The house of a friend of mine was broken into. It was someone who went to every house in a neighborhood, broke whatever glass they could find with whatever was on hand (mostly paving stones) and went into the house. Dog didn't deter them at all. For his large (for the breed) black lab the burglar just grabbed a towel, waited for the dog to bite on it and then maneuvered the dog into a bedroom and locked the dog in there. Then ransacked the house in 5 minutes and moved onto the next house.
