When I was a kid...low these many years ago..we had a dog that killed snakes. When ever we went to visit GM at the farm, we took Brownie. He could even kill rattlers, must have been part mongoose. LOL He finally died of old age. Always felt safe with him around. Oh, and he liked to chase mice, too. But the house was a wreck when he did. Let nothing get in his way. I really miss that dog.
