Trait rows are three-level bands normalised from a registry's published scale, never scores. “Trainability” describes how readily a breed is said to respond to structured training, not intelligence. “Shedding” is not an allergy signal — no breed is hypoallergenic. A blank means the registry records nothing, which is not the same as the two breeds matching.
Why these two breeds
Each of these breeds is listed as related to the other on the American Kennel Club's own breed pages. FaunaHub compares pairs where that relationship is mutual, so the premise of the comparison comes from the registry rather than from FaunaHub.
