First steps if you lose your dog in Thornton

  1. 1

    Search outward along roads, paths and fields — a dog can cover several kilometres in the first few hours.

    Tip from locals

    Search outward along the Colo Agri Canal, about 1.2 miles away, then Spratt Lake Fishing Area, roughly 2.6 miles out, since a dog can cover a lot of ground in the first hours.

  2. 2

    Call the shelter, the local police and nearby vets straight away: a loose dog is usually picked up and handed in quickly.

    Tip from locals

    Two vet practices are within about 3 miles, so call them straight away and ring the local police too.

  3. 3

    Ask people not to chase or shout — a frightened dog runs. Crouch down, avoid eye contact and call calmly.

    Tip from locals

    Ask dog walkers in Margaret W. Carpenter Park & Open Space, about 2 miles away, and Carmenisch Park, also around 2 miles, to watch and call rather than chase.

  4. 4

    Leave something carrying your scent, plus water, where he went missing, and check back regularly.

  5. 5

    Report him to the microchip registry and start a targeted alert that reaches the whole neighbourhood at once.

    Tip from locals

    Northglenn, about 1.4 miles north-west, and Sherrelwood, around 2.6 miles south-west, are the neighborhoods a dog may already have reached.
