What to do if your pet goes missing in Newmarket

  1. 1

    Search the area immediately, starting close to home

    Most lost pets are within a few blocks of where they escaped. Walk familiar routes, bring treats, and call their name calmly.

  2. 2

    Call local Newmarket shelters and animal control

    Use the Canadian shelter directory linked above. Many shelters keep found animals for only 72 hours.

  3. 3

    Post on Lost.ca and local community groups

    Lost.ca notifies neighbours in your area. Also share on neighbourhood Facebook groups and community boards.

  4. 4

    Check the Found feed on Lost.ca

    Most reunions happen because owners spot their pet in someone else's photo, not the other way around.

  5. 5

    Put up flyers nearby

    Print posters with a clear photo, your phone number, and the last seen location. Lost.ca's listing page has a built-in print button.

  6. 6

    Contact your microchip registry

    If your pet is chipped, make sure your contact info on file is current.

Shelters and rescues near Newmarket

Contacting local shelters is one of the most important steps in reuniting a lost pet. Many shelters only hold stray animals for 72 hours, so call the ones nearest where your pet was last seen as soon as you can. Lost.ca partners with humane societies and shelters across Canada, and many now post the strays they take in on Lost.ca too, which is why owners often spot their pet in this feed before the shelter calls.
