Dogs possess a remarkable sense of hearing, capable of registering sounds well beyond the range of human ears. While it’s not about specific words, dogs can detect noises at frequencies of 40 to 46,000 hertz, compared to humans who can only hear up to 20,000 hertz. This allows dogs to perceive a much broader spectrum of sounds, including ultrasonic frequencies that are inaudible to us.
What Frequencies Can Dogs Hear?
Dogs have a wider hearing range than humans. They can register sounds between 40 hertz and 46,000 hertz. Humans, in comparison, can only hear frequencies from 20 hertz to 20,000 hertz. This broader range enables dogs to detect high-pitched sounds that humans simply cannot perceive.[1][2][3]
How Does a Dog’s Hearing Compare to Other Animals?
The following table illustrates the hearing ranges of humans and other animals:
| Animal | Low (Hertz) | High (Hertz) |
|---|---|---|
| Humans | 20 | 20,000 |
| Cats | 100 | 32,000 |
| Dogs | 40 | 46,000 |
| Horses | 31 | 40,000 |
| Elephants | 16 | 12,000 |
| Cattle | 16 | 40,000 |
| Bats | 1,000 | 150,000 |
| Grasshoppers and Locusts | 100 | 50,000 |
| Rodents | 1,000 | 100,000 |
| Whales and Dolphins | 70 | 150,000 |
| Seals and Sea Lions | 200 | 55,000 |
Why Do Dogs Have Such Sensitive Hearing?
Aboriginal breeds of dogs developed large, erect, and mobile ears, enabling them to hear sounds from great distances in any direction. Modern breeds have retained this acute sense of hearing, with some breeds exhibiting better hearing capabilities than others. Additionally, dogs possess the ability to selectively shut off their inner ear to filter out distracting noises, further enhancing their auditory focus.[3]
How Does a Dog’s Hearing Affect Its Behavior?
A dog’s acute hearing plays a crucial role in various aspects of its behavior. Their hearing allows them to detect potential threats from afar, assist in hunting, and communicate with other dogs. Moreover, their sensitivity to sound makes them valuable in tasks such as search and rescue operations, where they can detect faint sounds that humans might miss.[3]

Can dogs hear ultrasonic sounds?
Yes, dogs can hear ultrasonic sounds. Their hearing range extends up to 46,000 hertz, which is well beyond the human hearing limit of 20,000 hertz. This ability allows dogs to perceive high-frequency sounds that are inaudible to humans, such as those emitted by rodents or specialized dog whistles.[1][3]
Do certain dog breeds have better hearing than others?
Yes, certain dog breeds have better hearing than others. Aboriginal breeds, for instance, have large, erect, and mobile ears that enhance their ability to detect sounds from great distances. While modern breeds have generally retained this acute sense of hearing, there can be variations in hearing capabilities among different breeds.[3]
How can I protect my dog’s hearing?
Protecting your dog’s hearing involves several measures. Avoid exposing your dog to excessively loud noises, such as fireworks or concerts, as these can cause hearing damage. When necessary, use ear protection designed for dogs in noisy environments. Regular checkups with a veterinarian can also help detect and address any potential hearing issues early on.[3]
In summary, while dogs don’t necessarily hear certain words better than others, their exceptional hearing range allows them to perceive a wider spectrum of sounds compared to humans. This heightened auditory perception plays a vital role in their behavior, communication, and ability to perform various tasks.
