that does help. I too want shakes to bark a couple times.... just not as much as he does. He is very protective of our house, and that is good.
The issue we run into is that he barks anytime someone approaches our porch. We live in the back half of a duplex, and share a walkway with the neighbors that live in the back half of the duplex next door. So he barks at them, and anyone visiting them, and as much as we socialize him to the neighbors, he still goes at it anytime they come and go. I am sure it is getting a bit annoying for them.
He was accidentally tested last week though. We left the front door open accidentally while getting ready to go for a picnic in the park, and the mail man came. He has to actually walk up onto the porch to put the mail in the mail box on our wall. Well Shakes ran right over to the doorway, and Barked and barked. I was worried the mailman would refuse to deliver mail again. But Shakes was really good and never left the house, he jsut stood right at the doorway and Barked. The mailman complimented us on how well trained he was, and we pretended that we had actually trained him to do that, when in reality he desided to be that disaplined all on his own!!!
