Let's face it folks. ALL dogs are animals and they all have undesirable traits.
My neighbor had a Sheep that was rejected by its mother, so he put it in with the Dogs. Of course he imprinted on the Dogs, and he followed them everywhere. Even learned to bark instead of bleat.
Time went along, and one day I noticed that the Sheep was missing, so I asked him what happened to it. He said, sadly, "I
had to shoot it, damn fool thing started killing Sheep."

I've owned all kinds of dogs from Mutts to pure bred and I never owned a Mutt that had the brains God gave a louse. Our present dog, Seamus, is the smartest one of all and he even has a sense of humor.

Bobert, where I live it is illegal to allow dogs to chase Deer. If you have a Groundhog problem a Dachsund is the answer. If you have Bears, a Bull Mastiff is the ticket. I dont know if Bears laugh or not but the sight of a Dachsund trying to run one off would probably do it.
You need half a dozen dogs.One for each critter.
