Statistics do not agree when it comes to determining if there are more pet cats or dogs in the U.S., but statistics about dog-owners are clearer. For example: Dog-lovers are deeply attached to their own dog and its breed, but tend to think every dog is adorable, no matter what breed. They will stop to pet any pooch they see, which is why walking a dog is a great way to meet people. (It’s much harder to walk a cat.) Still, you may not know as much as you think about dogs.
