* All dogs are the same species: All dogs are *Canis lupus familiaris*, meaning they are all members of the same species.
* Breeds are artificial categories: Dog breeds are created by humans through selective breeding. They're not natural groupings like species.
So, technically, every dog is a breed because they are all part of the *Canis lupus familiaris* species.
However, if you're thinking about common dog breeds, like Golden Retrievers or Poodles, then a "mixed breed" dog is not a specific recognized breed. Instead, it's a dog with ancestry from multiple recognized breeds.
