Oh that is good news that she seems to be recovering.
Parvo is a horrible
virus, and easily caught. My dog had
Parvo when she was much much younger, and before she came to live with me. Mine also made a good recovery, and has gone on to be a very healthy dog, generally speaking.
It's great that she already has some appetite back. But be careful because the virus severely damages the gut lining, and even though she is fighting off the virus now, the damage will take some time to fully heal.
