I didn’t want to take over the Invisible Fence thread as this is not a time-sensitive solution for the OP’s issue.
Some posters have brought up that they have both a physical fence and an Invisible Fence (or other electric equivalent) set inside of it as backup.
For those of you who have it, how tall is your physical fence, and how bull-headed is your dog? How well does the two-fence combo work to keep the dog in?
If a rabbit runs outside the physical fence, does the combination of invisible fence + physical fence stop the dog from going after it?
We will need to make some fencing improvements on any property we buy and had planned on a 4’ fence (maximum allowed by any local HOA) plus a very stout hedge to deter leaping, as we have an athletic and high-drive dog whose legs turn on well before her brain does. I had not considered adding invisible fence as a backup. We had it growing up for my parents’ pack of dogs. The Golden Retrievers would go through it, but probably would not have jumped a fence. The Pyr would dig under a fence but didn’t challenge the Invisible Fence. The Husky was blind, deaf, neurotic, and sort of feral, and went where she pleased, so nothing would have kept her in, but the combination would probably have worked for the others.
