Well comparing Aussies I see online to her, their markings are very very different. They are more widely dispersed, broken up spots, not all crunched together like this. Plus, you would think being mixed with Aussie some of the pups in her litter would resemble Aussies more, except coloring and having blue eyes. Looking at the Aussies, most have white patches, they have VERY VERY long hair, and you would think at least one pup would be coated like an Aussie. They all remained short haired. Either way, I see nothing similar in Freckles and her siblings that would remind me of Aussie. The only reason I thought they were mixed when babies was because of the red merle pup in the litter. heh. The breeder emailed me back and this is what he said.
"Possibly a mix of Catahoula or Australian Cattle Dog.
No way to be sure.

Obvious no way to be sure, this is just a guess. Heard Australian Cattle Dog once before, but again she has none of their characteristics. So for now, I think it's safe to say she's a Catahoula/Llab mix. =)
