This is a video of a bear test in Japan. It is a tame bear, but note the blog author's translation about the judging: "The judge explains that it is an extremely important trait for a hunting dog to have a healthy level of cautiousness. If a dog attacks from the front with no regard for the superior power of the bear, the test is stopped as it shows the dog is lacking a healthy temperament for hunting". http://nihonken.blogspot.com/2011/09/hokkaido-ken-bear-test.html
