherry was their head coach from 1974 to 1979. The original Blue, who died in 1989, was actually a female.[2] Cherry has since owned other white bull terriers, all of which were named Blue.
The dog often starred in Cherry's annual series of hockey videos called "Rock'em Sock'em". Bones, the mascot of the Niagara IceDogs, formerly the Mississauga Icedogs, which Cherry partly owned, is modelled on Blue.
Cherry and Blue are the spokespeople for the CherryBlue Pet Insurance [1] program in Canada.
