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.
The German Shorthaired Pointer was developed in 19th-century Germany as an all-purpose hunting dog that could point, retrieve on land and in water, and track wounded game, basically a hunting Swiss Army knife.
The AKC recognizes only three Labrador Retriever colors: black, yellow, and chocolate. "Fox red" Labs are technically a dark shade of yellow, and "silver" Labs aren't accepted under the breed standard.
