QuietShift™

No. Most ultrasonic devices use a single static frequency — and dogs habituate to it within days. Barkvee™ cycles through a range of 25,000Hz–40,000Hz frequencies so the sound is never the same twice. Your dog's brain can't predict it, which means it can't learn to ignore it. That's the difference between a device that works on day one and one that still works on day one hundred.

No. Barkvee™ emits sound only — no electrical current, no vibration, no spray. It works the same way a dog whistle does: by producing a frequency your dog notices but doesn't find painful. It's completely inaudible to most humans. Veterinarians have confirmed that ultrasonic frequencies in this range do not damage hearing or cause physical harm.

Barkvee™ works on your dog's neurological response to sound, not their personality. If your dog has functional hearing, the multi-frequency burst will interrupt their focus — regardless of breed, size, or how "stubborn" they seem. That said, we're honest: this is not suitable for deaf or severely hearing-impaired dogs.

No — and it's not designed to be. Barkvee™ is a training accelerator. It creates a micro-pause in the behavioural loop so your verbal cues can actually land. The included 14-Day Protocol walks you through pairing the device with positive reinforcement. Most owners find they barely need the device after 2–3 weeks because the verbal cue alone does the job.

That's actually the most common reason people find Barkvee™. If your previous device worked for a few days then stopped, it fell into the Single-Frequency Trap — your dog's brain adapted to a predictable, unchanging sound. Barkvee™ was specifically engineered to prevent that with multi-frequency cycling. Different technology, different result.

Yes. Ultrasonic devices are fully legal in all five of our markets: US, UK, Canada, Australia, and New Zealand. They are legally and functionally distinct from shock collars because they emit sound, not electrical current. No jurisdiction anywhere in the world has banned ultrasonic training devices.

Other dogs within the 15-metre range will hear it — which in multi-dog households can actually be a benefit, as one press often calms all dogs simultaneously. Cats are generally unaffected, though individual responses vary.

Any breed with functional hearing. Owner reports show strong results with Staffies, German Shepherds, Cattle Dogs, Huskies, Chihuahuas, terrier breeds, and mixed breeds. Beagles and hound breeds may require more consistent use due to their bred-in vocalisation drive. The included Breed-Specific Tips Sheet covers the most common breeds in detail.
