I had a trainer come to my home yesterday for puppy training and this is exactly what he has me doing when pup is doing something wrong I have to make a growl sound and spray her with a squirt bottle and stand up and it worked instantly! I was amazed at the results. it gets there attention and now its as if she looks for my permission to grab stuff. I have been working with her on not touching my stuff and seems like nothing worked until now. The trainer explained the whole theory of what we were doing and it all makes sense hope it continues to work.
