Not sure about this. Doesn't seem very comfortable for the dog. I added another layer of chickenwire to the fence that went outward so the coyote would not only have to jump up but then also to get over an overhang.No problems since then and cost maybe $50 and a few hours of work.
I live across the street from a big park where coyotes live. I see them walk around as early as 2-3pm sometimes - and a few times I saw them right outside my door late at night. My biggest worry is them jumping into my balcony and getting in through the doggy door, which they are known to do. My dog has no chance against them.
