Holercoco Anti Barking Device for Dogs
Product description
If your dog barking is becoming a daily headache at home or outdoors, the Holercoco anti barking device is built to help you regain control without relying on collars or harsh methods. This ultrasonic stop barking device uses high frequency sound to capture attention during barking, making it a portable training aid you can bring out when needed. It is described as safe and humane by the manufacturer, with no shocks, vibrations, or skin contact. 🐕
The essentials

The Holercoco anti barking device for dogs is an ultrasonic deterrent designed to interrupt unwanted barking and related bad behaviour such as biting and jumping, according to the product description. Instead of using electric shock training, it focuses on emitting ultrasonic sound signals intended to get your dog to pause and respond to your cues. The device is portable, so you can use it around the house or when you are out in the garden, where barking can be especially disruptive.


It also comes with practical guidance for training. You point the device towards your dog when barking occurs and give a firm verbal command like Stop or No. When your dog responds, the manufacturer suggests reinforcing that behaviour with gentle praise or a small treat. Over time, the idea is to reduce repeated barking and improve daily manners.

There are also clear limitations to keep expectations realistic. The manufacturer notes it is not applicable in certain situations, including noisy surroundings and when the dog is hearing impaired, as well as cases with multiple dogs together or dogs under 6 months and over 8 years. Taking these points into account can help you decide whether this is the right type of training support for your household.
Key points



The device is designed around ultrasonic emitters and multiple frequencies to improve coverage and capture attention during barking episodes. The description highlights large ultrasonic emitters and expands coverage compared with standard single transmitter devices, with the aim of curbing unwanted behaviours quickly. It uses dual ultrasonic frequencies, including a fixed 25 kHz component and a variable 25 to 30 kHz component, delivered as high frequency sound signals.
Safety and humane training are a major part of the positioning. The manufacturer states it uses no electric shocks, no vibrations, and no noise output in the way a whistle would be perceived, and that it makes no skin contact. It is also claimed to not impair canine hearing, with the intent that it is harmless to both dogs and humans. That said, it is always wise to introduce any training device gradually and monitor your dog’s comfort.

Portability is another standout feature for day to day use. The unit is compact and lightweight, and it includes a wrist strap so you can keep it ready while you manage behaviour. Coverage is described as up to 50 ft control range, which can be useful for indoor moments too, especially if your dog tends to bark from another room or near doorways.


Battery life is described as long lasting, supported by USB charging. The manufacturer states it fully charges in 2 hours and offers about 60 days of range, with standby time up to 180 days. If you want a deterrent that does not demand frequent charging, this long standby claim is a meaningful consideration.

Who it’s for
It makes sense if you want a portable, humane style barking deterrent that you can use quickly alongside verbal commands and positive reinforcement. It is a practical fit for households where you want to address barking at home or reduce disturbance from outdoor barking, with the device described as safe and no contact. You may want to consider it if you are looking for a sound based training aid rather than a collar.
It might not be a great match if you regularly deal with noisy surroundings, because the manufacturer specifically lists that as a situation where the device is not applicable. It is also not recommended for hearing impaired dogs, for use when more dogs are together, and for dogs under 6 months or over 8 years, based on the stated limitations. If any of these scenarios apply to your situation, it is better to look for a different behaviour support approach.
