Dangerous Dog (Declared) laws in Massachusetts
Massachusetts General Laws Chapter 140, Section 157, outlines the legal framework for dealing with 'dangerous dogs' in the state. While the statute doesn't explicitly use the term 'dangerous dog' in the same way some other states do, it provides for the investigation of complaints regarding dogs that are a nuisance, a threat, or have attacked a person or another animal. Animal control officers or selectmen can investigate such complaints and, if warranted, order the dog to be restrained, confined, or even humanely euthanized. The law allows for a hearing process where the dog owner can present their case. The focus is on the dog's behavior and its potential threat to public safety, rather than specific breeds. Owners of dogs that have exhibited aggressive behavior must be aware of these provisions, as failure to comply with orders can lead to severe consequences, including fines and the loss of their animal. The emphasis is on preventing future incidents and ensuring public safety through local enforcement and judicial review.
