I know EXACTLY what you mean! I have one yorkie now, and my husband was the one who approached me about getting a second one. Of course I got really really excited and said YES. We called the breeder from whom we got Hobbs and committed to getting another one from her, which we are supposed to bring home in early July. But now that the time is getting closer, I am getting so apprehensive. I just love Hobbs so much, and I don't want him to feel like I am replacing him in any way. Also, Hobbs is just so good and well behaved, that I am nervous about how bad the new puppy might be. But, after considering everything, I am getting more excited about getting her. We are going to visit her for the first time next week, and I know I am just going to fall in love when I see her. So, don't worry. How could you possibly not love another one?!
