Winchester Police Investigating Fatal Dog-on-Dog Attack

Winchester Police are investigating a dog attack in which a Bull Mastiff attacked a puppy on Squire Road on Sunday afternoon.

Police were called to Carriage Lane shortly before 4 p.m. Sunday. The resident said she was walking her puppy on a leash when the Bull Mastiff attacked her dog.

The puppy’s owner took the dog to a Woburn animal hospital where it died.

Winchester Police and Winchester’s animal control officer “determined that the Bull Mastiff got away from its owner and attacked the much smaller puppy. The investigation also showed that the alleged aggressor dog has been the subject of multiple previous and subsequent complaints about aggressive behavior in Winchester and previously in Woburn where it formally resided,” said Winchester Police.

Police told the owner of the Bull Mastiff that he must turn over the dog for a mandatory 10-day quarantine period during the investigation, but he has not done so. Police are ”considering its legal options, in the interest of public safety,” according to the police.

“This is a very sad story for all involved,” said Police Chief Kenneth C. Albertelli. “We hope that all parties involved will cooperate with police and allow the investigation to run its course. Our only concern is for the safety of all human and animal residents of Winchester.”
