An adorable corgi has been caught mimicking the sound of a tornado warning siren as it was being tested. One-year-old Scout can be heard howling in reply to the severe weather warning system he may have mistaken for another dog. The footage was recorded in Rochester, Minnesota, during the annual test of the state's storm warning system. In the clip, Scout is seen gazing out of a window of his home when the tornado siren starts blaring. The youngster has never heard the sound before, and so is intrigued by the siren which could be mistaken for another animal's call.
