I sure wish I had been a lot more strict with Wallee...wow..he barks and whines to demand play...We have a balcony on the front of our house where we go outside to smoke. He comes out there and wants to bark at the birds..when we tell him NO Barking, he will first run over to me for me to pet him when he stops, but then will stand and "grumble" at the birds..He knows he isn't supposed to bark but will continually grumble. Out back, if there is a squirrel, I am pretty much screwed. I have tried the water bottle and he just runs away and keeps barking. I have a can of pet corrector which works great inside but outside when there are birds or squirrels he turns into a wild man..barking his head off. My neighbor next door is an alcoholic and he will yell out the window even though I am out there with Wallee trying to herd in back in the house when he won't stop barking. very very frustrating...
