When seeing this line art, I decided I was finally going to post a picture of all the puppies together and give them all names. So, let's start.
1) The gray-ish one with a slight blue tint is a female named Angel, as she is a complete sweet heart, obeys her parents, and is pretty much a goody-two shoes.
2) The black puppy with the silver paw and tail is another female named "Remedy", just because it's a pretty pet name.
3) The puppy with the blue tipped ears, blue paw, and silver tipped tail is a female named "Clarity" for being peaceful, caring, innocent, but playful.
4) The dark blue puppy is a male, who gained his father's blue trait (Even if Dark Rain is black with some blue) and his name is "Hurricane" as he is a wild pup who causes chaos, but can calm down in an instant.
5) The light blue puppy lying on him is yet another female, whose name is Aqua.
6) Last but not least, the white pup with the blue tipped ear, blue circle around his eye, and the black paw. It is the second male pup, and his name is December.
