Acme Dog Whistle by J Hudson & Co.

Last updated: 24 October 2026

What silent means

Not silent. The name is a hundred years of marketing rather than a description. A silent dog whistle produces a tone at the top of human hearing and above it. That is the range where a dog hears easily and most adults hear little or nothing.

Two things follow from that. Adults with good high-frequency hearing, and most children, will hear it perfectly well, so a household expecting genuine silence is going to be surprised. And because human high-frequency hearing declines with age, the person blowing it often cannot tell whether it is working, which is why the adjustable pitch matters.

The adjustment, and what to do with it

The threaded end screws in and out to change the pitch. Acme's argument for it is that hearing varies between animals, so you tune the whistle to your own dog. Different settings then let you teach different commands.

In practice trainers use it the other way round. They find a setting that works, mark it, and never move it again. The whole value of a whistle over a voice is that it sounds identical every time. A voice carries mood and a whistle does not, which is why a dog will recall to a whistle across a field when it will ignore a shout.

Set it, mark the thread with a scratch or a dab of nail varnish, and leave it. A whistle that has drifted half a turn is a new command to the dog.

The two-mile claim

Acme put the effective range at up to two miles, or 3km, and they add the condition: "subject to weather conditions, and the abilities of the dog and the trainer".

Read the second half as the main clause. Two miles means a still day, open ground and a dog already trained to the whistle. On a windy hillside with a distracted spaniel the honest number is far smaller. The figure tells you the tone carries. It does not tell you the dog will come.

J Hudson & Co., and the whistles you already know

Joseph Hudson began making whistles in Birmingham in 1870. The company still trades from Barr Street in Hockley under the same name, and describes itself as made in England since 1870, across five generations.

Two of its products became the generic name for the whole category. The Metropolitan was the whistle the police carried, replacing the rattle. The Acme Thunderer is the pea whistle used by referees, and it remains the most-produced whistle in the world. Acme's own account of it is neat: "Nobody bought a whistle; they bought a Metropolitan and a Thunderer."

Hockley is Birmingham's jewellery quarter, and the firm's own copy calls the city "the City of 1001 trades". A small brass and nickel object made to a fine tolerance is exactly what that quarter was built to produce, and the whistle is still made there.

About the 1935 date

Labour and Wait describe this as "the first ever silent dog whistle, invented by Acme in 1935", and the claim comes from Acme. Acme's own website does not publish the date on its current pages. So it is a maker's claim rather than a documented one, and we write it that way.

What is documented on Acme's own site is the 1870 founding, the Birmingham address, the five generations and the Thunderer. Those are the facts the page rests on.

Who it suits

Anyone training a dog to recall at distance, which mostly means working dogs, gundogs and anybody whose spaniel treats a field as an invitation. It suits a new puppy owner better than a £28 toy would, because whistle recall is easier to teach early than to retrofit.

It is a good present precisely because it is the sort of thing people mean to buy and do not. It also lasts: a nickel-plated brass tube with one moving part has very little to go wrong, which is the case for spending £28 rather than £6.

It does not suit a household that wants a quiet garden, for the reason set out at the top. And it does nothing on its own: a whistle without training is a whistle, and the training is the gift. Our gift guide for dog lovers covers the rest of the kit.

Acme dog whistle FAQs

Is a silent dog whistle actually silent?

No. It produces a tone at and above the top of adult human hearing, so dogs hear it clearly and most adults hear it faintly or not at all. Children and adults with good high-frequency hearing usually hear it perfectly well.

How much is the Acme dog whistle?

£28 at Labour and Wait, supplied with a chain, checked on 6 September 2026.

What does the adjustment do?

The threaded end screws in and out to change the pitch, so the whistle can be tuned to a particular dog and different settings can carry different commands. Most trainers find one setting and mark it so it never moves.

How far does it carry?

Acme put it at up to two miles, or 3km, and add that it depends on the weather and on the abilities of the dog and the trainer. The second half of that sentence is the important half.

Who makes it?

J. Hudson & Co. (Whistles) Ltd of Barr Street, Hockley, Birmingham, trading as Acme, making whistles since 1870. The same firm makes the Acme Thunderer.

Was the silent dog whistle really invented in 1935?

That is Acme's claim, repeated by retailers. Acme's current website does not publish the date, so we attribute it to them rather than stating it as established fact.

Will it work on any dog?

The tone will be audible to almost any dog with normal hearing. Whether the dog responds is a training question, not a whistle question, and no whistle solves it on its own.
