From Best Friends Animal Society:
Can your local homeless pets count on you to be among the many thousands of people checking in across the country for National Animal Shelter Check-in Day?
Learn how you can help!
Use a geo-location app on your mobile phone, like foursquare or even Facebook places, to “check-in” from your local shelter. Maybe even take a photo of a pet there and post it on social media to help promote adoption.
Voila! Helping a homeless pet find love has never been so quick and easy!
