:bigthumbsup: I can't say enough GOOD about the invisible fence. If it fails to work on some dogs it's because the probes on the collar aren't reaching the skin. They come in 2 different lengths. Goes without saying that long haired dogs require the long probes. Also if it doesn't work the battery in the collar is dead. Replacement batteries may be purchased at Radio Shack. Our Irish Setter has been on one for 4 years. There's 2 styles of invisible fence. One that you bury a wire around the perimeter of your yard and plug it an electric outlet. OR you can purchase a unit that plugs into your house and shoots a signal out from your house via your electric wiring. This would be great if you didn't have to worry about your neighbors property. I suggested this unit for my son in laws 2 dogs. I think with 2 collars it was under $300. You can buy it at Lowes or Home Depot. Matter of fact you can get either units. The animals catch on quick and eventually you won't even have to have the collar on them. To have the underground unit installed they want to rob you. Don't be surprised if the cost is over $1,000. I rented a sidewalk edger for a day ($28) and set it to the deepest setting and went around my yard making a small trench. Then I walked along and shoved the wire in the opening in the ground. My cost was about $350 but I used 1100 ft of wire. I did not put it inside conduit. You also should notify the utilities to make sure you don't cut any of their lines. I hope this helps or gives you an idea of what you're up against.
