Grizz and Yukon are litter mates. But Grizzie is a playful teddy-bear like fluff ball with a different "mask" than his twin brother. Whereas Tundra and Glacier have the same mask, but different colors, Grizz and Yukon are hard to tell apart, except for their differing facial masks. You have to see it for yourself.
Grizzy and the pack are howling away!
