Introduction
Have you ever been startled awake by a small dog’s shrill barks in the middle of the night? Or felt the walls shake when your neighbor’s massive Great Dane lets out a volley of deep, booming barks? Most dog owners have an intuitive sense that little dogs tend to bark more loudly and frequently than their larger counterparts. But is this perception accurate, or is it a myth that tiny pups have more “bite” in their bark? This question has sparked many lively debates among canine enthusiasts. Let’s dig into the factors that influence bark loudness to find out if those petite pooches really do make more noise!
Typical Noise Levels of Dog Barks
The loudness of a dog’s bark is commonly measured in decibels (dB). Decibels are a logarithmic unit used to express the intensity of sound. Studies have found that the average noise level of a dog bark ranges from 60 to 110 dB, depending on the size and breed of the dog (Source).
In general, small dogs with shorter vocal tracts produce higher-pitched barks that are not as loud. Small dogs typically bark at 60-70 dB, which is about as loud as normal human conversation (Source). Medium-sized dogs often bark at 70-90 dB, similar to the noise level of a passing car. Large dogs with longer vocal cords and resonating chambers tend to produce louder, lower-pitched barks reaching 90-110 dB, comparable to the volume of a motorcycle or small aircraft.
While these decibel ranges are typical, the actual bark loudness depends on other factors like the dog’s vocal effort and health. But in general, physics indicates that larger dogs with more capacious vocal tracts will produce louder barks than smaller dogs.
Other Factors that Influence Bark Volume
While size is not the only factor, research shows that larger dogs tend to have louder barks than smaller dogs. However, there are other aspects that can also affect the volume of a dog’s bark.
One major factor is the dog’s breed. Certain breeds like hounds and terriers have been selectively bred to produce loud, far-reaching barks for hunting or guarding purposes. Breeds like the Beagle and Foxhound are known for their boisterous baying, while Miniature Schnauzers and West Highland White Terriers have shrill, high-pitched barks. In contrast, breeds like Basenjis and Shiba Inus are relatively quiet. So a Beagle’s bark can be much louder than a Shiba Inu’s, even if they are the same size.
A dog’s training and conditioning can also influence bark volume. Dogs that are reinforced for barking loudly may increase their bark intensity over time. Dogs that are punished for excessive barking may learn to tone it down. And dogs that are never trained may default to whatever feels natural for their breed. Proper training can help teach a naturally loud dog to use an indoor or alert bark as needed.
Finally, a dog’s environment impacts their motivation to bark. Dogs left alone frequently or living near visual triggers like fences may bark more persistently. Providing enrichment, exercise, and access to people and dogs can reduce boredom-related barking. But external factors like squirrels, cars, and passersby can also incite excited barking episodes.
Anatomy and Physics of Barking
The production of a dog’s bark relies on the passage of air through the larynx (voice box) at high pressure, causing the vocal cords within the larynx to vibrate and produce sound waves. As explained in an article on wired.com, “Molnar’s statistical algorithm showed that dog barks displayed common patterns of acoustic structure. In terms of pitch and repetition…” (Source).
The larynx contains cartilage structures like the thyroid, cricoid, and arytenoid cartilages which protect the vocal folds and control their position and tension. Larger dogs generally have larger larynxes and vocal tracts. Physics dictates that a larger sound chamber can resonate at a lower frequency and produce louder volumes. As stated on animalhackers.com, “Barking is produced when air passes at high pressure through the larynx, causing the vocal cords to vibrate. The larynx comprises cartilages (thyroid, cricoid and arytenoid) that protect the vocal folds and control their position and tension” (Source).
Therefore, the basic physics of sound production suggest that bigger dogs with larger larynxes and vocal tracts can potentially produce louder barks than smaller dogs, all else being equal.
Scientific Research on Bark Loudness
There have been a few scientific studies that have examined the relationship between dog size and bark loudness. One study published in 2013 by researchers at the University of Arizona analyzed barks from different sized dogs and measured their pitch and volume [1]. They found that larger dogs tend to bark at a lower pitch than smaller dogs. This is likely due to their longer vocal tracts and vocal folds. However, they did not find a significant difference in bark volume between large and small dogs.
