This is our newly found stray "Luna" . Can anyone tell me what kind of dog she is ... she is petite, and looks like she has a lot of Australian shepherd in her or maybe she is a full Aussie and just still a puppy. We are posting signs and trying to find her humans ...no collar, no tag , no chip.
She is so stunning. Dan named her Luna after Luna Lovegood from Harry Potter.

Microchip your pets people!!!
