my dog barks at everything and everbody outside I've tried both the citronella and the shock collar but neither one works, we have also tried using the spray bottle but that doesn't work either. The obedience instructor told us to shake a can of pennies but that just scared her half to death but she didn't stop barking and it all started when she was around 6 months old, we were watching a movie and we have surround sound and all of a sudden something happened to the speakers and thaey started cracking and it sounded like gunshots but extra loud Tango panicked when that happened and ever since then she has barked at everything. I think my dog is a fear barker is there a way to stop that without anything that makes a really loud noise? other than the barking she is the perfect dog for me.
