No. Massachusetts General Law, chapter 140, section 174F, prohibits the confinement of any animal in a motor vehicle when extreme heat or cold could reasonably be expected to threaten the health of the animal.
If a person finds an animal in a motor vehicle, he or she must make reasonable efforts to locate the motor vehicle’s owner. The person cannot enter the motor vehicle to protect the health and safety of the animal unless the person notifies law enforcement or calls 911 before entering the vehicle. If the vehicle is locked, the person must use reasonable means to retrieve the animal. The person must also have a good faith belief that entry into the vehicle is necessary to prevent imminent danger or harm to the animal. Finally, the person must remain with the animal after retrieving the animal in a safe location near the motor vehicle until a responder arrives.
