Research has shown that they can scale up to 14 feet and that it's at the 6 foot mark where they need use leverage to get over. Fences or walls lower than 6 feet risk the Coyote simply jumping over it without ever touching the top. This why we recommend at least a 6ft fence to install your Coyote Rollers.
The "jump" consists of two phases. First, the Coyote jumps to grab hold of the top of the fence with its front paws. It then adds to it vertical momentum by pulling on the top of the fence, this allows him to gain additional height. At the same time he brings his back paws up to the top of the fence, so at that one moment, all four of his paw are in contact with the top of the fence or wall. All of this takes less than 1/2 a second! Next, the coyote then uses his back legs to spring off the fence, while he extends his front paws in preparation for landing. The Coyote Roller interferes with the first part of the jump by making it impossible for the animal to grab the top of the fence.
Coyotes can grab and carry an animal that weighs up to 25lbs over a 6ft fence. They are capable of digging under a fence but they are opportunistic and generally take prey that is the fastest, easiest to secure. I have heard from people that have had Coyotes attack not only small dogs, but also larger dogs! A loose dog (or cat), no matter their size, is at risk for being killed by Coyotes. They will attempt to engage a loose dog in a friendly, sometimes playful manner to get the dog to follow them towards awaiting pack members, to kill them. This is why small pets are at risk inside your yard, and loose dogs of any size are in danger when off your property. Fortunately, if you have Coyote Rollers installed on your fence, this danger is greatly reduced!
