Rescue centers that adopt pets usually go through a lot of effort to ensure that the pets they adopt out are a good match for the new owners. They check the pet's temperament against the new home, they check to see if the pet is high or low energy, if they're good with kids and if they get along with other animals. One aspect they tend to miss, however, is to check a dog's IQ. Nobody expects their next pet to be an Einstein, but it would be nice to adopt a pet that can at least remember where the food bowl gets put down every day.
