A dog’s nose is a pretty magical thing, featuring about 300 million olfactory receptors compared to our paltry six million. With a sense of smell that scientists have determined to be anywhere from 10,000 to 100,000 more acute than us humans (and 40 times more brain space devoted to analyzing the odors they encounter) it’s safe to say that all dogs are impressive when it comes to the power of their snouts. But some are even more impressive than others.
Scent hounds are a class of dog that primarily uses scent—and not sight—to navigate the world around them. They generally feature long ears that hang close to the ground to help “scoop up” scents as they go, plus short statures that ensure they’re always close to where the action is (or more specifically, where the odors are).
So who are the best of the best when it comes to putting their nose to work? Here are 10 of the most celebrate scent hound breeds.
Plastic food and water dishes harbor bacteria that can be harmful for your dog’s nose. Switch to ceramic, glass, or stainless steel to resolve issues like dryness, redness, and sores.

That wiener dog stature isn’t just for show. Despite their small size, Dachshunds are prized hunters who use their nose to track subtle scents both on the ground and in the air.

Another short breed with incredible scent capabilities, the Basset Hound has been bred for years to help on the hunting field, and has a natural ability to pick up on and track even the most subtle of smells.

With a name like the American Foxhound, it shouldn’t be a surprise that these dogs excel when it comes to their scent abilities. This breed absolutely loves to put their nose to work, and are one of the few scent hounds that heads out on their own to track while their humans stay in place.

Weight: 60 to 70 pounds
Physical Characteristics: Similar in appearance to a Beagle but with a tall and lean frame; tri-color coat, plus the long ears that are ubiquitous with scent hound dogs

Weight: Depends on specific breed, and may be anywhere from 40 pounds to 100+ pounds

We’d be remiss to leave the Bloodhound off of this list. Bloodhounds are the poster child of the scent hound breed, and one of the original tracking breeds. They’ve been bred to put their noses to work on the hunt since as early as 1000 A.D., and have a one-track mind that is loathe to give up on a scent once they’ve found it.
Height: 23 to 27 inches
Weight: 80 to 110 pounds
Physical Characteristics: Distinct physical traits like huge ears, loose skin, and notoriously wrinkly faces and necks; one of the most physically powerful of all of the scent hound breeds, with a long frame that allows them to cover lots of ground at once—even when standing in placeContinue to 9 of 10 below.

They may look more Shih Tzu than hound, but Petit Basset Griffon Vendeens are widely celebrated for their scent-tracking skills.

You might not know much about the Harrier, which is an English scent hound breed that hasn’t made much of an appearance in popular canine culture (the AKC ranks them a lowly 189 out of 195 breeds). But while they might fly under the radar, Harriers are no stranger to the hunt, with short legs and strong noses that can carefully follow any animal they set their snouts on.
Height: 19 to 21 inches
Weight: 45 to 60 pounds
Physical Characteristics: Look like large Beagles, but are smaller than the Foxhound who also has that claim to fame; plenty strong—the better for a long day on the hunt—and have low set ears and loose lips that are equally integral to their scent hounding abilities
Breeds to Avoid
All dogs have exceptional noses, but they’re not all worthy of serving as scent hounds. Some breeds that aren’t ideal if you’re looking for scent hound qualities are short-snouted breeds like English Bulldogs, French Bulldogs, and Boxers, as well as notably non-scent dogs like Greyhounds, Whippets, and Chinese Crested.
