Alice, are you the same person as Eman Tan - both your accounts are registered under similar emails? Did you lose another of your dog this time?
I have just created an automated Lost & Found listing service, and created an account for you in PetFinder under your yahoo email (the password should have been emailed to you). I've also created the lost pet under your account, which you can login to edit.
Your pet is currently displayed at the main page of PetFinder, and at this page:
