The Innotek Spray Commander Remote Spray Trainer is in my opinion a safer more gentle way to train your dog. My dog is coming on 10 yrs old now and barks a lot for at times no apparent reason! The trainer has already help with some of the barking. My only concern is that when he is out say on the beach he likes to run and bark continuously, however when we press button 1 my dog goes a little sheepish and doesn't play as jolly as he does when the collar is not on!!
