Product benefits Precision training with one tool: Adjustable ultrasonic frequencies let you teach multiple commands (recall, attention, stop) by finding the tone your pet responds to best. Works at a distance: Effective up to 30 m, so you can use it in the yard, at the park, or in open spaces while keeping control from a distance. Portable and secure: Compact size plus the included lanyard makes it easy to carry. Special locking nuts and caps keep the whistle set and ready during active use. Suitable for dogs and cats: Designed to train both species using consistent, non-contact cues that support positive behavior reinforcement. How it solves common training problems Replaces inconsistent verbal cues: Different frequency settings help create clear, repeatable signals so your pet learns reliable responses. Reduces frustration and wasted time: Observe which frequencies elicit the best reactions and use the whistle until the desired behavior is established. Convenient for busy owners: Small and easy to carry, the whistle lets you maintain training continuity at home and away. Key features Adjustable ultrasonic frequencies for tailored training.
