State police say a man shot and killed a dog at the Hooksett Rest Stop on I-93 Wednesday afternoon, after it attacked his own dog in the parking lot.
The incident occurred at the northbound rest stop, when, according to police, a large dog broke free from its owners through an open window of a parked car, and attacked a smaller dog.
Witnesses say a man, who police did not identify, made several attempts at freeing his dog from the larger dog's jaws. When that failed, he fired a single shot at close range, killing the animal.
The smaller dog sustained injuries from the attack, and was taken to a local veterinarian for treatment.
The incident is under investigation.
