Personally, I don' t have anything good to say about Invisible Fences, regardless of brand. Sometimes a dog will accidently " break through" and then won' t be able to get back in your yard. Some dogs actually learn how to " bust out" . They won' t keep other animals or the BIG Rottie from down the street from coming in and eating your dog.

Sure, a nice kennel run is more expensive, but there is nothing better for containment and protection of your dog.
