Dog saves owner from bear attack

[Catherine]

Boomer is one brave dog. She tackled a full sized brown bear and drove it off. With out her intervention her owner would have been killed.

Think about it, the bear was 300 pounds, the dog was thirty pounds. Boomer drove of an attacker that was ten times her own weight. That took incredible courage and loyalty.
Once again a dog proves to be our best friend.
