<p>Basically, you cannot trust any fences for children or pets. The idea that you can put either of them outside and then forget about them is madness. Never mind the trouble they can get into in the yard, but, yes, they CAN get out, regardless of what you kind of fence you have. We were negligent in the use of our fence with our Lucky who very thoroughly taught us the reliability of any fence. With our subsequent dogs, we have not bothered with a fence except as a training tool.</p>
<p>There was a wireless system on the market that I think is great in teaching pets the borders of the yard. By restricting our dogs to a certain part of the yard to do their business, we had less clean up issues. We had 3 dogs at one time, so that was a big issue. We let the dogs romp in the front yard under close supervision only–when someone is directly with them. We let the out the back and watch them even with the electric fence. We NEVER just let the dog out and take our eyes off of them. I’ve told the kids that the dogs are like toddlers. You cannot just let them loose in the yard. So the fence was put into use, just so that the dogs quickly learned the ground rules of where they can go in the yard which makes gardening easier as well as clean up, but we do not rely on it at all. In fact, they did not even wear the collar after training as it really wasn’t that important if they went out of the borders. </p>
<p>So getting an invisible fence can serve as a very strong and quick way of teaching the dog to stay in the yard, But it is not a reliable thing to use to just let your dog out and not keep an eye on him.</p>
