Lucky for me Buddy is not a barker! BUT the lab we had before would bark all the time outside - some dogs are just more prone to bark and it can really get the neighbors MAD to say the least!
We soloved the problem by using a spray bottle of water and squirted her in the face when she barked and finally all I had to do was show her the spray bottle and she would stop barking. I also would say NO BARK when I corrected her. She did still bark when something was out of the norm ect.
