535 Acme -'silent dog whistle'

I bought this exact whistle years ago for military K9 training and it was amazing. Recently I thought about having a strong recall for my cat and thought there is no reason this would not work great with my Cat. Disclaimer: My cat has a very high food drive. First time I blew the whistle the cat sought it out through sheer curiosity alone and he was rewarded. I repeated several times & and he learned that the whistle meant reward. I started using it for calling him to meal times and small to medium rewards in different locations of the house and at various times. He had to work to find me increasing the drive. I then paired the whistle to his name. We are doing very well with his training and still on a 1 to 1 schedule. We are going to start using his name more and the whistle less and put him on a variable reward schedule soon. The whistle will eventually be used on occasion to keep up the training but it will also be relegated to an emergency type recall for the cat (for example he gets out of the house and I absolutely need to recall him to get him back). This is a great whistle and a great tool for a training an animal that has a medium to high drive. If your animal (cat or dog) is low drive you might not get similar results but please do not make the mistake of blaming this amazing whistle. I am going to be purchasing my second whistle for my wife’s use today. I hope this helps someone make an informed decision.

I have in a pet-friendly apartment complex, which is fine, except for when my neighbor's dogs are randomly barking in the middle of the day for hours for no reason while I'm trying to get work done. I got this whistle as an attempt to surreptitiously train my neighbor's dogs to stop barking. If they start going crazy over there, I take the whistle and stand right next to my door before before blowing into it hard for a moment. The dogs would stop for a second, as if surprised by the noise, and then start barking again, to which I would blow the whistle again. This would repeat until they eventually stopped. After a few days of repeating this process, the dogs are much less barky during the day, and stop almost immediately in response to the whistle! The whistle has solved problem I needed it to without complaining to management or my neighbor! Great product!

i have an OLD Acme dog whistle that i've had since about 1985. It has been wonderful and still works great. I bought this "updated" version on the stated information that the new version is good up to two miles. IT IS NOT AUDIBLE UP TO TWO MILES AS ADVERTISED. I bought one but returned it because the sound was intermittent. I returned it and requested a replacement, thinking the first one may have been flawed. NOT SO. The replacement is also intermittent and dogs do not respond any further than 1/8 of a mile. I tested it with my sons two dogs. We had the dogs at 1/2 mile, clear line of sight. No response. Same thing at 1/4 mile. No response. Finally, at less than 1/8 mile they barely responded. If you need the distance, I cannot recommend this product. My dogs have responded to the old whistle up to 1/2 mile or more. My current dog who is well trained and responsive to the whistle also does not even perk her ears when she is a mile out. For short distances, this updated whistle may be fine. If you are looking for a long distance whistle as I was, this is not it. Acme used to make great whistles, this updated version is a huge disappointment for the price. Good luck.

I bought this whistle to replace an identical whistle which was lost. Whilst this whistle look similar, and does whistle, it is of remarkably poor quality. The threads all grind when you twist it. The set screw doesn't work. And the only way the cap stays on is if you have the set screw protruding out so far than it is loose and about to fall out. Really disappointed in seeing the quality control of Acme. The quality does not meet the definition of the word acme. My old acme 535 felt well machined, very smooth threads, everything worked brilliantly. This one is a real piece of crap. Feels cheaper than Chinese knock offs.

