It's wild to me how some dogs just know how far out in the yards they can go with no fences or gate. A neighbor has a 14 year old pup that doesn't even need to be leashed to know to stop at the curb. Although I do believe all dogs should be on a leash due to traffic and little children not all are violent creachers out to harm humans that aren't leashed.
Also, I just realised they give out the most humongous type of capacitive stylus, let's just say it probably wouldn't fit in your pocket
