Thanks so much for your messages. It is a comfort to know that others have had similar experiences with a positive outcome. I'm so glad I found this forum, everyone is so helpful and kind.
We have left the breeder a message to let her know what has happened. Hopefully its just a bug and she will bounce back. But it is such a worry. I have been reading about Parvo virus symptoms and worrying myself sick.
We have been to my parents' this afternoon and it was so strange coming home to her empty crate. My youngest daughter looked everywhere for her..
Thanks again and will keep you updated.
