Somehow a dog got off his property wearing a really thick chain. The dog menaced passer-by and police were called. The officer attempted to yell at the dog, telling him "no" and "go home". When that failed and the dog charged again, the officer shot the dog in the head. He ran back into his garage until animal control came and checked on him. HIs owner took him to the vet and he is expected to recover. The owner was cited for a loose dog and not having utd vaccines.
