Dogs have an impressive sense of hearing that allows them to detect sounds at frequencies much higher than humans can hear. Mice also make high-pitched squeaking noises as part of their communication. This article will explore the hearing range of dogs, the frequencies of mouse squeaks, whether there is overlap between the two, and dogs’ ability to detect the squeaks of mice in real-world settings. We will also touch on differences between dog breeds and other factors that influence dogs’ sensitivity to high-pitched sounds like mice squeaking.
Dog Hearing Range
Dogs have an incredible sense of hearing compared to humans. The hearing range of dogs in terms of frequency is approximately 40 Hz to 60,000 Hz, according to this source. This range is much wider than the average human hearing range, which is around 20 Hz to 20,000 Hz. In other words, dogs can hear both lower and higher pitched sounds than humans can.
For example, dogs can detect sounds in the ultrasound range, which includes very high-pitched sounds above 20,000 Hz that are inaudible to the human ear. So while humans can’t hear a dog whistle that makes a sound at 23,000 Hz, dogs can easily detect this frequency. This wider range, particularly on the upper end, allows dogs to hear frequencies and noises that we simply cannot perceive.
The reason dogs evolved such acute hearing across a large frequency range is likely linked to their ancestry as hunters. Being able to pick up subtle sounds and noises, including high frequencies made by potential prey, gave dogs an evolutionary advantage for tracking, hunting, and survival.
Mouse Squeaking Frequency
Mice produce ultrasonic vocalizations that are often described as “squeaks” by humans. However, these squeaks occur at frequencies beyond the range of human hearing, which tops out at around 20,000 Hz (20 kHz).
According to research, the fundamental frequency of mouse squeaks is approximately 3,800 Hz or 3.8 kHz when the mouse is in distress, such as being held by the tail or after losing a conflict (Ruat, 2022).
In other situations, mice can vocalize at frequencies ranging from 30-110 kHz, with most energy concentrated around 50-80 kHz (Warren et al., 2020). The wide frequency range allows mice to modulate their vocalizations to convey different meanings.
So in summary, mouse squeaks cover a broad ultrasonic range from about 4-110 kHz, far above what humans can hear without special equipment. But this allows them to communicate in ways inaudible to many predators.
Overlap Between Ranges
Research indicates that the average hearing range for dogs is approximately 67 Hz to 45 kHz, with some breeds able to hear tones as high as 60 kHz (LSU). In comparison, mice vocalize in the frequency range of 1 kHz to 91 kHz, with dominant energy in ultrasonic frequencies above 20 kHz (Animals Mom). There is significant overlap between the typical vocalization frequencies of mice and the hearing capabilities of dogs.
Most dogs should be able to hear mouse squeaks and vocalizations within the range of 20-45 kHz, as this overlaps with the upper limits of canine hearing. Very high frequency squeaks at 60-90 kHz would likely be inaudible to the majority of dogs. However, some breeds with excellent high frequency hearing, such as the Poodle, may be able to detect these extremely high mouse squeaks as well (Wikipedia).
In summary, the high frequency vocalizations of mice are well within the audible range for most dogs’ hearing. This allows dogs to detect and hunt mice effectively. Only the highest frequency mouse squeaks and chatter may be inaudible to some dog breeds. But the substantial overlap confirms that dogs can readily hear mice squeaking under normal circumstances.
Dog’s Sensitivity to High Frequencies
Dogs have excellent hearing and are known for their sensitivity to high frequency sounds that humans can barely detect. According to research from the University of California Davis, dogs can hear frequencies up to 45-67 kHz, while humans can only hear up to 20 kHz [1]. This means dogs can hear sounds at much higher pitches.
In particular, dogs are very sensitive to the high-pitched squeaking sounds mice make. Mice vocalizations are often above 20 kHz, which falls squarely in the frequency range dogs can hear [2]. For example, the peak frequency of mouse courtship songs can range from 30-110 kHz. This high frequency squeaking is likely amplified for dogs.
Research shows some dog breeds like poodles have hearing sensitivity up to 67 kHz, allowing them to detect even the highest pitched mouse squeaks [3]. With their heightened ability to hear these high frequencies, dogs are able to easily pick up on mouse squeaking that humans can’t even perceive.
Real-World Observations
There are many anecdotal reports of dogs responding to the high-pitched squeaks of mice. Pet owners describe catching their dogs staring intently at walls or floors and whimpering or growling in response to sounds they themselves cannot hear. According to some, dogs will scratch, dig, and sniff around areas where they detect mouse squeaks in an effort to locate the source of the sounds [1].
Some owners report their dogs reacting strongly at night when mice are most active. The dogs may whine, pace, or even bark when hearing mice moving and vocalizing behind walls and under floors where humans cannot detect them [2]. These reactions indicate dogs are able to hear the ultrasonic frequencies of mouse squeaks and identify them as signs of prey they wish to locate and capture.
Other Factors
There are several other factors besides a dog’s hearing range that determine whether they can hear a mouse squeaking, such as:
- Distance – Even if a mouse squeak is within a dog’s hearing range, they still need to be close enough to detect it. Dogs may not hear mice that are far away or in another room.
- Environment – Background noise, echoes, and obstructions in the environment can make it harder for dogs to pick out faint mouse squeaks. Dogs are more likely to hear mice in quiet indoor spaces.
- Alertness – If a dog is asleep, distracted, or focused on something else, they may not notice mouse squeaks. An alert, attentive dog is more likely to pick up on faint sounds.
- Breed – Some breeds like terriers have been selectively bred to hunt rodents and may be more attuned to mouse sounds (according to [URL removed]).
So while many dogs can physically hear high-frequency mouse squeaks, their ability to detect them in real-world conditions depends on multiple factors.
Breed Differences
Dog breeds have varying sensitivities when it comes to hearing high-pitched sounds like mice squeaking. According to the American Kennel Club (AKC), breeds like the Siberian Husky and Alaskan Malamute are specifically adapted for ultra-sensitive high frequency hearing, allowing them to effectively hunt small rodents that emit ultrasonic squeaks. In contrast, breeds like Bulldogs and Beagles have a reduced high frequency hearing range compared to other breeds.
One study from Louisiana State University (LSU) tested the hearing ranges of various dog breeds using auditory evoked brainstem response. They found that the Poodle, Saint Bernard, and Chihuahua were able to detect tones up to 46 kHz, while the Basset Hound’s range only reached 41 kHz. So while most dogs can hear mice squeaking, some breeds are particularly attuned to these high-pitched sounds.
Conclusion
After analyzing dogs’ hearing range, mice squeaking frequencies, and the overlap between the two, we can conclude that yes, dogs are able to hear mice squeaking. While human hearing maxes out around 20 kHz, dogs can hear frequencies up to 45 kHz and even higher. Mice vocalizations are in the ultrasonic range, around 50 kHz or more. Though mice squeaks are at the upper threshold of dogs’ hearing, dogs do seem able to pick up these very high-pitched sounds. In real world observations, dogs often prick up their ears and become alert when they detect mouse sounds outside of human perception. Certain breeds like Terriers seem particularly attuned to picking up rodent noises. So in summary, the overlap between dogs’ excellent high frequency hearing and mice’s ultrasonic vocalizations means that dogs can indeed hear when mice are squeaking, letting them locate and hunt these small rodents.
