My niece used a squirt bottle to train a black lab, this puppy was the wildest puppy I had ever saw. When he would do something Samantha would squirt him and talk to him calmly. I first thought Samantha should take him back to the pound(I know that is really a bad thing to think, but my brother just had a tumor removed from his brain and we were afraid the puppy would knock him down)but this worked ! The dog is a big dog now, a great pet and part of their family. Good luck with yours.
