Aw, Prince, I sympathize.
When we were first married, we really wanted a dog. We were living in a tiny apartment, and I was a grad student. We figured we could make it work, so we went to the shelter and found a great puppy - a shy, adorable chocolate lab mix - made an appointment for the adoption, and bought a book on raising a good puppy. We went home and read the book, and it just became more and more evident that there was no way we could responsibly adopt this dog. We wouldn't have the time to train her properly and give her enough exercise so she wouldn't tear up our apartment. I called the shelter back and just bawled and bawled on their answering machine that we didn't think we could adopt the dog. I was just so sad, and so worried that nobody would adopt her and they'd put her down. She was adorable and I'm sure someone stepped up, and every time a saw a pretty chocolate lab on the street, I thought "maybe that's Our Puppy." But years later, having gotten a dog we love, I know we made the right choice. And you're making the right choice now.
One thing you might look into is local rescue organizations that foster dogs until they can find homes - check out
www.petfinder.com, do a search for dogs similar to yours in your zip code, and see what comes up in terms of local pet rescue organizations. That might make your decision easier, and you might be able to rest better knowing that she won't be put down.
Best of luck
