Hint: This independent dog grooms itself like a cat and emits piercing screams when unhappy.

There are currently about 340 different dog breeds around the world, but only 205 are recognized by the American Kennel Club. Some are easy to identify when you see them on the sidewalk or at the dog park, like a pug or corgi, while others, like the Sloughi or otterhound, are less well-known.
The popularity of different breeds changes over time and based on global location, but there are certain types of dogs that have lasting appeal, at least here in the U.S. When the AKC released its ranking of the most popular dog breeds in March 2026, the French bulldog secured the #1 spot for the fourth year in a row. Prior to that, the Labrador retriever had held the #1 position for an impressive 31-year run.
Golden retrievers, poodles, German shepherds, beagles, dachshunds, and bulldogs have also sat comfortably in the top 10 for the past six years. As a result, these breeds tend to be the most unmistakable, which is also thanks to some distinctive features, like a poodle's curly locks or a dachshund's long body and short legs. Other, more uncommon breeds are much harder to identify at a glance without the benefit of knowing their distinctive behaviors or hearing their barks.
Here, Stacker is testing your canine knowledge. Can you guess these 20 dog breeds from just the shape of their outline?

2 / 41Answer: Shiba Inu
The Shiba Inu (Japanese for "brushwood dog") is a very independent breed. Thanks to this, the dogs are next to impossible to train; however, what they lack in obedience, they make up for in loyalty. After the 2004 Chūetsu earthquake, a Shiba Inu helped rescue workers locate her elderly owner, who was trapped beneath the rubble. The ordeal was adapted into a movie called "A Tale of Mari and Three Puppies."

Basset hounds have also been frequently featured in pop culture, including Walt Disney animated films and a variety of television series, such as "Columbo" and "The Dukes of Hazzard."

24 / 41Answer: Belgian Malinois
The Belgian Malinois is known for its exceptional tracking abilities. These dogs can detect odors, hunt down suspects, and locate injured persons more effectively than most other breeds in search and rescue missions. Because of this, these dogs are used by the Secret Service to guard the White House grounds. The breed's popularity rose after one appeared in the 2015 family film "Max," but it is important to remember these dogs require plenty of stimulation and exercise; otherwise, they may develop destructive and neurotic behaviors.

Akita's most recognizable features are their webbed toes and curly, plush tail. Originally known simply as snow country dogs, the breed hails from the mountainous region of Japan, where they were used to track and hunt wild boar, deer, elk, and bears. Author and activist Helen Keller is said to have brought the breed into the U.S. in 1937, and Akitas have since become known for their remarkable loyalty. Arguably, the most famous Akita in history is Hachikō, a dog who waited for its owner for more than nine years after his death.

32 / 41Answer: Mastiff
Mastiffs are descendants of ancient Molossers, which are said to have originated in Tibet or northern India, where they were used to guard flocks against predators. Mastiffs are considered one of the world's largest breeds, standing approximately 30 inches tall and weighing between 120 pounds and 230 pounds. A 343-pound mastiff named Zorba earned his status as the world's heaviest dog, according to the Guinness Book of World Records. Although their massive size makes them intimidating, these dogs are surprisingly patient and affectionate, just ask the kids in the 1993 movie "The Sandlot."

34 / 41Answer: Chihuahua
The chihuahua is much more than Taco Bell's former spokesdog. These small dogs have very big personalities and perhaps even bigger hearts. Chihuahuas develop exceptionally strong bonds with their owners. Standing between 5 and 8 inches tall and weighing at most 6 pounds, Chihuahuas are naive about their small stature and are considered to be one of the best watchdogs, thanks to their alertness and proclivity to bark at suspicious activity.

38 / 41Answer: Brittany
Brittanys get their name from the area where they were developed hundreds of years ago: the westernmost region of France. They are primarily bird dogs, hunting anything and everything covered in feathers. Brittanys tend to be hyperactive and are therefore best paired with owners who can match their boundless energy with plenty of physical stimulation. Their exceptional exuberance also makes them quality companions for children, albeit only those old enough not to get trampled by the dog during a burst of enthusiasm.