First, if you think a dog whistle is a magic whistle that stops dogs from barking, don't buy this or any other dog whistle. If you do, there's a 92% chance that you'll illustrate your lack of general knowledge by giving it a one star rating because, "it didn't work," and returning it. There's an 8% chance you'll illustrate your lack of general knowledge because the dog in question is one of the random 8% of dogs that stop barking when distracted, and you give it five stars because, "it worked." So, if this is your line of thought, google dog whistle; Galton whistle; and; classical, Pavlovian, or, respondent, conditioning; before you order anything to quiet your neighbor's dog. Yes, there are sounds that dogs may find painful to hear, so the noise can be used as negative reinforcement for negative behavior, but a dog whistle is not likely to produce one of these sounds. A dog whistle is a signal that's used to condition dogs, just like a command. So, whistling at a dog and expecting it to just stop barking is as silly as saying, "Alto!," to a barking dog and wondering why the dog didn't just stop. That said, this is a very nice whistle. As other viewers have pointed out, it's not inaudible throughout its range of pitch. But, it's not supposed to be. A pitch that's inaudible to humans, but audible to a dog, is only useful for a fairly limited short distance. At greater distances, a pitch needs to be used that is audible to humans. The Acme's pitch is adjusted by screwing a sleeve in or out. It has four graduation marks on the side and a set screw to keep it at the desired pitch. The whistle is well made, and a chain keeps you from losing the cap. I scientifically tested the inaudible ranges on my cats, whose ears perked when I couldn't hear anything. I have very nerdy and scientific cats. I don't have a dog. Oddly enough, in spite of my preceding rant, I'm planning on using mine to quiet my farging icehole neighbor's dog. This dog barks at everything, including air, and an inaudible pitch. My neighbor's definition of too much barking and mine differ significantly. So, I plan on sitting quietly in my backyard for several weeks, silently whistling this stupid animal into a frenzy on a regular basis. My neighbor's anticipated response is to quiet the dog. My diabolical plan is to let my neighbor condition the dog to not bark at the whistle. Getting to annoy the crap out of my idiot neighbor in the process is gravy on the biscuits. Once the dog is conditioned to not bark at the whistle, he should stop barking when I whistle. See the difference between a magic whistle and classical conditioning?

There has been another review mentioning that this whistle attracts cats’ attention as well. I was unaware of it. But one of my cats likes BIG adventures! From spring to fall he disappears in the woods for 1 to 3 weeks, comes back home for a few days, and leaves again. He covers an area of about half a square mile. So I was wondering what might help me to get him back home when I get worried. And I was particularly trying to find a method that is discrete, and not wake up neighbors when looking for my cat in the middle of the night. One of my friends suggested that I try a dog whistle. I purchased 3 different whistles on Amazon and this one was clearly the best quality whistle. Humans can hear it, but it is neither loud nor annoying. It probably does not have the 400 yards range in wooded and hilly areas, but my cats can hear it at a respectable distance. I always trained my cats to walk with me right from day 1 when they are only 2-4 months old. Every day they walk with me, pretty much like dogs, and they love it. Training my cats to respond to the whistle took no time. It just took a few walks, and whenever I called them to keep on walking I used the whistle at the same time. Recently my adventurous cat went for another big walk. After a week and a half I started to get worried as nights were getting cold we had several rainy days, my cat was not coming back, and two friends reported seeing him about a mile and a half away. So I sent postcards with his pictures to all residents around where I live. I received voicemails from people reporting having seen my cat, but usually too late and my cat was gone by the time I arrived on location. Finally after 15 days another resident called. I jumped in my car, drove immediately where he had been seen. I could not see my cat who was hiding. I blew the whistle and my cat came almost running at me. Back at home I purchased immediately a second whistle in case I lose the first one when my cat goes missing again.

When it works for me: Close range, when dogs aren't hyper focused on anything. When it doesn't work for me: When dogs are far away (even with the long distance setting) or hyper focused on something. What I like most about it: Sturdy; doesn't feel cheap. What it ultimately does: Gives me an absolutely piercing headache. To be fair, one of my eardrums is permanently punctured...so I don't know how much that comes into play. But it's pretty insufferable to me if I do any more than a couple of whistles. Other considerations: * Sound consistency is an issue for me. Sometimes when I blow on the whistle, it seems clogged and won't make a sound/whistle. So either the design is bad, or you simply have to be very precise and consistent with how you blow on it...which gets to be annoying when you need to get your dog's attention ASAP or immediately mark a behavior. * It's hard to keep the whistle on just one setting. I find myself having to twist it to the setting I want it to stay on each time I grab it since it's easy to accidentally twist into a different setting each time it's handled. Again, if one needs to quickly blow the whistle on command, this becomes an issue. You also can't even put the cap/lid back on unless you twist it down to the low setting. So if you always want to use the longest setting, you need to manually twist it back each and every time you take the cap/lid off. * As far as how audible it is to the human ear? As the whistle blower, you can hear a faint sound. For people nearby? It seems to be pretty inaudible to them based on my observations. I'd venture to guess they'd only be able to hear it if they're nearby, paying close attention, and it's in a relatively quiet setting. * Again, my only issue with the sound was how the pitch seems to pierce straight to my brain. It's not too audible, but it really hits me hard. I basically have to sit down for a little bit if I blow on it more than a few times.

