Oliver is now 5 mos old and he hasn't had an accident in the house in about 3 weeks now. He doesn't bark to let us know he has to go, he sort of goes to the back door, and stands there and gives me a look. I sort of know his schedule for pooping, so it hasn't been a problem. BUT about an hour ago I smelled something, walked in the den, and saw a pile of poop.!!!!...I freaked and yelled at him...He knew exactly why I was angry and he ran away from me, and was watching from behind a chair while I cleaned it up...He hung his head and has been lying on his favorite mat, chewing his chew, and very quiet...Did I do wrong by yelling at him and sort of pushing his nose in it? ( I actually didn't press his nose in it)...I am not sure what to do when this happens?...Thanks, Cheryl

thanks Jennifer, Ollie stares at me too, and usually goes toward the back door...I know the look, thats why I was so suprised when I found the pile...And yes he did slink around, and he was low, he knew what he did was wrong, I believe that...Today is another day, and a better day, no messes...
