The Acme Silent Dog Whistle 535 is the ultimate silent dog training whistle. 

No "silent" dog whistle is truly silent. If it were nothing would be able to hear it!

The word ‘silent’ is written in inverted commas because you can hear it, BUT only just. What your dog hears is really loud and travels up to 1.5km.

Adjustable through a wide range of frequencies using a screw piston mechanism enabling you to tune it to suit your own dog, this is the most versatile silent dog whistle that can be used with all breeds.

A booklet is supplied with each one giving easy instructions on adjusting the whistle and training your dog. 

The whistle is designed with special air directors to tightly control the frequency produced and generates over a mile of sound with minimal effort.

This is an adjustable frequency whistle. 


  • The first ever "Silent" dog whistle.
  • Brass nickel plated.
  • Adjustable frequency - between 5200 and 12800Hz.
  • Protective end cap.

Customer Reviews for Acme 535 Silent Dog Whistle

  • 5 out of 5 Silence is highly recommended

    Newitts Verified Purchase (27 Nov 2022)

    Great whistle, beautiful item with very handy lid , easy to keep in pocket and our dog got to grips with it really quick.
    Would recommend in urban areas for quietness or if you just need a long distance command for your dog to return. Dogs give you a funny look first time you use it but soon get the hang of it. Doesn’t seem to bother them if they know it’s not for them either which was reassuring. We can call one back with the whistle while one next to us carries on snoozing.

    Whistle feels a little heavy on a lanyard but is compensated by its excellent quality. Ideal for training dogs whereby not attracting attention from neighbours.

  • 4 out of 5 Acme silent whistle

    Newitts Verified Purchase (9 Apr 2016)

    I bought 3 of these in the same order. 2 are fine, but the other one is simply harder to get a sound out of. Same pitch, just more difficult to achieve the same volume. Don't know why or how to fix it. Pity, as I have always used these as a professional Gundog trainer and recommend them to my clients,. Never had a problem before, perhaps I was just unlucky.

  • 5 out of 5 Acme 535 Silent Dog Whistle.

    Newitts Verified Purchase (2 Nov 2015)

    The whistle arrived safely a week after ordering. I'm very pleased with it.
    The whistle is a little heavy when hung around your neck, but it's well engineered, solidly made, and works a treat.

  • 5 out of 5 Quality at a Very Good Price

    Having read quite a lot of reviews about various makes of Silent Dog Whistles i decided on the [reassuringly expensive?]Acme 535 Silent Dog Whistle. Other generic makes had truly appalling reviews from average to abysmal! The maxim "you get what you pay for" isn't always true but in this case it certainly is. The Acme Whistle is by far the most expensive make on the market but the build quality speaks for itself. i don't see the point in paying a fiver for something that falls apart after a few days when you can buy quality that lasts a life time: its a no brainer and simply false economy. If you want a brand leader, quality Dog Whistle [silent] then the Acme 535 is the way to go and Newitts are without doubt, at the time of writing, the best price in the UK. NB. Though effectively 'silent' the whistle does emit a low note to help you to hear your command and signal duration. Very handy!
