Attach the clip to the new pad. When your dog pees on the pad, the moisture alerts an internal sensor in the pad, which wirelessly transmits a signal to the treat dispenser. The treat dispenser then releases treats/kibble, rewarding your pet for using the pee pad correctly. An attractant in the pad encourages your pet to use the pad for easy training. Moisture is trapped in the super-absorbent bottom layer of the pad, leaving your floor clean and dry. Each pad can hold up to 3 cups of liquid. This effective and practical house-training tool teaches your pet where it's okay to use the bathroom, and it lets you continue your dog's potty training even when you're away.
