if the potty patch intrests you they sell both the potty patch and ex pens at petco. There are others on here that have pictures of the set up they use,
Put down a shower curtain liner ( to prevent pee or poop on your floor)
use an excercise pen, put his crate in there, a bed, toys and pee pad, litter box or potty patch , this way he will most likely not use the bathroom where he sleeps, he will be able to get some excercise in and play while your gone to work and have a nice bed or crate or both to sleep in when he is resting? Just a thought!
