Ultrasonic Dog Whistle – Adjustable Silent Training Whistle

Train calmly. Walk confidently. No shocks, ever.

This adjustable ultrasonic dog whistle gives you a clear, consistent signal your dog can hear from a distance but you barely can — the humane way to teach recall, quiet excessive barking, and curb unwanted behaviour.

Every dog hears a little differently, so the pitch is adjustable: turn the barrel, test, and settle on the frequency that makes your dog's ears perk up. Pair the sound with a treat every time, and you'll have a reliable recall cue within a few sessions.

Why it works

• Adjustable frequency — tune it to your dog's hearing for a response every time.
• Silent to most humans — train in the yard, the park, or an apartment without disturbing anyone.
• Humane & effective — no shocks or sprays, just a consistent cue you pair with rewards.
• Durable metal build — pocket-sized (5.3 cm), with a keyring so it lives on your leash or keys.
• Sold as a 2-pack — keep one on your keys and one in the treat pouch.
• Works at distance — ideal for recall practice at the park or on trails.

Pairs perfectly with positive-reinforcement training. Backed by our 30-day Happy-Dog Guarantee. Delivery takes 10 to 20 business days, with tracking.
