I know what you mean about the oterh dogs not suiting you. I often go to adoption events and some days some nothing there interests me. Now, I don't mean nothing, but they are just not dogs I feel will fit in well at my house. Other days. I almost bring one home. the closest I cam was with Yugo, a dalmation, but we were soon going to be going on vacation. He was gone when I got back. Oh well, wasn't meant to be. If this puppy is meant to be yours, he will be there when you go back. He sounds wonderful!

You can change the name. Since the pup is young, he may not know his name yet. If he does, strat calling by both names, and then over time drop the first one. He won't realize you changed it
