Shikoku

The Shikoku is a small dog that resembles a wolf. Named after the island of Shikoku in its native Japan, Shikokus are a part of a group of dogs called “primitive” breeds because of their traceable ancient origins. While all dogs are ancient in that they stem from the same wolves, primitive breeds are unique in that they have retained the same characteristics for thousands of years.

Health Summary

warn icon

Tomoko has one variant that you should let your vet know about.

ALT Activity

warn icon

Tomoko inherited both copies of the variant we tested

Why is this important to your vet?

Tomoko has two copies of a variant in the GPT gene and is likely to have a lower than average baseline ALT activity. ALT is a commonly used measure of liver health on routine veterinary blood chemistry panels. As such, your veterinarian may want to watch for changes in Tomoko's ALT activity above their current, healthy, ALT activity. As an increase above Tomoko’s baseline ALT activity could be evidence of liver damage, even if it is within normal limits by standard ALT reference ranges.

What is ALT Activity?

Alanine aminotransferase (ALT) is a clinical tool that can be used by veterinarians to better monitor liver health. This result is not associated with liver disease. ALT is one of several values veterinarians measure on routine blood work to evaluate the liver. It is a naturally occurring enzyme located in liver cells that helps break down protein. When the liver is damaged or inflamed, ALT is released into the bloodstream.

A1b

Tomoko’s Haplogroup

This female lineage was very likely one of the original lineages in the wolves that were first domesticated into dogs in Central Asia about 15,000 years ago. Since then, the lineage has been very successful and travelled the globe! Dogs from this group are found in ancient Bronze Age fossils in the Middle East and southern Europe. By the end of the Bronze Age, it became exceedingly common in Europe. These dogs later became many of the dogs that started some of today's most popular breeds, like German Shepherds, Pugs, Whippets, English Sheepdogs and Miniature Schnauzers. During the period of European colonization, the lineage became even more widespread as European dogs followed their owners to far-flung places like South America and Oceania. It's now found in many popular breeds as well as village dogs across the world!

Tomoko’s Haplotype

Part of the large A1b haplogroup, we see this haplotype in village dogs in over 25 countries across the world. We have detected this haplotype in lots of breeds, and it occurs most commonly in German Shepherd Dogs, Maltese, English Springer Spaniels, and English Setters.

A1b is the most common haplogroup found in German Shepherds.

The Paternal Haplotype reveals a dog’s deep ancestral lineage, stretching back thousands of years to the original domestication of dogs.

Are you looking for information on the breeds that Tomoko inherited from her mom and dad? Check out her breed breakdown and family tree.

Paternal Haplotype is determined by looking at a dog’s Y-chromosome—but not all dogs have Y-chromosomes!

Why can’t we show Paternal Haplotype results for female dogs?

All dogs have two sex chromosomes. Female dogs have two X-chromosomes (XX) and male dogs have one X-chromosome and one Y-chromosome (XY). When having offspring, female (XX) dogs always pass an X-chromosome to their puppy. Male (XY) dogs can pass either an X or a Y-chromosome—if the puppy receives an X-chromosome from its father then it will be a female (XX) puppy and if it receives a Y-chromosome then it will be a male (XY) puppy. As you can see, Y-chromosomes are passed down from a male dog only to its male offspring.

Since Tomoko is a female (XX) dog, she has no Y-chromosome for us to analyze and determine a paternal haplotype.
