Instead of a guard dog, you need Bigfoot lurking behind a tree. Sure, he can’t chase and bite like a yappy little dog, but he can give that dark lurking stare. Just hang him on a tree somewhere around your property and it’s bound to make the ocasional person jump or at the very least get a small giggle. These can be attached to trees that are over 11” diameter trees. These cost $69.95 through Toscano Design.
