Introducing the HKM-8911421 Ultrasonic Adjustable Dog Training Whistle, a cutting-edge tool designed for effective bark control and reliable recall for your canine companion. This metallic dog flute boasts a sleek design and is crafted from high-quality brass electroplated nickel, ensuring durability without compromising on style. Weighing just 12 grams, it’s easy to carry and handle during training sessions.

What sets this ultrasonic whistle apart from a regular one is its unique ability to emit sound in the ultrasound range. This means it can travel long distances without interference from external noises, making it ideal for training your dog even when there are distractions. While humans may not perceive the sound, dogs can hear these ultrasonic waves distinctly, enabling them to receive clear and precise commands.

One important aspect to consider is that dogs require training to respond to the whistle effectively. Initially, they might not instinctively know that the sound signifies returning to their owner, but with patience and practice, they will learn to associate the sound with the desired behavior.

The HKM-8911421 also features an adjustable volume. By simply rotating the adjustment tube and changing the position of the nut, you can customize the pitch to suit your dog’s preferences. This flexibility allows you to find the perfect tone that resonates best with your pet, making training sessions more effective and enjoyable for both of you.

Whether you are looking to enhance your dog’s recall abilities or encourage better bark control, the HKM-8911421 Ultrasonic Adjustable Dog Training Whistle is an essential tool for every dog owner committed to building a strong training foundation.

What's the difference between this and a regular whistle?

The sound blown by the dog flute belongs to ultrasound, which has a long propagation distance and is not disturbed by external sounds, which is very suitable for long-distance recall of dogs.

The sound of the dog whistle is not very loud, can the dog hear it?

Ultrasound is beyond the range of the human ear, so only the tubular sound of the dog's whistle can be heard. But the dog's ear can receive ultrasonic waves, and for dogs, it can receive bright and accurate instructions.

The dog doesn't respond when it hears it. What's going on?

Dogs are not born knowing how to play the dog whistle to return to their owners, which requires training.

Can I adjust the sound volume?

The size of the space in the rotating adjustment tube can be adjusted by adjusting the position of the nut to adjust the pitch of the sound, so as to achieve the purpose of adjusting the volume. Each dog has its own pitch, choose the pitch that the dog likes to use for training half the work, twice the effect.

Dog loved it
Size: One-Size-for-Most
Great! My dog loves taking it outside at night so he can see where it goes easier. Super bouncy, he has had it for over a year now and still not destroyed. Perfect size for his mouth too and easy to clean.

Light up and glow in the dark ball
Size: One-Size-for-Most
Definitely my girls favorite ball πŸ˜€. It disappears and I have to buy another one or she goes nuts. Glows in the dark, brighter with more sun. The bounce light up don’t last a real long time, too quick to quit for her but still loves it.

Durable & Bright - Great for Heavy Chewers
Size: One-Size-for-Most
Pros: Extremely Durable: Survived an aggressive chewer where tennis balls failed. Dual-Visibility: Features both internal flashing lights and a glow-in-the-dark "chargeable" surface. Perfect Size: Fits comfortably in the mouth of a 40lb medium-sized dog. Same size as a tennis ball. Cons: Battery Life: Unsure how long the internal flashing lights will last (though it has held up well so far).

Great for night time play!
Size: One-Size-for-Most
This ball is great! It is a 2-for-one light up feature so we love the flashing lights and if she drops it in the snow after those lights stop, we can still find it because of the strong glow that gets its charge from the flashing LED lights. Our first one lasted a few years, we lost it on a trip so now back for our second one so we can keep the night time fetch going! She is a golden retriever for size reference. Any bigger of a breed and I would worry it might be too small for her mouth. It’s a bit smaller than a tennis ball. Just don’t make the same mistake I did and let them have it in the house at night, she walked up to my bedside while I was asleep one night and squeezed it to activate it. Those lights are so bright it was a rude awakening!

Good option for playing at night
Size: One-Size-for-Most
This ball is a good option if your dog likes to fetch at night. It stays lit for about 20 minutes or so, but that is me only leaving it out of the counter, being "charged" by whatever house lights are on. My dog isn't a big chewer, but it seems as though it would hold up well. I like that it is easy to rinse and clean. It seems to be a good value.
