We recently adopted a 6 week old Bichon X puppy. Her previous owners gave up on her. Our problem has been housetraining. She pee or poop outside no matter how long she is out. The only time she goes pee or poop is in those times when she is out of our sight (in the house) for 30 seconds or so. She's now going on 14 hours without a pee or poop. I'm sure if I let her wander the house for a minute, she'd poop and pee somewhere. I suspect her previous owners scolded her harshly for defecating in the house. (They really had no idea about dogs). We've even had her on hour long off-leash walks and not even a dribble.
What is our next step?
