No responsible dog owner would, Lisa. I love dogs, grew up with AKC Dobermans, had three rescue pound puppies that were always well-contained during our marriage. Tom grew up with dogs and loved them far more than his parents ever did; he'd come home and his parents would have just gotten rid of his dog somehow. That devastated him. He loves dogs and that's why he doesn't want another one now, hurt too much when we had to euthanize our beautiful Kes at 15 years old.
This is a large brown dog, has Dobe-like markings, but is obviously a mixed breed, doesn't seem aggressive and probably is a nice dog on its own property, but he/she doesn't belong on my property and around my chickens. We have leash laws in Georgia as well as in my county; they mirror each other and these people need to know that they give me the right to prevent harm to my livestock, not just the right to shoot if they're being killed or have been killed.
My little ones have zero way to defend themselves. Even the largest, meanest rooster can't fight off a determined big dog, though most would do their best. We all know this, or anyone who has a clue does. I don't want to see that animal with my little Iris or Mace in his jaws or any of my birds. And Mace, that little whippersnapper, is shaping up to be a good rooster at almost 16 weeks old.
