You'll feel great when you welcome him home and you'll hopefully be refreshed and able to enjoy the rest of the time with him more. Sounds like a good move to me, although I imagine it will be hard getting used to. I have a hard enough problem leaving the dog in the College kennel during the day, even though she gets lots of walks and fuss from the students and really seems to enjoy it. In fact, she was downright miserable when I wasn't working, cos she had to put up with me all day!
