French Bulldog

The French Bulldog has held the title of the most popular dog breed in the US since 2022. Their friendly and adaptable nature, combined with their small size, makes them perfect companions for people living in apartments or smaller homes. They may snore a little when they sleep, but that only makes them even cuter.

Just be cautious around water. Despite their bold personalities, French Bulldogs are not strong swimmers. So it’s important to supervise them closely near pools, fountains, or any other body of water.

2

Labrador Retriever

In second place, we have the beloved Labrador Retrievers, who were surpassed by French Bulldogs only in 2022. For more than three decades, the sweet Labrador was America’s favorite dog, and for good reason.

Known for their outgoing and gentle temperament, they get along wonderfully with adults, children, and even other animals. Their intelligence and sensitivity also help them stand out not only as loyal family pets and hunting companions, but also as therapy and service dogs.

3

Golden Retriever

Right behind Labradors are Golden Retrievers, the good guys of the neighborhood. With their warm temperament and endless energy, they’ve earned the number three spot among the most popular breeds. Often described as "people pleasers," Goldens are more than just obedient; they’re quick learners who are always eager to join you on any adventure.

4

German Shepherd

Fourth on the list are German Shepherds, elegant, impressive dogs renowned for their loyalty, intelligence, and ability to learn quickly. Unlike Labradors and Golden Retrievers, however, they often have a more serious image, largely because they’re commonly associated with police work, search and rescue, and service roles. Naturally protective, they tend to be reserved at first but become affectionate with those they trust.

Do you remember Rin Tin Tin? He was a great example of the breed and helped bring German Shepherds to worldwide fame.

5

Poodle

It’s hard to write a paragraph about Poodles, not because we don’t have anything to say, but because it’s easy to be distracted by all that cuteness. Ranked fifth among the most popular breeds, Poodles also rank among the most intelligent dogs in the world. Their extraordinary smarts and enthusiasm to learn come from their history as skilled hunting dogs and even circus performers. Thanks to their obedience, agility, and strong bond with people, they continue to hold a top spot among America’s favorite breeds.

6

Dachshund

In sixth place are the adorable Dachshunds. Famous for their long bodies, short legs, and big personalities, these dogs weren’t in the top rankings a decade ago. Many believe their surge in popularity has been fueled in part by viral internet videos showcasing their charm and humor. But don’t let their small size fool you: Dachshunds may be small, but their deep, bold bark makes them sound much bigger than they really are.

7

Beagle

Beagles come in seventh place, though if there were a contest for best ears, they’d surely take first. They’re loved not only for their adorable looks but also for their intelligence and, above all, their extraordinary sense of smell. Originally bred as rabbit-hunting hounds, Beagles have a highly efficient nose and a powerful tracking instinct.

8

Rottweiler

With their striking appearance and muscled bodies, Rottweilers naturally command respect. Known for their loyalty and strong protective instincts, Rottweilers are a favorite among families who have enough space for these large, energetic dogs.

Did you know they’re considered one of the oldest surviving dog breeds? It’s true! Their ancestors are believed to have accompanied the legions of the ancient Roman Empire, where they were used to herd and guard livestock.

9

Bulldog

They may have a grumpy look, but Bulldogs are incredibly sweet and calm. Ranked number nine on the list, this lovable breed is a great choice for anyone looking for a dog that easily adapts to their home and lifestyle. While they’re not exactly lazy, Bulldogs do enjoy taking plenty of breaks and conserving their energy, often choosing a cozy spot on the couch over a run around the block. Plus, with those funny faces, you’ll never run out of excellent pictures.

10

German Shorthaired Pointer

Last on this list, but still among the most popular breeds in the country, the German Shorthaired Pointer is admired for its elegance and presence. Originally bred in Germany as versatile hunting dogs, this breed excels at pointing, retrieving, and tracking. With their boundless energy, German Shorthaired Pointers are best suited to homes with plenty of outdoor space, as their athletic build and enthusiasm also help them shine in a wide range of dog sports.

What are bills made of?

