My g.f. Has a 12 lb miniature poodle, which is always on a leash. If a dog of larger size started attacking her on my own property u best believe i’m gonna kill the other dog before it has half a chance to attack her let along actually get to her. Dogs arent to be left outside on thir own without some sort of supervision. There just like kids and can become a liaability, so get your head out of your ass and keepyour dogs leashed ethered, and supervised. If You want a dog then be a fucking adult and except their responsibility.
