Breed type differentiation in Belgian Shepherd and Finnish Lapphund. Both the Belgian Shepherd (a) as well as the Finnish Lapphund (b) samples form discrete clusters in the MDS analysis. While there are established breed forms of the Belgian Shepherd, which – with some inconsistencies (see the Discussions) – correspond to the genetic clusters discovered in the STRUCTURE analysis (c), the clustering of the Finnish Lapphund samples (d) correlate with the pedigree lineages preferred by breeders. Note that the most of the Lapphund, regardless of their pedigree, are used as companion dogs and the subpopulation names in the figure do not necessarily reflect their contemporary usage. The “herding background dogs” are descendants of original Sámi working dogs, whose breeding follows the rules set by their corresponding breed association
