A man shot and killed his own dog after it attacked another dog in Hamden on Sunday.
Police responded to Brook Street and Wintergreen Avenue after getting a report of shots fired.
Investigators learned that the man was walking his dog off leash in a nearby park. A Hamden resident, who was with three children, entered the park with a dog that was on a leash.
Police said the man's dog, a pit bull, attacked the other dog and caused serious injuries.
The owner of the pit bull told officers that he thought his dog might attack the children so he pulled out his legally licensed gun and shot and killed his dog.
The investigation into the incident is ongoing.
