A dog’s nose is a pretty magical thing, featuring about 300 million olfactory receptors compared to humans’ paltry 6 million. Scientists have determined their sense of smell to be anywhere from 10,000 to 100,000 times more acute than humans. Plus, dogs have 40 times more brain space devoted to analyzing the odors they encounter. All dogs are impressive when it comes to the power of their snouts, but some are even more impressive than others.

Here are 10 of the most celebrated scent hound breeds.

Breed Characteristics

Scent hounds primarily use scent—and not sight—to navigate the world around them. They generally have long ears that hang close to the ground to help “scoop up” scents as they go and short statures that ensure they’re always closer to where the odors are. Many of these dogs are used for hunting; working in search, rescue, and recovery; and serving as specialized sniffer dogs.

Tip

Plastic food and water dishes harbor bacteria that can be harmful to your dog’s nose. Switch to ceramic, glass, or stainless steel to resolve issues like dryness, redness, and sores.

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 (but instead, sighthounds) like greyhounds, whippets, and Afghan hounds.
