Awe! She sounds cute. <3 I love Shleties and American Eskimo dogs, better even because you have both in one. I call my dog several nicknames too, i call her Midget, since she's small and short legged. I call my other Jack russel, Zoe, Boo. Zoe responds to that nickname more than Baby, i don't call Baby nicknames as much, because her name sounds like a nickname. xD Baby is really agile and hyper, though most jack russels are. xD She's obsessed with playing fetch. One day we introduced her to a tennis ball, and she learned that when we throw it, and she brings it back, we'l throw it again. xD That's how she became so agile. It can be annoying though she wants to play it ALL day. She inherited this from her mom, who loved to play fetch too.
Her name is Baby. My older brothers kept calling her puppers, and i kept calling her Baby. And i WAS not gonna let her name be puppers. xD
My mom and myself were gonna call her Charity, but my brothers kept making fun of that name. Baby was just a name i'd call her every time i saw her, when she was young. It stuck. It's pretty handy she still looks like a puppy, or else the name wouldn't fit. xD She's one and half.
