Having lived in various country settings all over the country, I've found most healthy wildlife won't mess with a dog if a human is present..... usually. In fact, most problems I've experienced with animals on walks with the dogs have been with other dogs, usually feral or your disgruntled loose farm dog. Wild animals like bobcats will usually back off if you stand your ground. They don't see the point in getting injured by something that's going to put up a fight when there is other prey out there they could easily take down without getting injured. I use to carry a thing of bear mace, but given that doesn't always work, we got a non-lethal tazer.
