Our dog found 3 tiny bats in our umbrella earlier this year. Although he could not reach them he "treed" them like a squirrel and we could not get him to leave his "post" and come inside. We finally had to take the umbrella down and put it in the garage to get him back inside. We have tried to put the umbrella back on the table twice but he is sure those bats are still inside and refuses to budge in hopes that he will get his treasure! I don't mind having the bats around but they cause my dog to be, let's just say, less than obedient!
