[Zeus is Loved]

Our baby, Perseus, is taking his poop in his house/bed. Zeus would sometimes bring it to us if we didn't find it fast enough to get a treat (which we thought was gross); however, taking it to the bed is REALLY gross. Any suggestions on how to stop it? Saying no and bad puppy are not cutting it. The weird thing is that he has not had one accident in our house. He goes potty (both) on the pads, and then he picks the poop up and takes it to his bed. Yuck!
