I know how you feel. I lost my sweet poodle " Beau " a little over 4 years ago and sometimes I get to thinking about him and just cant help but cry. They touch our hearts so deeply that even after they pass on, they are really still with us. I think about him all the time and have one particular picture of him doing what he loved most in his little life, playing ball. It is in my bathroom where I get ready every morning and it just makes me start the day off happy! He was my sweet little angel and it makes me feel so good to know he is up there playing ball till his hearts content. He was 12. As others have said, another puppy will take over your heart so fast. You will never forget Twinkles at all, but you will find out you have so much love in your heart that you can share it with your new one. I really hope and pray that you are able to find a puppy that you can afford, or maybe a rescue? Good luck and Twinkles knows you think about her.
Twinkles looks so precious in those pics.
