More facts about dogs.
Prairie dogs, those little pups popping in and out of holes on vacant lots and rural rangeland, are talking up a storm. They have different "words" for tall human in yellow shirt, short human in green shirt, coyote, deer, red-tailed hawk and many other creatures.
Snoopy, the famous dog from Charles Schulz's "Peanuts" comic strip, is a Beagle, which makes him probably the most famous Beagle in history.
The AKC breed standard calls for Rottweilers to have docked (shortened) tails, a holdover from their working past. Many European countries now ban docking, so Rottweilers there usually keep their natural tails.
