    He's a tired little man. 😴 #mamasboy

“Loki "Scruffy" lives up to his name.. now he's just Scruff or Sir Borks-a-lot because he is already about 72% naughty, depending on the day. He loves to get into trouble and gives zero 🦊 but is 100% a mamas boy and loves to snuggle (on his terms) . He came to us with his sister (Bella) on the coldest day of the year in a box.”

Through Scruffy’s mitochondrial DNA we can trace his mother’s ancestry back to where dogs and people first became friends. This map helps you visualize the routes that his ancestors took to your home. Their story is described below the map.

B1

Scruffy’s Haplogroup

B1 is the second most common maternal lineage in breeds of European or American origin. It is the female line of the majority of Golden Retrievers, Basset Hounds, and Shih Tzus, and about half of Beagles, Pekingese and Toy Poodles. This lineage is also somewhat common among village dogs that carry distinct ancestry from these breeds. We know this is a result of B1 dogs being common amongst the European dogs that their conquering owners brought around the world, because nowhere on earth is it a very common lineage in village dogs. It even enables us to trace the path of (human) colonization: Because most Bichons are B1 and Bichons are popular in Spanish culture, B1 is now fairly common among village dogs in Latin America.

B47

Scruffy’s Haplotype

Part of the large B1 haplogroup, we have spotted this haplotype in village dogs in South America, Africa, the Middle East, and South Asia. Among the 8 breeds we have sampled it in, this haplotype occurs most frequently in Newfoundlands, Australian Cattle Dogs, and Pembroke Welsh Corgis.

Some other Embark dogs with this haplotype:

The B1 haplogroup can be found in village dogs like the Peruvian Village Dog, pictured above.

B

Scruffy’s Haplogroup

B is a relatively rare paternal line that has only recently started to expand. The dominant lineage among the ancient Shih Tzu breed, it is also found among Tibetan Spaniels. Outside of these two breeds, B seems to be a particularly common paternal line among the village dogs of India and Southeast Asia, though it is found as far afield as Africa and down into Oceania. Considering that it is particularly diverse in northern India, it could be that this lineage hung out mostly in South Asia after the expansion of domestic dogs from Central Asia. Because it is present in Mongolia as well, it may not be surprising that ancient East Asian dog breeds are also part of this lineage. Alternatively, perhaps males representing this lineage headed north out of southern Eurasia, which eventually gave rise to the Shih Tzu and may have inspired stylistic representations of lions in ancient China!

H15.7

Scruffy’s Haplotype

Part of the B haplogroup, this haplotype has been found in village dogs in Qatar and India. Unlike most other haplotypes within the B haplogroup, we do see this in a select few breed dogs. Specifically, it occurs in the Shih Tzu and Tibetan Spaniel.

The B Haplogroup is most commonly found the adorable Shih Tzu breed.
