Rex

Mixed Breed

“Rex was rescued from a kill shelter, then adopted by me one week later. He looks like a chow mix and has a spotty black tongue and a small lion-type mane. He is very sweet. He gives hugs that don't end and is unaggressive, though he doesn't seem to be scared of any other dogs or people. I've had him for two weeks and he only barked once when he was attacked. When given the chance to meet other dogs on his leash, he often rushes toward them quickly, but stops just as fast when he gets to them.”

Chow Chow Chow Chow
This distinctive-looking dog breed has a proud, independent spirit that some describe as catlike. Often aloof and suspicious of strangers, the Chow Chow may not be a cuddle buddy, but for the right person, they are a fiercely loyal companion.

Health Summary

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

ALT Activity

Rex inherited one copy of the variant we tested

Why is this important to your vet?

Rex has one copy of a variant associated with reduced ALT activity as measured on veterinary blood chemistry panels. Please inform your veterinarian that Rex has this genotype, as ALT is often used as an indicator of liver health and Rex is likely to have a lower than average resting ALT activity. As such, an increase in Rex’s 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.

Through Rex’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.

Haplogroup

A1d

Haplotype

A11a

Map

A1d

Rex’s Haplogroup

This female lineage can be traced back about 15,000 years to some of the original Central Asian wolves that were domesticated into modern dogs. The early females that represent this lineage were likely taken into Eurasia, where they spread rapidly. As a result, many modern breed and village dogs from the Americas, Africa, through Asia and down into Oceania belong to this group! This widespread lineage is not limited to a select few breeds, but the majority of Rottweilers, Afghan Hounds and Wirehaired Pointing Griffons belong to it. It is also the most common female lineage among Papillons, Samoyeds and Jack Russell Terriers. Considering its occurrence in breeds as diverse as Afghan Hounds and Samoyeds, some of this is likely ancient variation. But because of its presence in many modern European breeds, much of its diversity likely can be attributed to much more recent breeding.

A11a

Rex’s Haplotype

Part of the large A1d haplogroup, this common haplotype occurs in village dogs all over the world. Among the 23 breeds we have sampled it in, the most common occurrences include Rottweilers, English Setters, English Springer Spaniels, and wirehaired pointing griffons.

Some other Embark dogs with this haplotype:

The vast majority of Rottweilers have the A1d haplogroup.

Through Rex’s Y-chromosome we can trace his father’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.

Haplogroup

A2a

Haplotype

Hc.5

Map

A2a

Rex’s Haplogroup

A2a is a truly ancient lineage. Unlike the recent upstart A1 lineages which found their way from a few popular European males a couple hundred years ago into many dogs in many breeds, A2a shows ancient roots without major recent expansion. It is likely one of the oldest eastern Eurasian male lineages of dogs, where it has existed for thousands of years. Nowadays, it's commonly found in Tibetan Terriers and Chow Chows as well as in Southeastern Asian village dogs. The Chow Chow seems to have been depicted in sculpture over 2,000 years ago, so this is an ancient lineage indeed, and dogs with it have a long and noble pedigree! Males from this lineage have continued to be bred in similar forms and breeds for millennia.

Hc.5

Rex’s Haplotype

Part of the A2a haplogroup, this haplotype occurs most commonly in Chow Chows and village dogs from Papua New Guinea.

The large-sized Tibetan Mastiff descends from this ancient lineage.
