Products include remote dog trainers that have the safest and most effective techniques to modify and shape the dogs behavior. We use tone, vibration and medical grade stimulation controlled via an ergonomic remote transmitter that allows immediate stimulus to the dog in training. 100 levels of stimulation conveniently adjustable by a rotary dial that can be locked to avoid over-stimulation.
