One thing that sold me on the CYV vs the others was the floor plan. I like the living room area being in the back and no windows in the front. All windows look into the private yard area except the 2nd bedroom window which looks out front.

Studies say the Invisible Fence is 70% effective. The number to be concerned with is the other 30%. We love our dogs and look for what is best. Good luck on your search!
