Oh, God, Stacie, I'm so very, very sorry for your loss of little Harley. :flowers5:
He was a fortunate chinnie to have been discovered by you in that petstore. He came home with a Chin Mommy and Daddy who loved him and who knew how to care for him, especially having an emergency vet to whom they could turn in his time of need.
As painful as it has been for you and your chinnies, you should know that being with them as they passed was a great comfort to them, and being held and loved by their Mommy was the final bit of comfort that you could provide for them. As sad as it is, I think that it is still a good thing; I know that I would want to be held and loved and comforted by my mommy.
I'll keep you and all of your Chinnie Angels in my prayers.