Unlike other currencies, dollar bills are not made of paper or plastic. U.S. dollar bills are made from a special fabric blend composed of 75% cotton and 25% linen. This mix makes the bills extremely durable and resistant, and they can be folded about 4000 times before tearing.

2

What bills are valid?

Any U.S. dollar bill that was legally printed is valid, no matter how old, as American currency does not have an expiration date. While some bills might not be accepted by businesses of foreign exchange services due to their condition or if they are a discontinued version of the bill, the bills themselves are still valid, and American banks will accept them, though they might take them out of circulation.

3

American leaders

Five bills have a depiction of an American president. The exceptions are the $10 bill, with Alexander Hamilton on the front, and the $100 bill, with Benjamin Franklin. The $1 bill, depicting George Washington, is extremely symbolic: several elements are repeated 13 times as a nod to the thirteen colonies, and it showcases the Bald Eagle and the Eye of Providence as a sign of God watching over America.

4

A change in size

Did you know that dollar bills used to be so big that they were nicknamed "horse blankets"? Original dollar bills were 7.4 × 3.1 inches. In 1929, the Treasury Department reduced the size of bills to 6.14 × 2.61 inches to reduce production costs and materials. Old bills, though still valid, are worth much more as collector items.

5

Uniformity

Besides their value and design, all dollar bills have the same size (6.14 × 2.61 inches), color, and weight (1 gram) , which sets American currency apart from other countries where bills of different values are differentiated by size, color, or both. Why doesn’t the U.S. implement differences among bills? The cost of adapting vending machines, bank drawers, and ATMs to new bill sizes would cost billions of dollars.

6

Hard to copy

Originally, dollars were not green, but black. As time passed, green ink was favored, as it was cheap and did not fade as much as black. The new color also prevented people from using black-and-white cameras to create counterfeit money. Currently, dollar bills are predominantly green, but newer versions also include extra colors, such as pink, orange, or purple.

7

A $100,000 bill?

Have you ever seen a $500 or 1,000 dollar bill? What about a $100,000? Up until 1945, the U.S. Treasury printed $500, $1,000, $5,000, $10,000, and $100,000 notes , in addition to the values currently in use. These higher-value notes were mainly intended for bank and government use, but were sought by criminals as they made it easier to hide large amounts of money. Even though they were officially discontinued in 1969, these notes are still valid, though rare, and they have a high worth as collector's items.

8

No numbers

Unlike bills, American coins have different sizes and colors related to their value. Originally, gold, silver, and copper were used for coins, but modern coins are made of copper, zinc, or nickel. Besides their size and design, the value of each coin is printed in letters, not in numbers , alongside depictions of American presidents.

9

Liberty for all (the coins)

By law, all American coins must include six specific details : the word ‘Liberty’, the name of our country, the national motto "In God We Trust", the oldest American motto "E Pluribus Unum", the value of the coin, and the year. Each coin also includes a mint mark that shows where it was made: "P" for Philadelphia, "D" for Denver, "S" for San Francisco, and "W" for West Point.

10

A global currency

The American dollar is one of the most powerful currencies in the world, acting as a backbone for international trade and finances. It is estimated that two-thirds of the physical dollars in circulation are outside American territory. Besides the U.S. and its territories, eight sovereign nations have the U.S. dollar as their official currency, with several more accepting it as legal tender.

There's an unexplained billion-year gap

Look closely at the canyon walls, and you'll notice something strange: a clean, sharp line where ancient rock simply stops, and a much younger layer begins directly above it.

This geological puzzle is called the "Great Unconformity," and it represents over a billion years of rock layers that are simply absent , as though that stretch of time never happened. In some spots, rock dated 1.8 billion years old sits directly beneath rock that is only 520 million years old. Where did the missing billion years go?

The leading theory involves the violent breakup of an ancient supercontinent, but scientists are still piecing it together.

2

During the Cold War, it hid a nuclear fallout shelter

During the Cuban Missile Crisis in 1962, the U.S. government converted part of the Grand Canyon Caverns into a fallout shelter. This dry cave system, more than 200 feet underground, was stocked with enough food and water to sustain 2,000 people. Naturally, it was never occupied, and the supplies were never used.

