Shock collars can be very effective in deterring bad pet behavior, but what if you could get the same results without hurting your beloved pet? The Spray Commander Remote Trainer uses a simple, lightweight, wireless remote control and a collar spray device to deliver adjustable bursts of stain-free, hypoallergenic citronella spray along with a tone reward, correcting your dog's bad behavior without pain. Spray Commander is made to correct common problem behaviors such as digging, stealing, trash raiding, chasing, and jumping. This harmless spray conditions your dog to behave properly by working on four of his five senses: he hears it, feels it, sees it and smells it.
