My dog is a 9 month old male and we got him from the Humane Society. We have had for over a month and can't seem to get him to go #2 outside. And when we goes #2 in the house it is always the same place. We have changed his feeding so that after he eats we are there to take him out. Sometimes he will go outside, sometimes not. What can we do to get him to stop going #2 inside when he has no problem with going #1 outside? He has never went #1 in the house. Only #2. Help!
