Action starts around 4:35

Police in Commerce City, Colorado shoot and kill a large dog that was
wandering around in the streets of the major Denver suburb. The two
officers said that was the only course of action they could take after
it tried to attack them. You can see two police officers and a member of
animal control backing down a large, black dog into an open garage. The
woman from animal control appears to be holding a snare pole, while the
two officers give the dog a wide berth.
