I work one dog at a time to learn what command is associated to the number of times I blow the whistle. Then when all 3 are together, they respond the same. I encourage you to watch the video, it's very helpful. Great product!

Bought this as a gift for my daughter who has a pair of bulldogs. She tells me that she can recall them easily with this device.

Made well...Easy to set up!

I was so happy to find that the first time I blew this whistle my dogs came running to check it out. It was so easy to continue their interest when I used their favorite treat to reward and train them to come running when I blow the whistle. The goal is to get them to me when we're ready to leave the huge dog park.

My dog is 4 years old. I changed from an Acme Thunderer to the Acme Silent Dog Whistle hoping she would respond. She became tuned in instantly and I would say that her recall is now instantaneous. That silent whistle is truly sensational.

Easy to emit a tone, but indoors people can hear the whistle between floors of the home. Not a deal breaker and the first time my dog heard it he jumped from a sleep barking as if the UPS truck was coming up to the door. I am using it for recall when I do not have an e-collar and hope to transition to use it with the collar to signal him to change directions. I wanted a whistle that is adjustable and unique from others in the field. This will do the trick.

Looks like this whistle is well made, it just doesn’t work for me. It is not silent. Dogs don’t seem to respond to it. It was pretty expensive.

Not the cheap unit seen all over Amazon. This is a well manufactured whistle that's easy to use.

I've used silent whistles for my dogs for decades now and, although I've never owned one that I'd complain about, this one is by far the best.

I like the quiet whistle and my rottie responds to it very well... until it stopped working. I've cleaned it and soaked it (in case any air passages are blocked) but it still won't work. Considering the cost... what else can I do to get it working again?

I think the whistle works well. It sure is good quality.

Works well…. My dog responds to it very well. I bought 2 and gave one to a friend.

Honesty is the best polacy ! Good on yah !

So far so good. Not too obnoxious and gives me range for my GSP to cue off of. Needed to attach a proper lanyard though.

This whistle replaces my orange school yard type whistle which can blow a humans ears out. I love that the dogs instantly respond to it and even I can hear most of the frequencies without hurting my ears. Now we move on to using the same commands from the loud whistle to this quiet version.

I have not been able to have my dog hear the silent whistle when he is loudly barking at the delivery people

I bought this for training our dog and it works great. I had originally purchased a cheaper one, but our dog barely acknowledged it. This one gets his attention every time! It’s very well made and worth the extra expense.

Solid, easy to set

Really good experience with this product. The puppy hears this whistle and it diverts his attention to me from even the most distractive activities. It has helped me with training him to respond to commands.

I use this whistle because my GSPs seem to respond much better than to other whistles I have tried. When my dogs are out at one or two hundred yards they respond and I don’t put up with the uncomfortably loud sound necessary with other whistles.

This is the first dog whistle that works. Quality construction.

This was exactly what I was looking for. I have Malamutes - obedience is at best a negotiated experience with this breed. I have a pair of littermates which is an even greater challenge because they are bonded as tightly to each other as to their human pack. They’re really good outside the fence as long as they are harnessed and on leads, but if they slip their leads, off they run with ears tightly closed to any and all words that come out of our mouths. My son was shopping in Cabela’s one day, saw a dog whistle, and thought that would be worth trying out. We tried getting them to come using three blasts of the whistle followed by a treat when they showed up and it worked beautifully. Then the whistle rolled off the table and got sucked into the vacuum. It wasn’t the greatest whistle and didn’t adjust for squat, so I went hunting for a good, durable whistle that I could adjust to the perfect frequency for our two wooly adventurers. This whistle is perfect. It’s one of the only ones I’ve tried that goes high enough to be pretty much silent - the frequency that catches my dogs’ attention best. I like the cover which, contrary to many reviews I’ve seen, is easy to pull off and put on. It’s also really solid which just adds to its feel and durability. The dogs actually got hold of it once and took it out to the yard. All it needed was a quick wipe down and it was good as new (they had already eaten up two other whistles that were plastic and one that was metal but not sturdy). They can be outside enjoying the yard, upstairs snooping in wastebaskets, or even all the way up in the attic snoozing in a sunny window, but, when I give three blasts on the whistle, they come running. We’ve got them pretty consistent within back yard and home and are going to move to dog park training. Hoping that gets consistent enough that we can attempt free walking outside the house so that we can count on them stopping and returning if they slip away from us. Anyway, I’m really happy with this whistle - solid, adjustable, consistent (not all whistles are), and can be attached to a lanyard to wear around your neck with outside.

