Has anyone here ever used the "sonic" systems to stop barking. Or even one of the "spray" collars? I refuse to do shock. Here is our problem, Ein was broken in a large house with a big back yard so barking wasn't a problem. He would only bark when the doorbell rang. Then we had to move across state to an appartment. We were on the top floor and he only barked when our single neighbor came home. Then he was told NO STOP Barking if he went on for to long, which was rare. Now we had to move again and this time we are on the bottom floor facing in a courtyard. Now he's barking and howling at every little noise outside, and we are both (me and ein) getting really stressed out. Verbal repramand is not working, the spray bottle just makes him run-hide & pee, and I can't be home all the time. Any advise? BTW he is 3 years old.
