Drool is just something dog owners have to deal with, but some deal with a lot more than others. Certain dog breeds slobber more than their counterparts — and boy, can some of them produce a lot! If you don’t want your furniture covered in slime, perhaps steer clear of dog breeds that drool the most.

But First… Why Do Some Dogs Drool More?

Dogs that drool a lot typically have loose skin around their mouths. Most of the drooliest dog breeds have big, droopy jowls, meaning that the skin hangs down more along the sides of their mouths and jaws. This loose skin makes it harder for dogs to keep saliva in their mouths, resulting in drool. This can become even more prevalent when exercising or after eating or drinking.

Despite the mess, drooling isn’t all bad! Along with panting, slobber also helps dogs cool down. When excess salivation is combined with open-mouth breathing, drooling ensues. Drool also helps lubricate the mouth, which helps prevent the development of oral health problems.

While there are benefits of drool, it may be harder to appreciate them when there’s slobber all over your home. If you’re looking for a clean dog, beware! These are the 11 dog breeds that drool the most.

11. English Bulldog

The flat-faced English bulldog is a notorious drooler. Brachycephalic breeds have squished, wrinkly faces without a pronounced snout. This results in bigger, looser jowls, which makes it hard for them to keep their spit in their mouths. Another side effect of their flat faces is that they often mouth breathe, which can cause saliva to slip out of their open mouths.

Taking in that much air has other repercussions as well. Bulldogs are notorious for snoring and excessive flatulence. So, if you’re looking for a dog that is quiet and clean (and not smelly), this probably isn’t the breed for you.

10. Basset Hound

Basset hounds are known for their floppy ears and even droopier jowls, so it’s no surprise that they ended up on the list of dog breeds that drool the most. Equipped with a great sense of smell, basset hounds have sensitive salivary glands. The more they smell, the more saliva they produce — and sometimes it’s too much to stay in their mouths.

In addition to having a lot of saliva, basset hounds also have more bone per pound than any other dog breed. Essentially, in proportion to their short stature, the basset hound has the heaviest bones. Despite only measuring around 15 inches high, they can weigh up to 70 pounds.

9. Boxer

Next on our list of dog breeds that drool the most is the boxer. Boxers are another brachycephalic breed that makes up for their lack of snout with a ton of drool. Highly active dogs, they love physical activity, excel in dog shows, and can run 38-45 miles per hour. However, this high energy has a downside. Exercise often triggers even more saliva production in these dogs, resulting in additional slobber. Still, if you’re looking for a running buddy or a playmate for a child, boxers are a great choice.

8. Newfoundland

Newfoundlands have thick, double coats that make them great swimmers, even in cold water.


Has anyone invented a doggie bib? The Newfoundland could definitely use it. The Newfie is a gentle giant that produces a gigantic amount of drool. As a bonus, the Newfoundland’s long, thick coat often catches drool and becomes saturated. Owners of these dogs spend a lot of time wiping drool off their dog’s face (as well as wiping down any surface the Newfie is around!). It’s not rare to see a Newfoundland with ropes of drooling hanging from its mouth.

While they may be perpetually soggy, Newfoundlands don’t mind. Newfies love water and are incredibly good swimmers and make great water rescue dogs, thanks to their impressive strength, muscular build, and webbed feet.

7. Great Dane

The Great Dane is another dog that is great at saliva production. Loose jowls make this big dog a veritable drool machine. And these dogs are big. According to the Guinness Book of World Records, the world’s tallest dog was a Great Dane named Zeus, who was 44 inches tall and stood 7 feet, 4 inches on his hind legs. This height advantage means that when a Great Dane shakes its head, you’re likely to end up with drool on your ceiling.

6. Bloodhound

Bloodhounds have excellent noses and are often used for tracking.


If you want to talk about dog breeds that drool the most, let’s talk about the bloodhound. Like the basset hound, bloodhounds have an excellent sense of smell. Thanks to their 230 million olfactory cells, their sense of smell is 1,000 times better than a human’s. A bloodhound’s drool actually helps enhance the scents they pick up as saliva collects in the folds of their mouths. This allows bloodhounds to follow a scent trail for more than 130 miles that is up to 300 hours old, making them remarkable trackers.

5. English Mastiff

The world’s heaviest dog was an English mastiff named Zorba who weighed 357.1 pounds. While not all mastiffs rival Zorba in weight, don’t expect them to be small. The average weight for a mastiff is between 120-230 pounds.

While we can’t say how much the saliva produced by these dogs weighs, we can confidently say that it is a lot. The mastiff’s big jowls and loose lips collect drool that they will happily shake all over your home. If you’re going to share your house with a mastiff, you may want to stash towels in every room for prompt drool cleanup.

4. Bernese Mountain Dog

Another long-hair breed that drools, the Bernese mountain dog often has jowls soggy from slobber. And they want you to get up close and personal with all that drool: Bernese mountain dogs are incredibly affectionate and fond of cuddling. If you want a 100-pound dog coated in spit in your lap, this is the perfect breed for you. They also love kids, and will happily contribute their drool to the messes made by children.

3. Dogue de Bordeaux

While smaller than some other mastiff breeds, male Dogue de Bordeaux can weigh over 100 pounds.


The Dogue de Bordeaux is also known as the French mastiff. Like its English counterpart, this mastiff is a prolific drooler and deserves a top spot on the list of dog breeds that drool the most. While they have powerful, highly muscled bodies, they have loose jowls that taper downward, allowing drool to collect at the bottom.

First recognized as a breed by the American Kennel Club (AKC) in 2008, the Dogue de Bordeaux became well known to the public in the late 1980s, when one named Beasley starred alongside Tom Hanks as Hooch in the 1989 masterpiece “Turner & Hooch.”

2. Cane Corso

are incredibly loyal dogs that can be very protective.


The intelligent Cane Corso is yet another mastiff breed to make the top droolers list. Known for their impressive size, these dogs are often used as guard dogs due to their protective nature and loyalty.  Also called the Italian mastiff, this breed loves stimulation and having tasks to complete. As a result, they are great at scent work, tracking, and agility.

Perhaps the drooliest of all droolers is the Saint Bernard. Prepare for drool to go flying when these big dogs shake their enormous heads; their large jowls collect a ton of it. Popularized by the 1992 comedy “Beethoven,” the Saint Bernard is a large working dog originally bred for rescue work in the Alps. While their Alpine search-and-rescue duties ended in 1955, the dogs are now primarily used for companionship, as their gentle, calm nature makes them an excellent family pet.
