Dog breeds are identified by their specific characteristics and lineage, which are tracked through pedigrees. A pedigree is a documented family tree of a dog, tracing its ancestors back several generations.
It's possible that you're referring to a specific breeder or kennel known as "Johnson," but without further context, it's impossible to determine what you are asking.
Could you please clarify your question? For example, you could provide:
* The name of the specific breeder or kennel: "Are there any breeds of dogs bred by Johnson Kennels?"
* More information about the context: "I heard about a dog breed with Johnson bloodlines, what breed is that?"
With more information, I can help you find the information you are looking for.
