Hello, I was wondering if my puppy is purebred or if it's mixed as I can't find any ACD with its color and it kinda has a Border collies color pattern. I bought her off someone who bred them but I wasn't able to get one the normal coloring that the siblings had since she was the last of the litter left. I'm thinking because of the coloring as well. Not that it matters but I'm very curious. Then I see mixes with a slim face and stuff but my pup looks bulky, kinda like a baby pitbull in thickness from the head, mouth and all.
That's what I was kind of thinking. She has all the traits of a blue Heeler, from the stubbornness, to the nipping, to the trying to chase and nip at anything that runs. All her other siblings had all the regular markings a blue Heeler has which is the blue, brown, and white. She was the only one that came out with solid coloring.
