Maricopa County Animal Shelters are giving away 1,000 free microchips to dog or cat owners on Saturday.
"This is just another way of encouraging pet owners out there to just really find that second alternative to make sure their pets are returned safely to them in the event that they get lost," said Andrew Greybear with the county.
Greybear said the first thing a shelter will do when they find a lost pet is to scan them for a microchip.
The free chips are being given away between 10 a.m. and 2 p.m. at the Outlets at Anthem.
The chips come with a free year of service and it's $17 per year after that to continue the service.
