Here is my story...I've never really shared I don't think.
I found a local breeder and went to pick up a 7 wk. old puppy that weighed just about 1 lb. The poor little thing was the sweetest little puppy I had ever seen and I was TOTALLY in love from moment one. Even though she was NOT what a healthy Yorkie puppy should look like. She was a little homely. But, that just made me love her all the more. I was not planning on taking her to the vet for a few weeks. But, I thought maybe she had fleas and being a big bug hater, I had to take her the next day. So, I took her and found out that she had a really bad heart murmur.
I was SO sad. I cried so hard right then and there in the vets office. They all felt so bad for me. But, I couldn't even talk because I didn't want to cry more. In my heart I knew I had to take her back. We could only get one Yorkie and I just couldn't risk getting this one and having her pass soon. My goodness, we were so attached to her already, I couldn't imagine having her for a year or so and then having her pass. She was pretty sickly. We had a 3 day guarantee from the breeder (tell me she didn't know something was wrong!!) So I took her back that same day. It was one of the hardest things I have ever had to do.
Here is the important part though....she had something seriously wrong with her heart. She was sickly. If she only had something that could be treated with some meds, then there is no way I could have taken her back.
Whatever you decide will be right. If you keep this puppy you will wonder how you could have ever thought of giving her back....she will be the LOVE of your life. If you get a new puppy then that one will be the love of your life and you will be happy.
I still think about the first puppy and wonder about her. I felt so sad when I had to hand her back to the breeder. She kept looking at me like, what are you doing this for? It was SOOOOOOOOOO sad.
I will never forget her and I pray that she is o.k. If you LOVE this puppy, then I suggest you keep her. You won't be sorry. But, if you feel that you need to do otherwise, then you will be o.k. too. You will love the new puppy just as much.
(By the way, I went to visit my Sophie the same day I had to take back the other puppy. It helped with the grieving since I knew I had another puppy coming home in a few weeks. I went to a reputable breeder this time that I found on the AKC web page.)
BEST of luck to you. Please keep us posted....
