Yup, Im a worker with 2 stay at home boys! They are a little over 3 years old and do good at home for the most part. I wish I did things a bit different during their 'growing up' stage, but overall they are good boys who know the routine at this point.
I highly recommend you keep your pup in an X-pen when you are at work, at least until he is housebroken and past the teething phase. My boys DESTROYED my kitchen and I didnt know about xpens back then. They chewed my cabinets, baseboards and even holes in the WALL!! An x-pen would have kept them from having access to those things.
These days they are fine when I leave in the morning for work, they know the drill, they get a treat, I put the radio on for them and off I go. But if I DARE come home and leave again they howl to the moon, its the saddest noise EVER! I hate going home and going back out immediately because of that. I try to do everything i need to do straight from work so I dont have to leave them again once I get home for the night.
