Frequently Asked Questions

I lost my pet. What should I do?

Take advantage of online platforms – they help you get the word out, quickly and easily. You can report your lost pet to PawBoost in no time flat. We'll send an email alert to our local members, post to the PawBoost-powered Facebook page for your area, add your pet to our lost & found, and make a lost pet flyer – all for free.

Other sites that help you raise local awareness for your lost pet with minimal time and effort are Nextdoor.com – a PawBoost partner – and Craigslist. Both of these sites have very active lost & found sections mainly used for lost pets. We highly recommend you use these resources in addition to PawBoost!

Visit your local shelters and animal control agencies in person. Details can get lost in translation over the phone and that might lead to missed connection.

If chipped, make sure your pet's microchip is registered and up to date. If you don't know your pet's chip manufacturer or number, your vet should be able to help locate this information.

Put up flyers and tell your neighbors to be on the lookout. The more you engage the Fontana community, the better your chances of a happy reunion!