Another study in 2017 analyzed barks from over 2,000 dogs of various breeds [2]. They measured the fundamental frequency, which relates to pitch, and found that larger breeds like Great Danes and St. Bernards barked at lower frequencies than smaller breeds like Chihuahuas and Pomeranians. Again, there was no major difference found in overall bark volume between size categories.
While the pitch of barks varies by size, there is little concrete scientific evidence showing that larger dogs objectively bark louder than smaller dogs when factors like the individual dog and situation are controlled for.
Owner Perceptions of Bark Loudness
Many dog owners seem to perceive larger dogs as having louder barks compared to smaller dogs. However, anecdotal evidence suggests this perception may be skewed by other factors. Some reasons owners may perceive larger dogs as louder include:
– The deep, booming quality of large dogs’ barks simply sounds bigger to our ears, even at the same decibel level as a small dog. Their larger vocal cords and anatomy produce a fuller sound (1).
– We associate larger size with greater volume capacity, assuming big dogs must be capable of greater loudness. But this does not necessarily equate to habitually louder barking (2).
– Large dogs’ barks are more difficult to ignore due to their deep pitch, so they seem more bothersome. Small dogs’ high-pitched yaps blend into background noise more easily (3).
– Large dogs tend to guard territory more aggressively. Their barks often carry a sense of urgency that makes them seem louder. Small dogs bark more frequently from non-threatening excitement.

Practical Implications of Bark Volume
The loudness of a dog’s bark can have practical implications for owners, especially when it comes to potential noise complaints from neighbors. As the ASPCA notes, “Excessive and uncontrolled barking can be annoying and upsetting for your neighbors.”
According to the AKC, persistent and loud barking is one of the most common reasons dogs are relinquished to shelters. Noise complaints are often cited in legal disputes between neighbors over barking dogs.
To mitigate noise complaints, the AKC recommends training techniques like desensitization and positive reinforcement to curb excessive vocalization. Teaching a “quiet” command can also help owners get better control over their dog’s barking.
For training, breed traits should be considered. Herding and hunting dogs tend to be more vocal and may require more diligent training. Meanwhile, breeds like Basenjis and Beagles have a tendency to howl rather than bark.
The age of the dog is another factor. Puppy barking often naturally lessens as a dog matures. Older dogs may experience cognitive decline or develop separation anxiety leading to increased barking. Consulting a veterinarian can help determine if medical issues are contributing.
While large dogs may have louder barks, they are not inherently more prone to nuisance barking. With proper training and care, dogs of any size can learn appropriate barking behavior and be good neighbors.
Recommendations for Mitigating Nuisance Barking
There are several tactics dog owners can try to reduce excessive or unwanted barking:
Exercise – Ensuring your dog gets adequate physical and mental stimulation through walks, play time, and training can reduce boredom barking. A tired dog is less likely to bark excessively (AKC).
Remove triggers – Identify what triggers your dog’s barking and remove those triggers if possible. For example, keeping curtains closed to block views that get your dog riled up.
Training – Teaching your dog the “quiet” command helps give them an alternative behavior and allows you to interrupt barking. Always reward quiet behavior with treats and praise.
Distractions – When barking occurs, interrupt the behavior by engaging their attention with toys or activities like obedience training. This refocuses them into calmer behaviors.
Discourage demand barking – Ignore attention-seeking barking and reward your dog with attention only when they are quiet. This prevents reinforcing the barking.
Desensitization – Gradually expose your dog to triggers in a controlled manner, rewarding calm behavior. This helps recondition their response to stimuli that induces barking.
Consult an expert – If your efforts don’t work, seeking guidance from veterinarians, certified dog trainers, or behaviorists can provide helpful individualized solutions.
Conclusions
In summary, research suggests that there is no consistent correlation between a dog’s size and the volume of its bark. While larger dogs like St. Bernards tend to have deeper, louder barks than small dogs like Chihuahuas, many medium and small dogs can bark just as loudly as larger breeds. Factors like genetics, throat anatomy, temperament, and training have more impact on bark volume than size alone.
The main takeaway is that nuisance barking has more to do with the way a dog is conditioned than its physical stature. Responsible pet owners should train their dogs not to bark excessively or at inappropriate times, regardless of the breed. Consulting a veterinarian and animal behavioralist can help mitigate nuisance barking that disturbs neighbors and others in the community.
