Does this make me a horrible person to think about other dogs when my dog died yesterday?

sweetie no, sometimes the very best way to cope with grief is to get another dog. this doesn't make you a bad person, as the love you feel for this dog will not erase the love you felt for your old dog. If anything, it will help bring to the surface memories of your dog that you may have forgotten. i'd even suggest getting another pom, because of the quirky personalities that they have, there is no law in the world that dictates the proper way to grieve, but crying and making yourself sick isn't healthy. the things we love most live on in our hearts, and smiling again and loving again in no way takes away from the memories you have of all the years you had together.
