Like others said, an untrained dog is unpredictable. My dog is a prime example. I wanted a pet and got this specific rescue dog because I liked her. Obviously, one gets a package when one gets an adult rescue dog. She’s naturally aggressive toward:
- strangers of all ages from babies in strollers to seniors using canes and walkers; 1–3 year-old toddlers are her worst enemies.
- other dogs on leashes
- cats, birds, squirrels, small game like ducks, geese, and rabbits
- bees, ants, and anything else that moves.
When she tugs at the end of the leash barking fiercely at adult men or large dogs, I’m told she’s being protective of me. And I do feel safer going out at night with my dog at my side. But I have never felt the need for protection against babies and squirrels. Also, I don’t need a lawsuit because she mistakes a friendly handshake in the park as an assault and nips the other person’s hand.
The nipping has happened, as well as drawing blood; the lawsuit hasn’t but it could.
I have since taken measures to prevent the nipping and blood-letting. My point is that an untrained dog may well be protective but this “protection” may not always be in your best interest.
