I have a red healer that is one of the best ever. He watches after my bee hives all the time. We have a problem with black bears trying to get free honey. Got so bad I had to invent a bear alarm to chase them away. That dog hates bears and will bite them on the back side and hind legs. When the bear turns to hit the dog the dog stays behind the bear where the bear can't reach. Then The bear soon gives up. The dog will chase the bear over the mountain top.
