I used to have a small brindle mixed breed named Sadie

I've learned over the years that dogs, like horses really do live up to their name sake. Soo pick carefully

For my german shepard I wanted something gentle, earthy, not too common and came up with a few then chose the one I liked best, Raine

She loves the water.. Mud, rain, all of it.. But she is very gentle and nurturing.

My rott, her name is Shadow, and she litterally does hide in the shadows

For your girl, being she's laid back and sweet with pretty green eyes, I'd go with something that's calming.
