Canine ears are incredible listening devices that allow dogs to detect sounds across a wide frequency range. Dogs can hear ultrasound, which is sound with a frequency greater than what humans can hear. In this article, we will explore how dog ears work and what dogs are capable of hearing.
Signs and Symptoms of Dogs Hearing Ultrasound:
When dogs hear a sound that is outside of our hearing range, there are some signs to look out for. Dogs may become more alert, with their ears perked up and their head raised. They may also investigate the source of the sound by sniffing the air or turning their head. Some dogs may bark, growl, or exhibit signs of discomfort like whining or whimpering.
Body Language:
Watch your dog’s body language for signs that they have detected a sound outside your range of hearing. Signs include being alert, barking, head tilting, wagging tail, raised ears, head turning, back hair on edge, and ears rotating and tilting.
The Science of Dogs Hearing Ultrasound:
Dogs have the ability to maneuver their ears in different directions. They have 18 muscles in their ears compared to the 6 muscles in the human ear. Dogs developed the ability to hear high-frequency sounds to determine the source of those sounds. Through a process called binaural spectral-difference cueing, dogs can compare the frequency of a sound as it arrives in each ear to determine its source.
Training with Ultrasound: The Pros and Cons:
There are dog training devices that use ultrasonic sound, such as whistles and anti-bark collars. These emit sounds at frequencies that dogs can hear but humans cannot. However, the use of ultrasonic training devices is a topic of debate among dog owners and trainers. Positive reinforcement training is generally regarded as the most effective way to train a dog. There are concerns about the unknown effects of ultrasonic sounds on dogs and the potential for over-correction with automated devices. It is recommended to consult with a vet or dog trainer for the best training method for your dog.

Tips & Things to Know
1️⃣ Pay attention to your dog’s behavior and body language to determine if they have heard a sound outside of your hearing range. Look for signs such as alertness, perked up ears, head tilting, and investigating the source of the sound.
2️⃣ Dogs have the ability to hear high-frequency sounds, including ultrasound. They can detect sounds up to 50 kilohertz or even higher. This is an important evolutionary adaptation for hunting and locating the source of a sound.
3️⃣ While ultrasonic training devices are available for dog training, it is important to consider the potential drawbacks. Positive reinforcement training is generally recommended as the most effective and humane method. Using punishment or correction can lead to fear and anxiety in dogs. Additionally, automatic devices that emit ultrasonic sounds may over-correct your dog without you knowing, potentially causing distress. Consult with a vet or dog trainer for advice on the best training method for your dog.
Frequently Asked Questions, Answered ✅
1. Can dogs hear ultrasound?
– Yes, dogs are capable of hearing sounds up to 50 kilohertz and possibly even higher, including ultrasound.
2. How can you tell if your dog has heard a sound outside your hearing range?
– Signs to look for include a change in alertness, perked up and rotating ears, head tilting, and possibly investigating the source of the sound.
3. What makes a dog’s hearing different from humans?
– Dogs have 18 muscles in their ears, allowing them to tilt, rotate, and wiggle their ears in different directions to capture sounds. Dogs can also compare the frequency of a sound in each ear to determine the source.
4. Are ultrasonic training devices effective and safe for dogs?
– There is debate among dog owners and trainers about the use of ultrasonic training devices. While some users find them effective, there are concerns about animal welfare and the potential for fear and anxiety in dogs.
5. What is the recommended training method for dogs?
– Positive reinforcement training, which rewards desired behaviors and ignores unwanted behaviors, is generally regarded as the most effective and humane training method. It is recommended to consult with a vet or trusted dog trainer for guidance on the best approach.
