What Breed Are These Puppies?

I'd believe Australian Shepherd x Australian Cattle Dog. Australian Shepherds can come in blue or red merle, as well as black or red, with or without tan points and/or white markings. The blue or red speckle coloration of the Australian Cattle Dog is also a type of merle. So, all the different colors of the pups are perfectly plausible. I would wonder if any of the puppies are deaf, since that often accompanies the merle gene. Do they not have the parents?

Leorose- None of the puppies are deaf as far as I'm aware. The mother is a blue heeler and and the father is the aussie. I was worried about the white puppies but they said their hearing seems fine. It's strange how genetics works but it's interesting to see how different the puppies are!
