It’s hard not to fall in love with flat-faced dog breeds, with their squished-in noses and, in many cases, adorably wrinkled mugs. There’s something about a shorter muzzle that can give a dog an air of importance and magnificence. In fact, many flat-faced breeds were bred to be companions for nobility.
Unfortunately, there are downsides to having a pushed-in face. These breeds can be prone to brachycephalic syndrome, a condition that makes breathing more difficult. Telltale signs include snoring and heavy breathing. In general, snub-nosed dogs can be more susceptible to heatstroke and a variety of breathing problems.
From the Bulldog to the Boxer, get to know 13 dog breeds with flat faces, and let us know which one is your favorite.
Brachycephalic Breeds

Boston Terrier
The
Boston Terrier has quite a distinctive look: a friendly face, square jawline
and upright ears. And, who could forget his dapper tuxedoed coat? It’s a good
thing he’s small — you might want to take this handsome pup with you everywhere
you go!

Boxer
You know the Boxer face: wrinkled and worried-looking.
He also has a noble head and distinctively square jawline. But, though he may look serious, the typical Boxer is usually a goofball and isn’t above
clowning around and having fun.

Brussels Griffon
It’s no surprise the Brussels Griffon made our list. He was developed by crossing English Toy Spaniels, Pugs and a type of small German terrier. Like many of the breeds in this gallery, the Brussels Griffon usually doesn’t realize how small he is and tends to rule his home with an iron paw.

Bulldog
Perhaps one of the most exaggerated examples of a flat-faced breed, the Bulldog’s telltale wrinkled mug, short muzzle, Churchillian jowls and distinctive underbite make her easy to recognize (and adore).

Bullmastiff
Another “Bull” dog breed, the Bullmastiff is a large breed who often has a mind of his own. Don’t be surprised to find this pup, who can weigh up to 130 pounds, leaning on your leg or sitting on your feet as he snores and snorts.

Chinese Shar-Pei
We can describe this flat-faced breed in one word: wrinkled! You may feel compelled to go up and hug every Shar-Pei you see, but the breed can be a bit standoffish and is generally wary around people she doesn’t know.

Dogue de Bordeaux
Recognized for his massive head and deep wrinkles, the Dogue de Bordeaux usually turns heads wherever he goes. Just remember: He usually snores… and drools.

English Toy Spaniel
Not sure how to tell the difference between the English Toy Spaniel and the more popular Cavalier King Charles Spaniel? Just look at his head. The English Toy Spaniel has a domed skull, pushed-in nose, large eyes and a regal expression.

French Bulldog
With his adorably wrinkled face, signature bat ears and bowlegged gait, it’s no wonder the French Bulldog is so popular with celebrities like Martha Stewart and Leonardo DiCaprio. Not to mention the many famous Frenchies on Instagram and Facebook. Just keep in mind that this brachycephalic breed doesn’t do so well in hot temperatures and can be prone to snoring!

Japanese Chin
If
you want a canine comedian, consider the often humorous Japanese Chin.
His unpredictable antics and mischievous nature are likely to keep you
entertained.

Pekingese
Don’t underestimate the Pekingese. His looks may remind you a little of Cartman from South Park, but he’s a generally confident, regal and dignified breed.

Karin Newstrom, Animal Photography
Pug
He may wear a worried expression, but the Pug is known for having a certain joie de vivre that’s infectious. We dare you not to smile when in the presence of this, well, pug-nosed breed. Just bear in mind that he tends to snore and snort, so you may want to invest in some earplugs.

Shih Tzu
Bred for companionship, most Shih Tzus are happiest when they’re snuggling in your arms. Just don’t fall too hard for her precious mug or you may find yourself giving in to her every demand.
