One suggestion...
If you cant be with the puppy every few hours crate training will not work. You seem to have a similar situation to mine, I work during the day sometimes more then 8 hours and cannot always come home in the day. I got a play pin for my little buddah. Keep it small at first just enough room for a bed area food and the wee-pad. you can start making it bigger after a few weeks or when he starts to get better about always going on the pad. This also helps while the puppy is not fully vaccinated because you cannot take him outside.
I have only had Buddah for 3 1/2 weeks and he uses his pad 100% of the time when in his playpin.
When he is out in the house with us I have pads in the room so he always knows where to go....being so small he has a hard time seeing over the furniture to find his play pen. I would say 85% of the time he makes it on the pad when he is not in his pen. pretty impressive for only 3 weeks.
