Ultrasonic Bark Deterrent for Dogs 6 Months to 8

This device uses dual ultrasonic emitters to interrupt barking, biting and jumping through sound alone. It is intended for humane behaviour training and is not recommended for dogs with a history of seizures. The deterrent suits owners, joggers and delivery workers who want a non-contact way to manage excessive barking.

Effective Range and Frequency Limits

The unit operates up to 50 ft and offers fixed 25 kHz and variable 15 to 30 kHz frequencies with sound, beep and strobe options. It is not waterproof, so moisture must be avoided and storage should be indoors. Ultrasonic output may not affect every dog equally and comfort should be monitored during short sessions.

Simple Handheld Operation and Charging

A push-button design enables quick activation and a built-in LED light aids visibility during evening use. Recharging takes about three hours via the included USB-C cable and provides up to 30 days of regular use per charge. The lightweight housing fits in a pocket or bag for daily outings.

Questions about this item

Should I use the fixed 25 kHz setting or the variable 15 to 30 kHz range for my dog?

Start with the fixed 25 kHz tone for general training; switch to the variable 15 to 30 kHz range if your dog becomes accustomed to the single frequency or if ambient noise requires a different pitch.

How far away can the ultrasonic sound actually reach during a walk?

The dual emitters project sound up to 50 ft in open air; walls, wind and heavy foliage will reduce the effective distance, so keep the device pointed toward the dog for best results.

What does the USB-C port actually charge and how long does a full charge last?

The built-in battery recharges in about 3 hours via the included Type-C cable and powers the ultrasonic emitters, beep, strobe and LED light for up to 30 days of regular use per charge.
