I need you to focus, and compare the following stories. One is a failed adoption ; by FCDS ; a dog named MOLLY ; returned to FCDS by the adoptive family and euthanized . The second is a failed adoption ; by FCDS ; a dog named PETUNIA; returned to FCDS by the adoptive family and euthanized . The third is a SUCCESSFUL Adoption by the Rescue group : Colony Cats and dogs Rescue . Who pulled a "Rescue only" dog named BUG; screened the potential adoption family; chosee the family to adopt after screening them; and BUG remains alive, living in the home with another dog, and was not returned quickly to FCDS , during the first days and weeks of the adoption challenges that arise when introduction of a shelter dog, to an existing home with another dog is handled properly.
