Invisible Fence I have an invisible fence for my golden retriever (+120 pounds, one big boy), but I don't even put the collar on him half the time because he now knows the properties borders. I would never put it on my yorkie or a cat. They are just too small. I also live in an area with bears, coyotes, etc. with wildlife that could easily carry my yorkie away. She is only outside when someone is with her and that is the way it will stay. |
