Handheld Ultrasonic Dog Training Support
The MODUS Ultrasonic Dog Bark Deterrent is a compact training aid designed to interrupt a dog’s attention during certain unwanted behaviours. It produces a 25 kHz ultrasonic signal that is intended to be noticeable to dogs but generally inaudible to most adults.
The device should be combined with clear commands, appropriate rewards and consistent positive-reinforcement training. Results vary according to the dog’s hearing, age, temperament, surroundings and previous training.
25 kHz Ultrasonic Attention Signal
Pressing and holding the control button activates the ultrasonic output and illuminates the green LED indicator.
Intended to Interrupt, Not Punish
The signal is intended to briefly redirect the dog’s attention so the owner can provide a familiar command and reward the desired response.
Individual Responses Vary
Some dogs respond quickly, while others may show little or no reaction. The device does not work with hearing-impaired dogs and should not be presented as a guaranteed solution for barking or behavioural problems.
Up to 16.4 Feet of Operating Range
The manufacturer states an effective range of up to approximately 16.4 feet or five metres.
Maintain a Clear Line of Sight
Walls, furniture and other solid objects can block or weaken ultrasonic sound. Point the emission end toward the dog without placing it close to the ears.
Indoor and Outdoor Use
The portable device can be used in suitable indoor spaces and supervised outdoor environments. Loud surroundings may reduce its effectiveness.
One-Button Handheld Operation
The compact design fits comfortably in one hand and can be carried using the included wrist strap.
Automatic Output Limit
The device stops producing ultrasonic sound after approximately ten seconds of continuous activation. Use short activations rather than holding the button unnecessarily.
Green LED Indicator
The green light confirms when the button is pressed and the ultrasonic output is active.
Combine with Positive Reinforcement
For responsible use, the ultrasonic signal should be followed by a clear command and a reward after the dog performs the preferred behaviour.
Keep Training Consistent
Use the same verbal cue and reward pattern during each session. Avoid shouting, striking or frightening the dog.
Identify the Cause of Barking
Barking may be related to fear, pain, separation distress, territorial behaviour or unmet physical needs. Addressing the underlying cause is more important than simply interrupting the sound.
