P.S. Shade I have no idea what their names are! Would you like to finally reveal the secret?
The names are from an Anime/Manga series I was obsessed with in middle/high school called Prétear. I had 8 pups to name(2 litters as you mentioned) and at the time was rather obsessed with theming litter names.
I love all the things you include in looking up petz histories.
