All 4 of my yorkies have invisible fence collars. Invisible Fence has very small collars that are not obtrusive, even on my 3 pounder. They are set to the lowest shock level & they each have been shocked only once. That's all it took. We have a 4-lane highway behind our property & they will chase rabbits out of our yard but they know right where to stop so they don't get zapped. It allows us all to be outside together, they can run & chase, we can play fetch, all without the entanglement of tie-outs. They are NEVER allowed outside unsupervised as we have hawks & fox in the area. They are able to fully enjoy their yard and remain safe. I would never solely rely on the invisible fencing, though. As I said, we are always out there with them. |
