I was on the list for a male last year but the litter never took. I've spoken to the breeder who "discovered" the panda gene. She was pretty nice. They're pretty dogs. I'd like to have a panda some day but we'll see. I say "discovered" because she's the only one I've read who's had it documented at all.
Post away! Tell us also how you came about getting her. Panda's are still quite rare, so not many people have actually seen one in person. But we might be able to say if she might be a Panda, a regular GSD with weird markings, of maybe a mix? At any rate, I'm curious to see pics.
We adopted him as a puppy at Adoption Day at a local pet store. He is so beautiful and the most lovable dog I've ever known. When we adopted him, we were told he was a mix between a German Shepherd and Australian Shepherd, yet he was the ONLY one in the litter that looked SO different and had the blue eyes. I later started to think he may be part husky, because of the coat and eyes. After seeing the "Frankie" dogs picture, I thought surely he must be a Panda, they look IDENTICAL. I can get other pictures. I only had the ones posted on my work computer. I just don't know what angles are best to look for (like you mentioned the tail set and back end), so if someone could tell me, I will take pictures this evening and post them.
One of them was pulled by a breed rescue, and he was adopted by his foster mom. The other was adopted by a shelter volunteer before the rescue could pull him. Both were in kill shelters in the same geographic area--very likely bred by the same BYB (probably an amateur color breeder).
