15 Scientific Facts About A Dog’s Ears And Hearing Abilities

If your dog could speak, they’d probably tell you how much they rely on their ears to understand the world around them. They can pick up sounds we can’t even detect and use their ears in ways no human can. If you’re curious, here are some interesting facts about your dog’s ears and hearing powers.

Dogs Can Hear Very High-Pitched Sounds

They are masters at hearing high-pitched noises (ultrasounds) that are completely out of our range. While humans hear up to 20 kHz, dogs can pick up sounds up to 60 kHz. That’s why they can hear things like dog whistles and some insect sounds, which are silent to us.

Even The Faintest Sounds Can Be Tracked

If a sound is faint, your dog won’t miss it. Their hearing is so sharp that they can detect even the smallest sounds with volumes as low as -5 dB and -15 dB on average. This includes the rustling of leaves or the hum of a device’s frequency that we can’t hear.

Sounds From Afar Are Also In Range

Dogs’ hearing is super sensitive. It allows them to detect sounds from up to 100 yards away. As we struggle to hear noises from the next room, dogs can catch sounds from a neighbor’s home. It keeps them alert and mindful of their environment.

Dogs Have A Lot Of Ear Muscles

Those cute little ears have around 18 muscles controlling each ear. These muscles give them the ability to move and rotate their ears in all directions. Due to this ability, they can even pinpoint exactly where a sound is coming from, just like a radar system.

Their Ears Can Rotate 180 Degrees

Dogs can rotate their ears up to 180 degrees, allowing them to hear sounds from any direction. Whether it’s a noise behind them or something from the side, they’re always on top of it. Imagine being able to move your ears like your dog does.

Dogs’ Ears Can Move Independently

They can move each ear independently. One ear can be pointed forward, while the other may rotate backward to listen to something else. This helps them detect noises from every angle at the same time and stay aware of their surroundings.

They Can Tune Out Unnecessary Sounds

Dogs have a remarkable ability to focus and filter out background noise. They can ignore the hum of a fan or the buzz of a light bulb to concentrate only on the sounds that matter. This skill helps them do things like listen to their owner’s voice or hear an approaching vehicle.

Puppies Are Born Deaf

It’s hard to believe, but puppies are born completely deaf. They rely on their sense of touch and smell in the early days. By the time they’re around two weeks old, their hearing starts to develop and opens up a whole new world of sound for them to explore.

Similar Sounds Can Confuse Them

When two sounds are too similar in frequency or tone, it can throw them off. For example, it’s possible that a high-pitched dog whistle might sound the same as the beep of a microwave to dogs. So sometimes, it’s hard for them to understand the difference.

They Use Ears To Express Emotions

Just like humans use facial expressions, dogs use their ears to show how they’re feeling. When your dog is excited, their ears will perk up. If they’re scared or anxious, their ears will flatten. Pay attention to your dog’s ear movements, as it can tell you a lot about their mood.

Dogs Process Their Owners’ Vocal Tones

It’s not just the words you say. Dogs are highly tuned into the tone of your voice. Whether you’re angry, happy, or calm, your dog’s ears can pick up on the subtle changes in your tone. That’s why they respond so well to upbeat, positive voices but often shy away from harsh ones.

Their Hearing Power Can Decrease With Age

Just like humans, dogs experience changes in their hearing as they get older. Senior dogs often lose some of their sharpness when it comes to high-pitched sounds. So, they can miss out on some calls and sounds they used to catch when they were younger.

Their Ears Are Sensitive To Touch

Dogs’ ears are packed with nerve endings that make them extra responsive. Your light finger movements create a soothing sensation for them. That’s why many dogs love a good ear scratch, as it stimulates the nerves, making them feel great.

Dog Ears Emit Pheromones

Did you know your dog’s ears can release pheromones? These chemical signals let them talk to other dogs. When dogs shake their ears or flick them, they are spreading these scent markers to signal emotions or intentions. It helps them connect with other dogs.

Some Breeds Have Even Sharper Hearing

Do you know why certain breeds like German Shepherds and Basset Hounds are particularly helpful with police work? That’s because their ears (and nose) are sharper than many other breeds. So, you’ll often see them helping with tough tasks like search-and-rescue.
