I work full time...and I have four dogs. I usually work a 7 hr shift but sometimes I end up later its not uncommon for me to work an 8 hr day. Much longer than that would be pushing it though especially for a small dog they generally can't hold it as long. I do feel bad but well I love my dogs like they are my kids and I don't have the luxury of being able to stay home so I don't have a choice. I think they'd still be happier with me even though I work 5 days week then with somebody else. They don't seem to mind at all, and on the days I have off they pretty much just sleep all day. I definitely wouldn't get a puppy, my three huskies I had as pups but my job is a pet groomer so I took them to work with me a lot (every day when they were really young) so they wouldn't have to hold it that long. Not many jobs would let you do that.
