meh. I really feel that you should take some time to grieve for your poor puppy, and improve the life of your LIVING dog! Roxy is still living outside, is she not? Maybe use the extra effort and time you have to give Roxy extra special care, keep the house clean so that she can come inside, and spend lots of time exercising and training her. Why do you need a new puppy when the life of the dog you have now should be improved, you've admitted that yourself!
The fact that you jump from your puppy dying one day to thinking of names for your new puppy the next day really gives me a bad feeling. I have high doubts that the breeder you are buying your new puppy from is reputable... if they're calling them "teacup Poms", you bet they're a bad breeder! You really should learn from the unnecessary death of Tink, that it isn't WORTH the pain and trauma to the dog and your family to buy for a cheaper price from a crappy breeder/mill/broker.
