Ultrasonic training devices for dogs are becoming increasingly popular and can be easily purchased online. These devices emit a high-frequency sound that humans cannot hear, but dogs can. While some dogs may not be affected by these sounds, others may exhibit signs of distress and nervousness. There is also a risk of lasting psychological harm to dogs, and negative reinforcement training is generally considered less effective than positive reinforcement. Therefore, it is important to carefully consider the potential risks and ineffectiveness of using ultrasonic sounds for dog training.

What You'll Learn

Ultrasonic pest repellents can distress dogs
Ultrasonic pest repellents are devices that emit sound waves at high-frequency pitches to deter pests such as rodents and insects. These frequencies are typically beyond the range of human hearing, but dogs have a much wider range of hearing and can detect sounds at much higher frequencies.
While some dogs may not be bothered by these sounds, others may show signs of distress. Some common indicators that your dog is distressed by ultrasonic pest repellents include nervous behaviour, confusion, or aggression. Dogs that are distressed by these sounds may also exhibit body language cues such as turning and running in the other direction, backing away, or tail tucking.
If your dog is distressed by ultrasonic pest repellents, there are several alternatives you can consider. You can try natural repellents such as essential oils, humane traps, or physical barriers. You can also consult your vet for advice on pet-safe pest control methods.
It is important to monitor your dog's behaviour when first introducing an ultrasonic pest repellent to ensure they are not negatively affected. If you notice any signs of distress, it is recommended to adjust the placement or settings of the device or consider alternative pest control methods.

Ultrasonic training devices: positive punishment or negative reinforcement
Ultrasonic training devices emit a high-frequency sound that can be heard by dogs but remains inaudible to humans. They are marketed as a safe and humane alternative to electronic shock collars, which are widely considered cruel. However, the use of ultrasonic devices for dog training is controversial and has sparked debates about their potential negative impact on dogs' well-being.
Ultrasonic training devices fall under the category of "aversives," as they impose an unpleasant sensory experience on dogs. This places them squarely in the realm of "positive punishment," which involves using discomfort to encourage a particular behaviour. The use of aversive techniques has been linked to lasting psychological harm in dogs and is generally considered less effective than positive reinforcement techniques.
Positive reinforcement, such as food rewards, play, praise, and affection, has gained favour among dog trainers as a more effective and humane approach. This method incentivizes desirable behaviour without causing discomfort or distress. It addresses the underlying causes of unwanted behaviour, such as frustration or lack of stimulation, and strengthens the bond between the dog and its owner.
When used correctly and responsibly, proponents of ultrasonic devices argue that they can effectively curb unwanted barking. They emphasize the importance of pairing ultrasonic devices with positive reinforcement to create positive associations and redirect the dog's behaviour. However, critics argue that these devices are still punishment-based, aiming to stop a behaviour rather than increase it, which is the essence of negative reinforcement.
The distinction between positive punishment and negative reinforcement is crucial. While both involve aversive stimuli, the goal of positive punishment is to stop an undesirable behaviour, whereas negative reinforcement seeks to increase the likelihood of a desired behaviour by removing something aversive. In the context of ultrasonic devices, the intention is to stop barking or other unwanted behaviours, making them instruments of positive punishment rather than negative reinforcement.

