Jeez, that's a tough one. If the pups are purebred, you could probably find a good home for yours if you were forced to give it away or sell it. But this sounds like you'll have 2 dogs to deal with (since you have the mother) and that makes it even worse. I had to give away a black male pup a few years ago, and althought he went to an excellent home, it still sucked. :depressed:
But if you're taking a year off, a lot can happen during that year. You might land a good job and bag dental school, or change your plans a couple of dozen times. Been there, done that.
Good luck, and I hope you get in to Pill Hill.
