Adjustable Ultrasonic Dog Whistle — Silent Bark Control, 2-Pack

Every dog hears the world a little differently. A fixed whistle is a guess.

One dog snaps to attention at a pitch another ignores completely. Off-the-shelf whistles pick their frequency at the factory and hope — which is fine, until your particular dog turns out to be unimpressed.

An adjustable whistle finds your dog's frequency. Slide it between audible and silent ultrasonic ranges until you hit the pitch that turns their head, then lock in your cue — for recall, attention, and interrupting the barking spiral.

• The pitch gets tuned to your actual dog, not a factory average
• Silent ranges reach your dog without serenading the whole street
• Works for dogs of all sizes, with 2 whistles and 2 lanyards so a backup always exists

Pair it with treats to build the meaning — a whistle interrupts barking, but only training replaces it with something better.
