Dog whistles aren’t the most commonly used item when it comes to training dogs, so it’s not a surprise if you haven’t heard of it or aren’t familiar with the item. So what exactly is it?

As the name suggests, its basically a whistle made to be used on dogs. It has a high-pitch sound, clear enough to catch your dog’s attention any time you want without actually causing any harm to them. 

So if your dog is constantly barking or exhibiting hyperactive behaviors, then you should consider buying a dog whistle. This can also act as a security measure for you in case your dog wanders away from you or gets lost. 

How does a dog whistle work?

Dog whistle works similarly to any regular whistles, but the biggest difference lies in the fact that it is specifically made for dogs only. So how does it work?

Dog whistle produces a very high-pitched sound which humans can’t hear, but dogs and so does other animals as cats can hear. This particular dog-made frequency engages the dogs in becoming more attentive. Hence, it is generally used in dog training.

Dog whistle frequency

Dog whistles are also referred to as a silent whistle. The name is partly due to the fact that dog whistles emit a specific sound frequency that the human ears can’t hear. 

This frequency is a very high-pitched sound most popularly known as the ultrasonic range. This pitch is so high that only animals like dogs, cats, etc. can hear. 

Most dog whistles offer adjustable frequencies, while some come with ready-to-use high to medium pitched sound frequencies. Since every dog reacts differently to different frequencies, whistles with adjustable frequencies are more recommended in comparison.
