Pet Corrector is what I use as a distractor in training.. It admits a hiss sound like a prey protection. Works nicely at the dog park when two dogs are about to fight. I never leave home without it, always on my side when training
Clix Sound CD is fun and effective to desensitize your dog to sounds, I use it in my car when driving the dogs around. A must have for spooked doggies. This is one of my favorite tools in my trainer box. Start very low, then gradually up the volume in a safe inviroment where your dog is comfortable : )