Dogs' sensitive hearing means they can hear ultrasonic frequencies
Dogs have a far more advanced sense of hearing than humans. Their sense of hearing is about four times better than a human's, allowing them to hear noises that humans cannot. This is because dogs can hear at a much higher frequency than humans. While humans can typically hear frequencies up to 20,000 Hz, dogs can hear sounds as high as 45,000 to 65,000 Hz. This means that dogs can hear ultrasonic frequencies, which are sounds with frequencies above the range of normal sounds.
The fact that dogs can hear ultrasonic frequencies has been known since the invention of the Galton whistle by Sir Francis Galton in the late 19th century. The whistle emits ultrasonic sounds beyond the upper limit of human hearing, and Galton observed that dogs could detect these sounds.
Today, ultrasonic devices are commonly used as pest control and dog training tools. Pest control devices emit ultrasonic sounds to frighten off pests, and it is likely that dogs can hear these sounds. Dog training devices, such as ultrasonic collars and fences, emit a high-pitched sound to deter unwanted behaviour.
There are concerns about the welfare implications of using ultrasonic devices on dogs. A study published in 1990 confirmed that ultrasonic sounds were aversive to dogs, and there is evidence that aversive training techniques can cause lasting psychological harm. Animal welfare advocates have also raised concerns about the misuse of ultrasonic devices, particularly when used at excessive volumes or frequencies that may cause distress or confusion in dogs.
Some signs that a dog has heard an ultrasonic sound include looking around in a confused manner, head tilting, running towards the source of the sound, whining, backing away, and barking. If a dog appears nervous or distressed by an ultrasonic noise, it is recommended to monitor its reactions and consider alternative pest control methods.

RSPCA Australia's stance on ultrasonic collars
RSPCA Australia has taken a firm stance against the use of ultrasonic collars, which are dog collars that emit a high-pitched sound to deter barking. The RSPCA is opposed to any electronically activated devices that deliver electric shocks or other aversive stimuli, such as high-pitched sounds or citronella spray. They consider these devices to inflict pain, fear, and discomfort on animals and thus, classify them as a form of punishment.
Ultrasonic training devices have become increasingly popular and are easily available online. They are often marketed as a safe and humane alternative to electronic shock collars. However, there is a lack of evidence to confirm that ultrasonic collars are harmless. On the contrary, reports have been received of dogs exhibiting fearful, anxious, and distressed behaviour due to the high-pitched sounds emitted by these collars.
RSPCA Australia recommends against using these collars for several reasons. Firstly, they are often ineffective as dogs may not associate the punishment with the behaviour being corrected. Secondly, they fail to address the underlying causes of the unwanted behaviour, such as barking out of play or fear. As a result, the problem may only be temporarily masked, or the dog may become habituated to the collar, and the barking resumes. Lastly, barking can be a normal and appropriate means of communication for dogs, and the collar punishes them for this natural behaviour.
RSPCA Australia promotes the use of positive reinforcement as a preferable training technique. This involves rewarding a dog for desirable behaviour, such as stopping barking and remaining quiet, with treats, verbal praise, or play. This method has been found to be less stressful and better for the dog's overall welfare, as it provides an incentive for good behaviour instead of inflicting punishment.

Signs your dog is affected by ultrasonic sounds
Dogs have a much higher sensitivity to sound frequencies than humans, and certain sounds can be uncomfortable or even painful for them. While ultrasonic sounds are not typically painful, they can cause discomfort or anxiety in some dogs.
Ultrasonic training devices work by emitting a high-pitched sound when activated, imposing an unpleasant sensory experience on dogs. This falls into the category of "positive punishment", using discomfort to get a dog to behave in a particular way.
- Barking
- Whining
- Hiding
- Unusual activity
- Looking around in a confused manner
- Head tilting
- Running up to the area the sound is coming from
- Backing away from the sound
- Tail tucking
- Signs of nerves or distress
If your dog displays any of these behaviours, it is important to monitor their reactions and consider alternative methods.

Frequently asked questions
No, ultrasonic sound waves are not safe for dogs. They can be very loud and irritating to dogs and can even hurt their ears. Dogs have sensitive hearing and can hear frequencies up to 45,000 Hz, while humans can only hear up to 20,000 Hz.
If an ultrasonic device is bothering your dog, they will likely keep their distance from the object. They may walk or stand with their tail between their legs, tilt their head, put their ears down, drop their jaw, or show signs of aggression.
Instead of using ultrasonic devices, you can use firm verbal commands and try to understand the root issue of your dog's behaviour. Positive reinforcement training is considered more effective and humane than negative-reinforcement styles.
