We used it and worked good for a few days. Then our puppy started thinking it was a game. The trick is to do it once to get them to snap out of the thought. If you squirt, squirt, squirt they start to think it is a game. Good luck. We are now moving on to using compressed air as Mac doesn't respond at all to the squirt bottle. It isn't cruel and many people and trainers recommend it.
Thank you. I'll try it the next time.
How old is your puppy? I hope it's not going to be something he still does at 12 weeks or so :-\ ... come to think of it, they're still puppies until 18 months so looks as though it will be on going!
