Several years ago a coyote scaled our 5 foot high wrought iron fence and tried to get our cat - the cat got away. I did a lot of research on how high of a fence coyotes can get over. Notice I'm using words like "scaled" and "get over," instead of the word "jump." I've talked with wildlife biologists and consulted animal control officials across the country. The height of fence they recommed ranges from 5 to 6 feet. However, I have been told of cases where coyotes have gotten over 10 foot high fences. I have personally seen (and videoed) dogs and coyotes going over 6 foot high fencing. And they get over by jumping to grab hold of the top of the fence with their front paws, and then pulling themselves up on top of the fence, and then jumping off. This is done in one smooth motion, and it happens so fast (1.5 sec) that it may appear that they actually jumped over the fence. On chain-link fences, some coyotes may have the ability to "climb" up to the top of a 10 foot high fence, and then jump off. As a result of my coyote experience I developed a product, called the Coyote Roller. There have been thousands of linear feet of this product installed and we have had no reports of coyotes getting over fences that are at least 5 feet high. You can see an illustration and download photos and video at http://coyoteroller.com/ So the answer is; coyotes can, in rare cases, "get over" up to a 10 foot high fence. They can routinly "get over" fences that are 5 to 6 feet high without some other way to impede their efforts, like the Coyote Roller. Their actual fence "jumpping" ability (i.e., going over without touching the fence) is probably about 4 to 5 feet. Keep in mind, coyotes also can dig under fences. Rick Sorben
