I keep Duke, 12weeks old, in a gated portion of my apartment during the day with his toys, food, water and pad. I get to come home for lunch so I can see how he's doing.
I've had him since he was 7 weeks old and he's been doing well with the pads when he pees. He still has trouble with going #2 on the pad though.
Everyone says that they're still too young for us to expect them to be trained, so I guess we'll just have to wait and be patient.
