Question: Is there any chance an elderly dog who is mostly deaf might hear and respond to this whistle?
Document: Just like other reviewers had said, this is the high end of dog whistles. This is no joke. It has different settings as you twist the middle and it gives off different pitches. I've never seen my dog respond to anything so quickly as he does this dog whistle. I got this dog whistle mostly because our dog loves to chase and bark at the dogs next door along the fence. He gets so fixated at chasing the dog that he doesn't hear us yelling to him to come inside.
does as it says,but does not seem the dog can hear it,but not your fault...maybe dog is deaf. thank you.
I bought this after the reviews convinced me it was much better than a cheap whistle. My dog can hear it and I've played around with the adjusting, but I'm not sure I have it adjusted correctly. We're still working on training with it, but if you get it and aren't experienced with whistles it might be worth working with a trainer to make sure it's set up the way you need it.
This is the best dog whistle I've ever seen. The two halves come together to encapsulate the whitlse while not in use, and are connected by a sturdy chain to keep from losing it. Stainless steel, with a smoothly threaded construction for easy changes in pitch and tone.The popular misconception that dog whistles are supposed to be capable of frequencies that humans can't hear, but dogs automatically respond to, makes most of the negative reviews of this whistle unfairly skewed.Dog whistles are not silent.
I live on a rural property (80 acres) and bought this whistle to call my dogs home from the neighbor's property. I've successfully trained them to respond to the whistle and they do so when close (within about 500 feet). Beyond that range, they do not respond. They act as though they don't hear the whistle which I suspect is actually the case. If I blow with more pressure (to increase volume) the whistle doesn't work at all.
If you hear a fuzzy or airy tone you are doing it incorrectly.Try for a pure, clean tone.Larger dogs respond to a lower tone, and smaller dogs the higher tones.This is why this whistle is so fantastic because you adjust it to fit your needs.Now, when you hear the dogs bark, get to a location near them, like an open window or door. Take a deep breath and blow out a pure tone as long as they are barking.
My little dog is 13 and going a bit deaf. I have an acre back yard, fenced in and was having a time getting her to come back. she hears this and comes running now. Thank you !! !
They require training. This whistle comes with a pamphlet that explains how to train your dog to respond to the tones you choose.I bought two, just in case they ever take them off the market for whatever reason.
I had tried a cheaper dog whistle and apparently it was not at the right frequency, and the dog did not respond. I liked the fact that this whistle was adjustable. With a little adjustment the dog responded right away
The product is well made and built to last. One adjusts the frequency by turning the inside cylinder. Ridges on this inside cylinder allow you to return to a precise position. By trial and error you can determine which position is most effective. Even though my barking dog doesn't stop barking when we blow the whistle, he does respond to it and usually comes to us a few seconds later when the dog or person has moved on.
Answer: yes
