I too would say pennies in a can. This only works if the dogs are in close proximity to you. ie, if they run to the fence far in the backyard and you shake your can of pennies, they will not bat and eyelash!
But if you are close, this will shut them up. It scars them. Negative reinforcement. In my experience, pennies in a can doesn't cure the barking, just stops it in the moment.
Good Luck! |
