“Tobi was given to me by my husband while I was still in mourning for the loss of my boy Loki. He's a silly and mischievous boy whose ears aren't sure they want to stand up. Occasionally he chases his tail because he has an itch he can't reach lol. He's very loving though rotten and behaves when he decides to. He knows he's cute and uses it to get out of trouble. He's a clutz, but when he takes a tumble he tries to make it look like he meant to do that lol. He's also very smart.”

Health Summary

warn icon

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

ALT Activity

warn icon

Tobi inherited one copy of the variant we tested

Why is this important to your vet?

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

Tobi’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.

B41

Tobi’s Haplotype

Part of the large B1 haplogroup, this haplotype occurs most commonly in Lhasa Apsos. It’s a rare find!

Some other Embark dogs with this haplotype:

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

A1a

Tobi’s Haplogroup

Some of the wolves that became the original dogs in Central Asia around 15,000 years ago came from this long and distinguished line of male dogs. After domestication, they followed their humans from Asia to Europe and then didn't stop there. They took root in Europe, eventually becoming the dogs that founded the Vizsla breed 1,000 years ago. The Vizsla is a Central European hunting dog, and all male Vizslas descend from this line. During the Age of Exploration, like their owners, these pooches went by the philosophy, "Have sail, will travel!" From the windy plains of Patagonia to the snug and homey towns of the American Midwest, the beaches of a Pacific paradise, and the broad expanse of the Australian outback, these dogs followed their masters to the outposts of empires. Whether through good fortune or superior genetics, dogs from the A1a lineage traveled the globe and took root across the world. Now you find village dogs from this line frolicking on Polynesian beaches, hanging out in villages across the Americas, and scavenging throughout Old World settlements. You can also find this "prince of patrilineages" in breeds as different as German Shepherds, Golden Retrievers, Pugs, Border Collies, Scottish Terriers, and Irish Wolfhounds. No male wolf line has been as successful as the A1a line!

H1a.4

Tobi’s Haplotype

Part of the large A1a haplogroup, this haplotype occurs in village dogs in Colombia. It is common in small dogs like Dachshund, Miniature Dachshund, and Chihuahuas, but can also be found in larger breeds like Golden Retrievers.
