I went out to the bar last night with a friend and came home about 1:00 it had been a long week. i make it to my front door and my key hits the deadbolt, my puppy 6 months old go's off the chain down the steps and i physically heard him hit the door on his way down. opened the door said his name and he sat right down. He was barking as loud as a much bigger dog would have thought our friends rotweiller was on the other side of the door. but makes me feel good he did what he did, it woke the wife up (she was a lil miffed) but goes to show even the heinz 57 pups are good dogs.
