A good recall is the most valuable skill a dog can learn, and a whistle is one of the best ways to build it. Unlike your voice, a whistle sounds the same every time, whether you are calm or cross, and it carries much further over fields, woodland and wind. Dogs learn to recognise the note quickly, and many owners find a whistle far easier to use than shouting.
We have compared five dog whistles currently available on Amazon UK, all from Acme, the Birmingham maker that has set the standard for generations. They range from the classic pealess 210.5 and 211.5 to the trial-grade 212 and the adjustable silent 535. We explain who each one suits, what we like and what to watch out for.

Individual Product Reviews
Acme 210.5 Pealess Whistle
Best for: gundogs, spaniels and everyday recall
The Acme 210.5 is the classic dog whistle, made in Birmingham and used by trainers and shooting folk the world over. It is a pealess whistle, which means there is no pea inside to stick or freeze, and it produces a clear, high-pitched note that carries a long way.
A whistle is useful for recall because the sound is consistent and cuts through wind and distance better than the human voice. Your tone of voice varies with your mood, whereas a whistle always sounds the same, which makes it easier for a dog to learn.
It costs around £11 with a lanyard and averages 4.5 out of 5 across more than 6,000 ratings. It is the best all-round choice for most owners.
What we like:
- Long-established and reliable
- Consistent sound that carries
- Pealess, so it works in wet weather
Worth knowing:
- A high pitch that some dogs, and some people, find sharp
- A single fixed pitch
Specifications:
- Type: pealess whistle
- Frequency: around 6200 Hz
- Comes with: lanyard
- Brand: Acme
Acme 211.5 Whistle
Best for: long-distance calling and working dogs
The 211.5 is a slightly lower-pitched Acme whistle, tuned to about 5700 Hz. The lower note travels further and is less shrill than the 210.5, so it is a favourite with people who work dogs in open country.
It is a good choice for owners who prefer a softer note or who want a whistle for a dog that is sensitive to very high pitches. Many trainers keep both a 210.5 and a 211.5 so they can use different notes for different commands.
It costs around £11 with a lanyard and averages 4.6 out of 5 across nearly 6,000 ratings.
What we like:
- Lower, carrying note
- Excellent reviews
- Comes with a lanyard
Worth knowing:
- A slightly less sharp sound may be harder to hear for a dog in some conditions
- Still a fixed pitch
Specifications:
- Type: pealess whistle
- Frequency: around 5700 Hz
- Comes with: lanyard
- Brand: Acme
Acme 535 Silent Dog Whistle
Best for: barking control and quiet training
The 535 is a different kind of whistle. It is an ultrasonic whistle that is largely inaudible to people and can be adjusted to different frequencies, so you can find the pitch your dog responds to best.
Adjustable frequency makes it useful for dogs with different hearing ranges, and the quiet sound is ideal when you do not want to disturb neighbours. It is a training tool rather than a long-distance recall whistle, and it needs some patience to set up and test.
It costs around £29 and averages 4.0 out of 5 across nearly 400 ratings, making it one of the more divisive options because results vary from dog to dog.
What we like:
- Adjustable frequency
- Quiet to people
- Brass, solid build
Worth knowing:
- More expensive than the other Acme whistles
- Results vary, and it needs some experimentation
Specifications:
- Type: adjustable silent whistle
- Frequency: adjustable
- Material: brass
- Brand: Acme
Acme Pro Trialler 212
Best for: trials, gundog work and precise training
The Pro Trialler 212 is the Acme whistle designed for gundog trials and serious training. It has a lower, cleaner note of about 5200 Hz and an easy, comfortable mouthpiece, and it is made to be used all day.
Its low frequency carries well over a distance, and its softer tone makes it easy to blow gently for quiet commands. It is also a good choice if you want a whistle that lets you control tone and volume with your breath.
It costs around £15 and averages 4.6 out of 5 across more than 650 ratings.
