The idea of purchasing a dog silencer may initially seem like a bizarre concept. Who wants a dog who doesn’t bark? Isn’t part of the reason to even get a dog so you’ll have a four-legged protector who can be seen and heard?
Not everyone agrees with this sentiment though. According to New York Times, while power tools and machinery can wake people up as early as 8 a.m. and as late as 9 p.m. (weekdays and holidays included), barking dogs fall under “unnecessary noise regulations.”
In certain towns, a barking dog can fall under the category of a noise or nuisance laws. And depending on how overly aggressive the dog is, these kinds of fines and police complaints can be costly. This is one of many reasons why finding the best dog barking silencers may be necessary.

Key Information About Dog Silencers
What is a dog silencer?
A dog silencer is a humane way of getting your dog to quiet down for the sake of your home, your neighbors, and even while you’re on an outdoor trek (i.e., camping, hiking, etc.) These devices are available in various shapes and sizes that can train your own dog, stray dogs and even other types of animals (ex. cats, baboons, etc.) to stop making excessive noises. Brands often mention if each product has been recommended and/or tested by dog trainers to confirm how useful it is.
Types of dog silencers
Dog silencers can come in a variety of ways, including hand-held remote devices; sturdy devices that can be hammered into hard platforms such as trees or fences; and alarm-like electronic devices that can sit on a flat platform similar to an alarm clock. Depending on the device’s power and specified level, the ultrasound can be heard as far as 50 feet away. There are also dog silencers than can attach right to your dog’s collar, eliminating the risk of losing the remote control device. Battery type and battery life may differ; pay attention to standby options to conserve battery time and avoid the device eating up your batteries when not needed.
Benefits of dog silencers
While there are dog silencers that can electrocute a dog or temporarily hurt him, ideally the goal would be to make the process of silencing a dog’s excessive barking quick and painless. This is why humane options and primarily no-shocking options were specifically chosen for all 12 devices above. Dog silencers also come in handy to avoid dogs who excessively whine or howl for no apparent reason.
Using dog silencers on a dog-by-dog basis
Of course every dog is different and may not be sensitive to the same amount of noise as another. (The human equivalent maybe how you would react to a blaring ambulance or fireworks compared to someone else. Some pets may eventually get used to the sound if heard enough while others will be irritated by it each time. This is why a variety of choices were given. Where one dog barking silencer may not work on one dog, another one will. Even better, it can be used on multiple dogs at once for easier training techniques.
Key Techniques while using Dog Silencers
It is completely up to the owner of the device regarding how often the dog barking silencer should be used. Some devices require a dog bark excessively for a long or short period of time. For example, one device above takes up to four seconds of barking before it will sound the alarm. For a speedy mail carrier, this may not be enough time. But for another one, this may be just the amount of time needed to reach the porch.
Pay as much attention to what a dog barks at as you would with how often to use the device. It’s imperative that manual devices not be used when a dog is not barking. Otherwise, he or she will not understand the connection between excessive barking and this alarming sound. For reasons like these, this should never be used by small children who may attempt to “play” with the manual versions. (Automated versions have a built-in sensor to measure volume.)
Having a dog silencer is a completely individual decision. Some dog owners may find that they miss the sounds of their noisy dogs. Others may find their dogs not being noise boxes to be instant relief. While the dog more than likely won’t mind not hearing the ultrasonic sounds, the short amount of time that the noise happens makes these devices more humane and doesn’t deter your dog from other playful behavior.
Most importantly, it eliminates harsher techniques such as shocking or physical pulling. It’s safe to say if your dog has to choose between the two, the ultrasonic sound would be the preferred method. And even for those who just want to get a good night’s rest or to be able to walk without carrying a huge stick and pepper spray, dog silencing devices even the playing field for peace among your noisy neighbor’s pets, animals in the wild, and stray dogs and cats.
