Has anyone here tried the Coyote Rollers?
Under Rover's Sitting Resources where they're talking about preventing escapes, is the statement, "consider purchasing Coyote Rollers, spinning cylinders that keep a dog from getting over a fence".
This is the first time I've heard of such a thing & since I have a long fence & this will likely be pretty expensive, I would want to know how hard it is to install, how well it works, etc.
Has anybody here tried this?
