A couple that just moved into their new home in the suburbs were told they ought to get a watchdog to guard their premises at night. So they bought the largest dog that was for sale in the kennels of a nearby dealer.

Shortly afterwards the house was entered by burglars, who made away with a good haul while the dog slept. The householder went to the kennel dealer and told him about it.

"Well, what you need now," said the dealer, "is a little dog to wake up the big dog."
