Did you know there is a dog museum? It's true! In St. Louis, Missouri, you will find The Dog Museum, founded by the American Kennel Club. There are paintings, sculptures, and other works of art that are about dogs or have dogs in them. Dogs have been in artworks that date back thousands of years!

People all over the world love to have dogs as pets. The United States and France have the most pet dogs. Almost one in three families in these countries own a dog. What countries have the least amount of pet dogs? Germany and Switzerland only have one dog for every ten families. They need more dogs!

Do dogs dream? If you look at your dog while it's sleeping, sometimes you'll see its eyes move and twitch under its eyelids. Humans do this too, and we definitely dream. So researchers are almost positive that dogs have dreams too. But guess what? No one knows what dogs dream about. Maybe the next time your dog wakes up from a dream, you can ask it!

Dogs are always smelling stuff. Wherever they go their snouts are sniffing. Why don't people do that? That's because a dog can smell a whole lot more than we can. Their sense of smell is about 1000 times better than a person's. Dogs can also hear a lot better than us. They hear high-pitched sounds (like some insects make), that we cannot even detect. Dogs need their good sense of smell and hearing because their eyesight is not as good as a human's. Do you know of any dogs that wear glasses?
