I agree with you samrhett2. We do live in a high rise apartment and probably don't take him down and out enough to really get him tired out. No area around here for a dog park, that would be great. But when I do exercise him well, and he is tired, still, he wants to bark at the littlest noises. Lately he has started barking at the tv, even though before he was just fine with it. I hope it is a stage, otherwise I will eventually try the electronic collar with the beeper if not, then the shock. Have a great day
