Just curious, how old is the puppy? Our family raised puppies for Guiding Eyes for the Blind and I can imagine that this one isn't a baby baby puppy (8 weeks or so), so the worst of the potty training/getting up in the middle of the night is probably done. The older they are, the longer they can hold their bladders, which is nice.

I got a puppy (not for GEB, as a pet) at age 15, and I have to say that she & I bonded very thoroughly and she helped me through some of the tough times in high school. But it did make leaving for college harder. Luckily my mom isn't too much of a guilter and she loved the dog as much as me, so it was OK. Something to think about, though.