The caverns have since been transformed into a tourist attraction, with organized tours winding through the same underground chambers that were once intended as a refuge from nuclear war. You can even book a night's stay there.

The Federal Aviation Administration was founded after a crash over the canyon

In 1956, two commercial passenger planes collided in midair over the eastern Grand Canyon, killing all 128 people on board both crafts. Rescue teams struggled to reach the wreckage deep inside the canyon, and the extreme heat of the crash had caused the planes' aluminum to fuse with the bedrock. There were no survivors.

The disaster exposed a terrifying truth: the U.S. air traffic control system was dangerously outdated, relying on pilots' visual estimates and rough guesswork from controllers , with no way to separate fast-moving aircraft from slow ones, or instrument-flying planes from those navigating by sight. Congress responded by passing legislation that created both the Federal Aviation Administration (FAA) and the National Transportation Safety Board.

4

A hoax suggested that an Egyptian civilization had lived there

In 1909, the Arizona Gazette reported that an explorer named G. E. Kinkaid had discovered a vast underground citadel inside the canyon, filled with artifacts linked to ancient Egyptian civilization. He even claimed the expedition had been funded by the Smithsonian.

This story described hieroglyphics on the walls, mummies in the chambers, and relics pointing to a direct connection with the Egypt of the pharaohs. It was incredibly detailed, and it was, of course, a hoax. No evidence for any of Kinkaid's claims ever surfaced.

5

Fewer than 100 people have ever hiked its full length

Among the few people who have completed the through-hike of the Grand Canyon is Jen Hogan, the first woman to accomplish it, finishing her journey in 2021–2022.

It’s a full 800-mile length below the rim. The route involves extreme heat, flash floods, near-impassable areas, and stretches with no water or trail whatsoever. Around 60 or 70 people have reportedly accomplished it. This makes it one of the most exclusive feats on Earth.

6

The Grand Canyon's rocks predate dinosaurs entirely

Visitors scanning the canyon walls for fossils are often surprised to learn they won't find any dinosaur bones here. The rock layers of the Grand Canyon are simply older than dinosaurs. This fact alone can be shocking: staring at its walls means staring at marine fossils from as far back as 1.2 billion years ago. Some of its caves hold the remains of ancient mammals. The canyon is a window into a world that existed long before the dinosaurs, when the land that is now Arizona lay beneath a shallow sea.

7

The park is bigger than Rhode Island

Numbers alone rarely capture the Grand Canyon's scale, so here's a different approach. Rhode Island covers about 1,214 square miles, and the Grand Canyon National Park spans 1,904 square miles.

The canyon's depth exceeds four Empire State Buildings (which is 1,454 feet) stacked on top of one another. That’s 6,093 feet at its deepest point.

8

But it's not the deepest canyon on Earth

For all its grandeur, the Grand Canyon does not hold the depth record. Pictured above, the Yarlung Tsangpo Grand Canyon in Tibet, China, plunges to 17,567 feet, which is nearly three times deeper. Carved by the Yarlung Tsangpo River as it cuts through the eastern Himalayas, that canyon is so remote and extreme that it remained largely uncharted until the late 20th century.

9

It is home to a pink rattlesnake found nowhere else on Earth

The Grand Canyon Pink Rattlesnake has a pinkish-red coloring that matches the canyon's own distinctive rock walls so closely that it's nearly invisible. It is found nowhere else in the world. Officially classified as Crotalus oreganus abyssus , it has darker diamond-shaped markings along its back that deepen the camouflage further.

10

There's a village at the bottom: Supai Village

For over 1,000 years, the remote village of Supai has been home to the Havasupai Tribe, the People of the Blue-Green Waters. It is located an eight-mile hike from the rim, but sits roughly 3,000 feet deep inside the Grand Canyon.

The U.S. Department of Agriculture has called it the most remote community in the contiguous United States, and it has no automobiles and no road access. The only ways in are on foot, by mule, or by helicopter. It is also the only place in the United States where the postal service still delivers mail by mule train.
