Clear the Shelters is a national campaign that encourages people to adopt from their local shelters in an effort to “clear the shelters.” The campaign receives national and local coverage on NBC and each year over 100,000 animals are adopted from participating shelters and rescues.
The event was held on Saturday, August 16, 2014, under the name Empty the Shelters, and it was even bigger than expected, with the 33 participating shelters adopting out 2,256 animals. Dallas Animal Services ran out of adoptable pets by 2:30 PM. One shelter adopted out more animals on that day than it had in the entire month of August in the preceding year.
