While speaking with the owners, the three dogs broke through the porch gate and aggressively ran toward responding deputies and fire personnel.

Less-lethal attempts to control the dogs were made by use of tasers and a fire extinguisher. One of the deputies then fatally shot one of the dogs.

A deputy suffered a dog bite and was treated at a nearby hospital. A second deputy who was reported injured declined medical treatment.
