A toy landed on a Trayer Road lawn first. Then, a witness told authorities, a small dog was pushed from a silver SUV before the driver pulled away. The dog is now safe at Canton Animal Control, but the person who left him and whether that person owned him remains unknown.
The incident was reported at about 9 a.m. on Tuesday, Nov. 3, in Canton, Massachusetts. The witness described the driver as a middle-aged woman and the vehicle as a silver Toyota RAV4 believed to be from model years 2019 through 2025, based on its body style.
An animal control officer recovered the dog from the area, along with a blue and orange Nerf dog ball reportedly left at the scene. The small adult male, believed by animal control to be a Cairn terrier mix, appeared dirty but had no obvious signs of injury or distress. He was taken to the Canton Animal Control shelter, where he is receiving care.
The dog wore a collar, but it carried no identifying tag. A scan found a microchip, offering investigators another possible path to his history. That path was not a direct one: The chip had never been registered, so it did not immediately connect officers with an owner.
A microchip number can still leave a trail
A pet microchip is not a GPS tracker and does not contain an animal’s medical history. As the American Veterinary Medical Association explains, it carries a unique identification number that appears when the chip is scanned. Registration is what links that number to contact information.
An unregistered chip can nevertheless provide a starting point. The American Animal Hospital Association’s registry lookup tool can identify companies that manufactured or sold a chip, although it does not disclose an owner’s information. Shelters and investigators may also contact the manufacturer or the organization that implanted the chip to look for older records.
In this case, animal control is working with a North Shore veterinary clinic to trace the dog through historical veterinary records. That effort may help establish his identity or ownership, but authorities had not announced a result. They also had not determined whether the SUV’s driver owned the dog.
Why adoption inquiries must wait
Several people have called about adopting the terrier mix, but he is not available. Canton officials said the investigation must continue and a mandatory 10-day stray hold must be completed before his status can change.
Massachusetts’ broader animal-placement guidance says stray dogs must be held for seven days to give rightful owners time to reclaim them. The same guidance directs animal control officers to search for an owner in every case. Canton has identified a longer 10-day hold for this dog, and the active investigation adds another reason adoption inquiries cannot yet proceed.
If no owner comes forward, Massachusetts guidance allows municipal animal control programs to return, adopt, transfer or, when necessary, humanely euthanize animals under specified conditions. It also calls for health and behavior assessments before adoption or transfer. Canton officials have not announced which path would apply here and said they will share information if and when the dog becomes available.
For now, police are asking Trayer Road residents to check recordings from the morning of Nov. 3, particularly for a silver Toyota RAV4 or activity connected to the incident. Anyone who witnessed what happened, recognizes the dog or has relevant identifying information can call Canton Animal Control at 781-575-6507 or Canton Police at 781-821-5090.
The unanswered questions still circle the small dog: what name he knew, where he lived and who was responsible for him. Investigators are still following those threads. Meanwhile, behind the shelter doors, he is no longer alone on a lawn. He is safe.
