How Loud Is a Dog Bark? Decibel Levels Explained

How Loud Can Dogs Really Bark?

The loudness of a dog bark varies enormously depending on the breed, size of the dog, and how agitated or excited it is. A small Chihuahua's yap might register around 60–70 dB at close range, while a large breed like a German Shepherd or Rottweiler can produce barks exceeding 100 dB. The Guinness World Record for the loudest bark belongs to a Golden Retriever named Charlie, who was measured at an astonishing 113.1 dB.

The average dog bark at a distance of about 5 feet measures between 80 and 90 dB. That's roughly equivalent to the noise of a food blender or a loud alarm clock. While a single bark at this level isn't harmful, sustained barking at close range over extended periods can cause hearing fatigue and irritation.

Distance has a dramatic effect on perceived volume. A bark that measures 90 dB at 5 feet drops to approximately 70 dB at 50 feet and around 50–55 dB at 200 feet. This is why a neighbor's barking dog might be annoying but isn't typically a hearing health concern at normal residential distances.

Decibel Levels by Breed Size

While individual dogs vary, breed size is the strongest predictor of bark volume:

• Toy breeds (Chihuahua, Pomeranian): 60–80 dB — high-pitched but relatively low volume
• Small breeds (Beagle, Dachshund): 75–90 dB — Beagles are surprisingly loud for their size
• Medium breeds (Border Collie, Bulldog): 80–95 dB — moderate volume with varying pitch
• Large breeds (German Shepherd, Lab): 85–100 dB — deep, powerful barks that carry far
• Giant breeds (Great Dane, Mastiff): 90–110 dB — the deepest and loudest barks

Interestingly, some breeds are known as "quiet" dogs not because they bark softly but because they bark infrequently. Basenjis, for example, don't bark in the traditional sense at all—they produce a unique yodeling sound called a "baroo" that typically measures 60–75 dB. Conversely, breeds like Beagles and Huskies are known for persistent, loud vocalizations that can reach 90–100 dB, especially their distinctive howling.

Can Dog Barking Damage Your Hearing?

For most dog owners, occasional barking poses no hearing risk. However, certain situations warrant attention. Dog groomers, kennel workers, and veterinary staff who are exposed to multiple dogs barking simultaneously in enclosed spaces can experience noise levels exceeding 100 dB. A kennel with several large dogs barking at once can easily reach 105–115 dB, a level that requires hearing protection under OSHA guidelines.

If you work in an environment with frequent dog barking, or if your own dog barks persistently at close range, consider using hearing protection during peak noise periods. Basic foam earplugs can reduce exposure by 20–30 dB, bringing even the loudest barking down to safe levels.

To accurately assess the noise level in a kennel or from your own dog, a sound level meter provides objective data that can also be useful for noise complaint documentation or workplace safety assessments.

Measure It Yourself

Want to know exactly how loud your dog barks? Use our free online decibel meter to capture the peak sound level of your dog's bark. Hold your phone at a consistent distance (5 feet works well for comparison) and watch for the peak reading. You can then compare the result to our decibel comparison chart to put your pup's volume in context.
