Has anyone tired the wireless fences with there dogs?  I have 25lb Decker and I am considering one of these fences.  I would like to stick with the wireless fence if possible so I could carry it with me when I go to different places.

I already have a fenced in back yard but would like to be able to go in the front or side yards without him on a leash.  I have no experience with the wireless or wired fences except holding onto a collar to see how strong the shock was.  My dog is a very prey driven dog.  Will one of these fences contain him?

We had an invisible fence one a long time ago. Our bird dog Cocoa would run right through it to chase squirrels, but wouldn't cross it to come back home, and our lab mix would never cross it.

I have to tell you a little story about our walk yesterday though. We walk by 2 airedales in our neighborhood that are contained by an invisible fence. We've walked by them for years with no problems, and yesterday one of them crossed the fence and ran out into the road as we were walking by. I don't think he had his collar on, however.

One other thing I have noticed over the years is that if there are loose dogs in the neighborhood, as there often are in our neighborhood, these airedales are not protected by a fence. The loose dogs can go right up to them. I've seen stray dogs off and on over the years in our neighbor's yard with their airedales.

If they do go outside their perimeter, it will shock them for 30 seconds or until they come back inside the perimeter.  The 30 seconds, is so that if a dog were to get out and NOT understand to come back in, it won't get shocked for however long it takes for someone to figure out the dog is out. (did that even make since?)
