Product description
This compact ultrasonic trainer from Holercoco helps reduce persistent barking and other unwanted behaviour by emitting high-frequency tones that catch a dog’s attention without physical contact. It is portable and easy to use at home or outdoors, offering a humane alternative to shock collars and loud whistles.
Key Points
The unit uses dual ultrasonic modes with fixed and variable frequencies to interrupt barking and encourage recall. It works at distances up to around 65 ft, which makes it suitable for gardens, parks and apartment balconies where a neighbour’s dog may be noisy. The device is rechargeable via USB and the manufacturer states a full charge takes about two hours with an estimated operational span of approximately 60 days on typical use, and a standby time up to 180 days.
Operation is simple and immediate, so it can be used during short training sessions. Aim the device towards the dog when they bark, give a firm verbal cue, and reward correct responses. Over time the sound signal is intended to help the animal learn to stop the unwanted behaviour without causing pain. Consider that it will not be effective with dogs that have hearing impairment, with puppies younger than six months, older dogs beyond eight years, or in very noisy environments.

Usage Recommendations
Use the device as part of a consistent training routine. Start at short distances and combine the sonic signal with a clear verbal command such as "Stop" or "No". Praise or give a small treat when the dog responds correctly to reinforce the behaviour. For outdoor use keep the device aimed directly at the dog and be mindful of obstructions that could reduce the effective range. 🐶
Remember that behaviour change takes time and the manufacturer advises contacting support if no improvement is observed after around two weeks of consistent use. The device is not intended to replace professional behaviour consultation in cases of severe aggression or anxiety. 🔋
