The problem in your analysis is that you invert the chronological order of
the "groups". The group I is the newest, and IV is the oldest, according to
the article.
I think the study must be expanded to include many more breeds. Maybe each
breed of dog have so many "crossbreeding"in their origin that any breed can
be so many haplotypes. Maybe all haplotypes are very old and can be present
in almost all breeds.

Xolotzcuintl have haplotypes
D3 - shared with Border Terrier, Chow, Elkhound, English Setter, Fox
Terrier, Siberian Husky, Iceland Dog, Japanese Spitz, Whippet, Springer
Spaniel, Rottweiler, Poodle, Papillon
D6 - shared with Rumanian and Russian wolves, German Shepherd, Golden
Retriever, Basset, Bulldog, Belgian Groenendael, Afghanhound, Maremman,
Otterhound, Toy Poodle, Irish Water Spaniel and Tibetan Spaniel
D21 - only Xolotz
D26 - shared with Pug, Shar Pei and Ridgeback. (This can support an Asian
origin: pug and sharpei are Chinese and some books state that Rhodesian
Ridgeback was result of breeding between South African dogs and Phu-Quoc
Dog, brought by Englishmen from Thailand.
