There are always a few rare breeds rising in popularity. Proceed with caution! Many of these up-and-coming breeds are hunting or guard dogs. Do you really want a dog around who was created to, and whose parents loved to, kill bears? Do you have a bear problem? Black bear in your basement? Grizzlies in your garage?
If you do NOT have a bear problem then you do NOT need this breed. Choose a family companion to do what you need him to do every day of his long life - love your kids and chase a tennis ball.
Large, powerful breeds naively bought for some perceived need for protection too often end up injuring family members, often the children, more frequently than they save lives.
