Genetic Breed Result

Boerboel

Bred as a farming dog in South Africa, this breed had to be tough to survive harsh conditions and predators. But these thick-necked protectors are generally calm, so long as they can get some exercise. They are known for being great with kids and families, but you should have a dominant personality or they may be taking you for a walk instead of the other way around.

Dogo Argentino

The Dogo Argentino, also known as the Argentine Mastiff, is a large, white, muscular dog that was developed in Argentina primarily for the purpose of big-game hunting, including wild boar; the breeder, Antonio Nores Martinez, also wanted a dog that would exhibit steadfast bravery and willingly protect its human companion.

Dogue de Bordeaux

The Dogue de Bordeaux is a massive slobber-producing machine. While the origin of these giants is unknown, they have served in nearly every working role imaginable. They make a great companion, but proper socialization from a young age is a must.

Health Summary

warn icon

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

ALT Activity

warn icon

Riggs inherited both copies of the variant we tested

Why is this important to your vet?

Riggs 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 Riggs's ALT activity above their current, healthy, ALT activity. As an increase above Riggs’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.

Through Riggs’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.

A1e

Majestic Hybrid Mastiffs Riggs’s Haplogroup

This female lineage likely stems from some of the original Central Asian wolves that were domesticated into modern dogs starting about 15,000 years ago. It seemed to be a fairly rare dog line for most of dog history until the past 300 years, when the lineage seemed to “explode” out and spread quickly. What really separates this group from the pack is its presence in Alaskan village dogs and Samoyeds. It is possible that this was an indigenous lineage brought to the Americas from Siberia when people were first starting to make that trip themselves! We see this lineage pop up in overwhelming numbers of Irish Wolfhounds, and it also occurs frequently in popular large breeds like Bernese Mountain Dogs, Saint Bernards and Great Danes. Shetland Sheepdogs are also common members of this maternal line, and we see it a lot in Boxers, too. Though it may be all mixed up with European dogs thanks to recent breeding events, its origins in the Americas makes it a very exciting lineage for sure!

A275

Majestic Hybrid Mastiffs Riggs’s Haplotype

Part of the large A1e haplogroup, this haplotype occurs most commonly in Neapolitan Mastiffs. It’s a rare find!

A2b

Majestic Hybrid Mastiffs Riggs’s Haplogroup

A2b appears to have split a few times in succession, which means that some of the Central Asian male ancestors of this lineage went their separate ways before their respective Y chromosomes made their rounds. There is not much diversity in this lineage, meaning that it has only begun to take off recently. Two iconic breeds, the Dachshund and Bloodhound, represent this lineage well. Over half of Rottweilers are A2b, as are the majority of Labrador Retrievers and Cavalier King Charles Spaniels. While A2a is restricted mostly to East Asia, this paternal line is also found among European breeds.

H3

Majestic Hybrid Mastiffs Riggs’s Haplotype

Part of the A2b haplogroup, this haplotype occurs most commonly in Cavalier King Charles Spaniels, Brittanys, Soft Coated Wheaten Terriers, and village dogs in Lebanon.

Some other Embark dogs with this haplotype:

A2b is found in the Daschund breed.
