A Halifax Regional Police officer shot a dog early Sunday morning on Portland Street in Dartmouth.

Police say in a release that officers were doing surveillance on a home in the 300 block as part of an investigation when one was charged by two dogs around 4:30 a.m.

Police said the officer fired three times at the dogs. One of the dogs, a bull terrier, was hit and both went back into a residence.

Someone called 911 and said the dog had been shot. Police took it and the owner to an emergency veterinary clinic.

Police said the dog was alive when it was taken to the vet.
