Dog Breeds with Prominent Noses


The Bloodhound is an iconic breed famous for its droopy skin, long ears, and, of course, its enormous nose. This breed possesses an exceptionally large and highly sensitive olfactory system, making them excellent scent trackers. Bloodhounds are often utilized in search and rescue operations, as their remarkable noses can pick up even the faintest of scents.


Boxers are known for their distinctive square-shaped heads and strong, muscular bodies. Along with their characteristic jowls and expressive eyes, Boxers also have a large nose that complements their facial features. Their snouts are not only aesthetically appealing but also contribute to their exceptional sense of smell.


The Bullmastiff, a loyal and protective breed, boasts a large, broad head with a well-defined muzzle. Their prominent nose not only adds to their imposing appearance but also enhances their olfactory capabilities. Bullmastiffs have an acute sense of smell, which historically aided them in tracking and guarding duties.

The Function of Big Noses in Dogs

Enhanced Sense of Smell

The size of a dog’s nose is directly related to its olfactory capabilities. A big nose allows for a larger surface area inside the nasal cavity, accommodating more scent receptors. This increased receptor count enables dogs to detect and analyze a wide range of smells with greater precision and sensitivity. Dogs with big noses are often employed in scent-related jobs, such as search and rescue, narcotics detection, and tracking.

Cooling Mechanism

In addition to their olfactory function, big noses also serve a practical purpose in regulating body temperature. Dogs do not have sweat glands like humans, so they rely on other methods to cool down. The large surface area of a big nose allows for efficient heat exchange, as the moist membranes inside the nose help cool the blood circulating through the nasal capillaries.

Dog Breeds with Elongated Snouts


The Greyhound is a breed known for its sleek and slender build, which includes a long, slender head and a narrow snout. This elongated nose contributes to the Greyhound’s exceptional speed, as it allows for efficient airflow during high-speed pursuits. The extended snout also aids in scent detection, making Greyhounds versatile athletes both on the track and in activities requiring scenting abilities.

Afghan Hound

The Afghan Hound is famous for its flowing, silky coat and elegant appearance. Along with its regal looks, this breed possesses a distinctive long, narrow nose. The elongated snout of the Afghan Hound aids in capturing scents, allowing them to track and locate prey effectively. It also adds to their overall grace and beauty.


Borzoi, also known as the Russian Wolfhound, is a breed characterized by its slender body, graceful movements, and elongated head. The Borzoi’s long, narrow nose plays a crucial role in scent detection, making them exceptional hunters. While their noses may not be as large as those of Bloodhounds or Boxers, the elongated snout of the Borzoi serves its purpose in capturing scents effectively.

The Health of Big Nose Dogs

Breathing Difficulties

Some dog breeds with big noses, such as Boxers and Bullmastiffs, may experience breathing difficulties due to their brachycephalic (short-faced) features. It is important to ensure proper care and management of these breeds, as their unique facial structures can make them prone to respiratory issues. Regular veterinary check-ups and maintaining a suitable environment are essential for their well-being.

Nose Care

Dogs with big noses may require additional care to keep their noses healthy. The extended surface area of their snouts is susceptible to dryness, cracking, or sunburn. Applying a dog-safe nose balm or moisturizer can help protect and nourish their noses. It is also advisable to keep them away from extreme temperatures and provide shade during sunny days to prevent any discomfort or damage.
