What can I do to a chain link fence to make it dog proof?
Coyote rollers, won't harm children like barb wire, is effective, and can be home owner installed.  




  A Coyote Roller is a patented ribbed roller that mounts to the top of your fence.  When a coyote or other predator tries to jump your fence to attack your pets, it requires them to grab hold of the top of a fence.  With Coyote Rollers in place, the animals will fall right off of your fence and will not be able to jump over.
