So i have a 13 week old GSD and I was trying to teach him how to bark are command. Nothing was working. i tried toys...i tried teasing him with treats...NOTHING WORKED. Until one day my wife was ironing and steam shot out of the iron...he started barking like crazy...He wanted to show the iron who was boss. So i started using the iron to train him...it worked like a charm. I thought you guys might appreciate this. I may develop a whole new training philosophy based on irons? maybe not.