What we like:
- Designed for trial work
- Low frequency with a smooth tone
- Very well reviewed
Worth knowing:
- More expensive than the classic whistles
- Overkill for casual owners
Specifications:
- Type: pealess whistle
- Frequency: around 5200 Hz
- Colour: orange
- Brand: Acme
Acme 211.5 Alpha Whistle (Update 2023, Matte Black)
Best for: a modern, comfortable version of the popular 211.5
This is the latest update of the popular 211.5 from Acme, in a matte black finish and with a free whistle band. It has the same 5700 Hz note that made the original a favourite, in a slightly more comfortable shape.
The update makes it easy to hold in the mouth and to blow with light or firm breath, and the matte finish is less slippery in wet weather than the glossy original.
It costs around £12 and averages 4.7 out of 5 across more than 1,200 ratings, which is the best average in this comparison.
What we like:
- Best review average
- Comfortable to blow
- Includes a whistle band
Worth knowing:
- Very similar note to the classic 211.5
- Slightly newer, with fewer ratings than the original
Specifications:
- Type: pealess whistle
- Frequency: around 5700 Hz
- Finish: matte black
- Brand: Acme
Buying Guide: How to Choose the Best Dog Whistle
What to Look For
Look for a pealess whistle, which has no pea inside and therefore will not stick, freeze or clog with saliva. Choose one made from durable plastic or metal, with a comfortable mouthpiece, and a lanyard so you always have it to hand.
Sound matters. A whistle should be loud enough to carry but not so shrill that it is unpleasant. If you plan to use it regularly, choose one that is comfortable to blow, so you can give clear, controlled signals.
Types of Dog Whistle Explained
Pealess whistles are the standard choice and produce an audible note that people can hear as well as dogs. Ultrasonic or silent whistles are inaudible to most people and are adjustable, but they are less predictable at long range. Trial whistles are tuned lower and are designed for serious gundog work.
For most owners, a pealess whistle is the easiest and most reliable way to begin.
Choosing the Right Pitch
A higher pitch, such as the 210.5, is sharp and easy for many dogs to pick up, but it can be shrill. A lower pitch, such as the 211.5 or 212, carries well over distance and is gentler on the ears. Try one and see how your dog responds, and pick the note that feels comfortable for you both.
Whatever you choose, be consistent. Use the same note for the same command, and always reward a dog that comes back to you.
How Much Should You Spend?
You do not need to spend much. The classic Acme whistles cost around £10 to £12, the Pro Trialler is around £15 and the silent 535 is around £25 to £30. Paying more buys a specialist tool rather than a better everyday recall whistle.
Frequently asked questions
Do dog whistles hurt dogs?
Used sensibly, no. A pealess whistle is designed to be audible to dogs at a comfortable level. Avoid blowing hard right next to your dog’s ears, and never use a whistle as a punishment.
How do I train my dog to a whistle?
Start indoors. Blow the whistle briefly, then immediately give a treat. Repeat many times until your dog looks at you when they hear the note. Then practise in the garden, on a long line, and only later off the lead in open spaces.
Which Acme whistle is best for recall?
For most owners, the 210.5 or the 211.5 is the best place to start. The 211.5 has a slightly lower note that carries further, while the 210.5 is sharper. Both are very well reviewed.
Are silent whistles better for barking?
A silent whistle is sometimes used to interrupt barking, but results vary. It is best used as part of training with rewards rather than a standalone fix. Consult a trainer if barking is a persistent problem.
Can I use a whistle with a deaf dog?
A deaf dog cannot hear a whistle, so it is not suitable. Use hand signals and a vibrating collar, if appropriate, and talk to a trainer experienced with deaf dogs.
Conclusion
For most owners, the Acme 211.5 Alpha is the best choice: it has the best review average, a comfortable shape and a note that carries well. The classic 210.5 and 211.5 are still excellent, well-proven whistles at a very low price, and either is a safe choice.
If you work gundogs or compete in trials, the Pro Trialler 212 is the specialist option, and the 535 is worth a look if you want a quiet, adjustable training whistle. Whichever you pick, take time to build the association with treats, and your whistle will become a powerful recall tool.
