Hope Lane tells KVUE-TV that her granddaughter forgot to shut the front door all the way after leaving for school, causing it to blow open, tripping the alarm.
Two officers arrived to Lane's home Friday, entering the house and shouting verbal warnings. Round Rock authorities say when they came upon the 120-pound Rottweiler named Bullet, the dog became aggressive toward them and made threatening actions.
That's when, according to KVUE, the officers shot Bullet a total of seven times.
The dog was taken away by police by the time Lane got back to her house.