I really like this Acme Silent Dog Whistle - #535. I like the fact, too, that it has its own cover. I am training my sometimes stubborn 9-month old German Shorthaired Pointer to come to this whistle. My GSP reacts and comes!

Product was quality, and just what it said it was .Had a little trouble with screw for tone adjustment but all around good product. I just made the wrong choice for my dog, she doesn't like it. I have been using a whistle with a pea and wanted something without. Will try another style.

My shorthair pointer responds way better to this whistle then any other I have used. Even in the wind or long distance she hears it and responds to it. Very good results.

This a terrific dog whistle! Adjustable pitch and excellent range makes it useful every time I take my two rowdy young dogs to the 10-acre woods in our favorite dog park. It even worked at a distance calling them back from chasing deer, which is very impressive.

I like it but it's not foolproof. Sometimes it takes the dog a while to respond.

Works like a charm without disturbing my neighbors. She comes when called and obeys other commands, after having been trained to the commands, of course. she actually seems to respond to the higher pitch better than the regular whistle.

My Dog responds perfectly to this whistle. I am happy with it. This my third replacement. I am having this one engraved so if found, it can be returned.

Very pleased with both whistles I ordered. Would recommend them.

The whistle works wonderfully well, but the secret is Steve's instruction for training dog and owner how to use it. It is not magic but if you do what Steve says, it works.

I love it. My pup has started to comply.

Just got it. Still a work in progress. A puppy, she responds most of the time, till distracted.

In my opinion, this is a well-made, high quality whistle. I use it to call my cat and it stimulates a response better than my voice. I had trouble removing the cap as I have parts of fingers missing on my left hand. I discovered that removing the chain solved the problem. The chain is just a little too short to allow the amount of pressure needed to remove the cap. Getting a lanyard would be a good replacement for the chain. This whistle is by far superior to the one I bought at a large chain store that never worked at all.

Very good quality!

I can't seem to get my dogs to hear it! Information on web site said that a person could only hear air passing through the whistle. However, once I tightened the screw to set the whistle for long distance and tone, it began to have a high pitch whistle, but the dogs don't seem to hear it. I will keep trying to get them to respond to this silent whistle.

Hard to hunt with.

Seems to work well with the dogs. Took some extra training with them to respond consistently. Don't like the small mouthpiece, makes it hard to hold in your mouth and blow when you are working with the dogs. It takes some getting used to to make it work. I use it in the field to make my dogs quarter in front.

Expensive, but incredibly well made. Skip the one made in the far east and buy the original. Been using them for 40 years, and it's still the best.

Well made, but a little less comfortable to use than the Acme plastic whistles. We are testing higher frequencies for longest distance.

Much more solid construction than others I've looked at. Easy to blow. Adjustable frequency. And, best of all, my dog responds from at least 100 yards away.

I had a little problem removing the cover on the whistle, but now have the little problem solved. It works great! Thanks

I'm still at the very beginning of training with it. Puppy is not quite 16 weeks yet. He is blind, though, and I feel this will be an excellent training tool, especially when there is a great deal of peripheral noise that is confusing to him.

Made of good quality materials. The chain feels solid. The adjustable pitch is very easy to change. It always gets the attention of my dogs, and they were quick to realize what it meant.

It is an amazing product. I love it!! Used it for my hound. Works amazing!

Works with our dog out to about 100 yards. I think beyond that the background noise from a highway distracts the dog. Also our dog is barely 2 years old and I think she ignores the whistle when she is on the trail of some critter. I think I may need to get a training collar to increase the distance for alerting the dog.

All I can say is IT'S GREAT!

Best whistle on the market, silent or ear buster.

I had used just a regular whistle, but needed something that didn't hurt my ears and had more distance. The dogs are responding to the silent whistle after some training.
