This is a tough one. My tendency has always been to lead with my heart, sort out everything else later. Not always the best route to take. The idea that you will have 5 acres is a very tempting "positive," although I agree that everything considered: The move itself, the stress of the move on everyone, getting settled, really starting a whole new family, are all factors to be considered. After you're settled, I'm sure adding another pup will be a lot easier. But, you have to do what you think is best for all of you. I tend to think, if I don't do it, adopt the poor litte soul who needs a home, no one will, and something terrible will happen. Hopefully Gracie will be adopted. I don't know whether going back to the shelter is a good thing or not. That might be very hard on you. If she's been adopted, I'm sure you will feel very relieved; if not, you will probably be more conflicted! Follow your heart, and pepper it with a little common sense! You're a good soul. I'll be rooting for you and Gracie and the best outcome for you both.
