Has anyone seen that commercial for that little thing they have that emits some super sonic sound that gets dogs to quit barking? Do you think it works? I have a bichon that is really well behaved EXCEPT when she gets excited about going out, or coming in she cannot stop barking. She used to bark excessively at the mailman but after two years I think she is over that I let the dogs out at 5:15 am and don't like her barking like that and potentially bothering the neighbors. It also sometimes gets my other dogs riled up and then they start barking. Other training tips would be awesome.
