I've been using Pet Corrector spray for Bentley In The Company of Animals Pet Corrector Sprays | PetEdge.com
I have used the pennies in a can for all of my dogs but Bentley acted like it was a game (he's bull headed) so I bought this can and it's made a world of difference for us! It's just air that sounds a lil loud, just to get his attention and boy does it ever!
We've been working on our turns and heel while on walks and since I started with the can he's about 95% on walks now.
He was getting bad about meeting people on the street, he wanted to jump up to greet them, one short spray and he sits politely to greet. (of course I have taught him all these things before hand, the sound just reminds him)
I use it in the house too (it's always in my pocket). I felt we were using words too much with him, Bentley NO, Bentley Leave it, Bentley down, so now I don't say anything just one quick spray and he snaps to attention and stops doing what he was doing. It doesn't scare him nor hurt him because you don't spray at him just spray to make the noise.
He has started humping everything in sight but now I spray and he stops. I don't know how something so simple works but it does. I almost didn't buy it because I thought no way will that work. It was the best $5.00 I've ever spent.
In fact yesterday I ordered another small can for my pocket and a LARGE can for home
Good luck, you're such a good mommy!
