Sonic Pet Training Aid — 4 Tones, No Shock, Actually Humane

Four different sound tones for teaching dogs and cats the behaviors you want — without shock, without fear, without any of the fallout that punishment-based training creates. Ergonomically designed for comfortable use, effective for obedience training, recall, and new skill development, and based on the science of positive reinforcement rather than aversion. Training that builds the relationship rather than straining it.
