This is Bella the airedale terrier. Bella is a bear dog. She works in a camp that is often visited by grizzlies. Since you can't shoot grizzlies, you better have dogs in a place like that. They will let you know when bears are around and will attack and chase a bear off without hesitation, barking and snapping at their ankles. When getting a bear dog, don't be tempted to get big breeds or bulldog types - go for quick and small dogs with a ferocious attitude, like shepherds or terriers.
