I would be afraid to try this.
Maybe I'm just a big baby... but every time I watched her do something that might make a dog want to go out into the street I was nervous. I would feel so TERRIBLE if I was trying to train this with Gordy, and he stepped onto the street at the wrong time
Plus, I kind of feel as though it is silly to say any dog has any behavior down 100% ever. I would never feel brave enough to throw a frisbee in the street in hopes that Gordy had learned an invisible boundary, no matter how great of a job he may seem to do. You never know when just the right distraction might come along at just the wrong time. I'd
never ever ever forgive myself if something bad happened to Gordy all because I thought I could trust an invisible boundary rather than put his leash on him to go out in the yard. It makes me feel awful just to think about it
Sigh
...
I'm a chicken.
On the plus side, Gordy knows that he can't go out any door without permission. Though I've never practiced that without a leash on... because WHAT IF for whatever reason he decides that even though he's stayed inside until given permission 10,000 times, he decides on the 10,001st time that there is a good reason to run out?
Also on the plus side, Gordy has a pretty fantastic recall... so if he should somehow get away from me, I can have a great deal of confidence that he will come back. But still... even if I can say that he's been 100% reliable on his recall since he's learned it, I don't feel as though I can say he always will be, no matter what may happen.
Growing up, I had a Golden Retriever who "knew the boundaries" of our yard. for years and years and years she stayed in the yard. One year when it had snowed, my mom was shoveling snow, and my brothers and I were playing with our Golden outside. This dog who had
ALWAYS always stayed in the yard, no matter what was going on, for some reason bolted from our back yard past our front yard, out to the road and in front of a truck!!! She got hit, and she was hurt really bad. It was the first time I'd ever seen a dog injured so badly. She just whimpered and whimpered. My brothers, my mom, and I were devastated. We loved our dog so much, and we felt so guilty that our sweet best BEST friend was hurt. We heard our mom that evening talking on the phone saying that she didn't know where we'd get the money to pay for the surgery our golden would need to fix her leg. I was 8, so my brothers were each a couple of years younger than me, and we all agreed, then told our mom, that even though Christmas was just around the corner, we didn't want
anybody: not mom, not relatives, not even
SANTA himself to get us
ANYTHING. We wanted our doggie to be better, so we wanted any money that would have been spent on our presents to go to our girl's surgery. I remember that being a LOT for my 8 year old self... so maybe I'm just always going to be afraid of another accident like that happening.
Our golden girl got her surgery, and was okay, but we never let any dogs free in an unfenced area ever again.
I do see the pluses for training this, but I just don't think this is a safe way to keep a dog confined to an area.