I'm really not sure what all of the consumers who rated this whistle poorly were expecting, but they obviously weren't expecting anything realistic. This Acme Whistle #535 is a top-of-the-line training tool used most commonly with dogs, but is also the same bridge whistle used in training many marine mammals (such as dolphins and orca/killer whales) in several facilities all over the world. There is no such thing as a miracle product. With that said, there is nothing in the product description that claims that this is either a whistle to "annoy" a dog, a whistle make a dog stop barking, nor is the tool actually silent. There is no such thing as a silent training whistle; that defeats the purpose of its use. It clearly explains that this whistle is extremely high-pitched (with the option to adjust the frequency) and can be *almost* inaudible to human ears. In other words, it's not startlingly loud and irritating to us, but you can still hear it. For those of who who expect the Acme Silent Dog Whistle #535 to miraculously work immediately, you need to understand that nothing you do will have instantaneous results. This whistle is a TRAINING tool, not a quick fix. Every dog needs to actually be trained to respond to stimulus (in this case, the whistle) in order to expect results. If you want your (or even your neighbor's) dog to stop barking, you need to take the time to condition and train the animal! Granted, there are a *few* dogs that will respond immediately to the whistle, you just cannot expect that since it's not the usual reaction. Please keep in mind that the Acme Silent Dog Whistle #535 was originally designed for sport or working dogs. It is most commonly employed with field training dogs because this particular whistle is fantastic for long distances, it is much less irritating to the average human ear, and it is easily heard by the animal. In dogs, it is primarily used to give commands. In trained cetaceans (whales and dolphins) it is used as a bridge, which is a signal to the animal that it has completed the requested behavior correctly and will soon be rewarded accordingly. All that being said, the Acme Silent Dog Whistle #535 is an incredible training tool that is extremely reliable and useful, providing you know how to use it! As mentioned previously, it is excellent for long distance use and it is not loud or annoying to onlookers/neighbors, while still remaining dependably audible to the dog. It's stainless steel design is very durable and will last you a long time, as long as you don't misplace it (believe me, that happens a lot when trainers use a whistle for regular training and exercise sessions). This is, in my opinion, truly the very best training whistle that money can buy. I highly recommend the Acme 535 to anyone and everyone who utilizes whistles in their animal training!

A mi me funcionó bien con dos perros en un balcón de la casa de al lado. Al cabo de un tiempo usándolo dejaron de molestar

Article de qualité comme toujours avec Acme. Je tiens à remercier franchement le vendeur qui a pris le temps de me conseiller et m expliquer comment utiliser au mieux les 2 sifflets achetés. Super vendeur ! Merci.

great piece by Acme. just to explain, this is not a magic tool that you thing you will buy and you dog will listen or come back just by blowing in it. it requires training and patience, but work perfectly. thanks

La regolazione del suono del fischietto (su 4-5 posizioni) avviene mediante una filettatura a vite. E' poi possibile fissare la posizione scelta con una piccola vitina. In questo modo, però, è necessario allentare la vitina ogni volta che si cambia posizione (vicino - lontano). Sarebbe stata molto piu' comoda una regolazione a "scatti" in modo da non dover agire sulla piccola vite. Consigliato comunque.

Works very well. My sister's dog is getting deaf so this is great for recall
