Our dogs have an impressive sense of hearing, with ears more powerful than ours. They can pick up sounds at a distance four times greater than humans and detect sounds across a wider frequency range. Dogs can hear sounds from 40 to 60,000 Hz, while humans can only hear sounds from 20 to 20,000 Hz. This means dogs can detect a wide range of noises that we may not even notice.
Signs Your Dog Has Heard Something
It can be surprising when your dog hears something that you haven’t noticed. Your dog may suddenly become alert and investigate an interesting or concerning noise while you remain oblivious. To recognize when this happens, look for signs that your dog has heard something you haven’t.
One way to do this is to watch your dog’s ears. Dogs have 18 muscles in their ears, allowing them to rotate and move them in different directions to capture sounds. When they hear an interesting sound, you’ll notice their ears move up, down, back, and to the side.
Depending on the sound, your dog’s reaction may vary. They may dismiss some noises with a raised eyebrow and a sigh, while others may require an immediate response and investigation. Your dog’s body language can change from relaxed to alert and tense. Their ears will perk up, they’ll raise their head, and they may even get up to explore the source of the sound. Some dogs may bark, growl, whine, whimper, raise their hackles, or wag their tail, depending on how they perceive the sound.
Body Language
Pay attention to your dog’s body language to determine if they’ve heard something you haven’t. Signs to look for include growling, being alert, barking, head tilting, tail wagging, and raised ears. Other signs may include rotating and tilting ears, head turning, and moving to investigate the source of the sound.
The Science of a Dog’s Hearing Range
While dogs are known for their sense of smell, their hearing ability is equally impressive. Humans can detect sounds from 20 to 20,000 Hz, but dogs can hear sounds as high as 60,000 Hz. This ability evolved from their wolf ancestors, who relied on their hearing to hunt and detect danger.
Dogs can locate where a sound is coming from through a process called binaural spectral-difference cueing. When a dog hears a sound, the ear farthest from the source is shadowed by the head, absorbing some frequencies. By comparing the frequency range captured in each ear, dogs can determine the source of the sound.
Training Using Ultrasonic Sound
Some pet products aim to utilize a dog’s high-frequency hearing ability. Training whistles and anti-bark collars emit sounds above the human hearing range to correct behaviors. However, there is debate over the safety and effectiveness of these devices.
Positive reinforcement training using rewards is recommended by experts. Punishment or correction-based methods may cause fear and anxiety in dogs. Determining the level of discomfort caused by ultrasonic devices is difficult since humans cannot hear the sound. It is best to consult a force-free dog trainer for guidance on positive reinforcement training.

Tips & Things to Know
1️⃣ Pay attention to your dog’s ear movements and body language to determine if they have heard something that you may have missed. Dogs have a greater range of hearing than humans, so they may pick up on sounds that are outside of our hearing range.
2️⃣ Watch for signs such as raised ears, head tilting, and increased alertness that indicate your dog has detected an interesting or concerning sound. Depending on the sound, your dog’s reaction may vary, so it’s important to be aware of their body language and behavior.
3️⃣ When training your dog, consider using positive reinforcement methods instead of devices that emit ultrasonic sounds. There is debate about the safety and effectiveness of such devices, and positive reinforcement training is generally considered the best approach to help your dog learn desired behaviors without causing fear or anxiety. If you need guidance, contact a force-free dog trainer for assistance.
Frequently Asked Questions, Answered ✅
1. What is the hearing range of dogs compared to humans?
– The hearing range of dogs is approximately 40 to 60,000 Hz, while humans can only hear sounds from 20 to 20,000 Hz.
2. How can you tell if your dog has heard something you haven’t?
– Watch your dog’s ears and body language. Their ears may move and rotate, and their body may become alert and tense. They may also bark, growl, wag their tail, or raise their hackles.
3. How do dogs locate where a sound is coming from?
– Dogs use a process called binaural spectral-difference cueing. The ear farthest away from the source of the noise is shadowed by the head, allowing the dog to compare the frequency range of the sound captured in each ear to determine its location.
4. Are ultrasonic dog training whistles and anti-bark collars safe to use?
– There is debate among dog lovers. Some recommend their use, while others claim they are inhumane and can cause fear and anxiety in dogs. Positive reinforcement training using rewards is generally recommended by experts.
5. What training method is recommended for dogs?
– Positive reinforcement training using a rewards-based method is recommended. If unsure, it is advised to consult a force-free dog trainer.
