An apartment would not be a problem if you give your B plenty of exercise and nose time. Also, the office would be great, but do realise that dogs need a lot of sleep, not only puppies. Our 2 sisters (7 and 6) sleep all night and most of the day. So your B would need a quiet space in the office to retreat and sleep. Agree with eeeefarm: puppy time is extra intensive, but so much fun. Try to be with your B as much as possible. Enjoy!
