Congrats on your new baby! She will be a beauty.
We've always given some time to naming our pets, watching their behavior and testing names.
One dog, we just couldn't figure out until I said to my husband, "she's just sweet as sugar". She looked up at me and, I swear, smiled. So Sugar it was and a perfect name.
Digger the rabbit loves to dig at the carpet.
Pouncer the cat.
Recued Mew from a shelter and he talked all the way home.
Squeak started as Lucky but he squeaked when he yawned.
My sister lived in Wyoming for years and goes with names like Saratoga (toga), Cheyenne, Shoshone (Shoni) Sundance and so forth.
Take your time, see what the pup responds to and have fun!
