I'm the same, I have a Morkie too and I work 3 nights a week. he stays in his play pen (not crate) when I'm at work and I just leave out a pee pad for him in the corner. What I did find out though, is if i'm home too late...he gets bored or something and chews the living daylights out of the pad. So.....I started cordoning the playpen so he basically has enough room to fit his body in to get to the pee pad but no more than that....like a big V shape (don't know if you could picture that) but that has stopped chewing AND it has stopped him from peeing on the corner of the pad and making me wipe it up after a 14 hr shift.
