Rocky

Mixed Ancestry

“Rocky was said to be a American bull dog mix. He was a very timid and cautious dog, even at a young age. We've noticed it's very hard for him to see or recognize familiar faces. He has a wonderful sense of smell and plays a game of hide and seek to find treat rewards. He is very good at fetching and retrieving. His favorite game is 'go get it' ball. He is very loving towards family members but is untrusting and fearful of new people. He must slowly be introduced to them, then he accepts them.”

Health Summary

warn icon

Rocky inherited one variant that you should learn more about.

And one variant that you should tell your vet about.

Degenerative Myelopathy, DM

warn icon

Rocky inherited one copy of the variant we tested

What does this result mean?

This variant should not impact Rocky’s health. This variant is inherited in an autosomal recessive manner, meaning that a dog needs two copies of the variant to show signs of this condition. Rocky is unlikely to develop this condition due to this variant because he only has one copy of the variant.

What is Degenerative Myelopathy, DM?

The dog equivalent of Amyotrophic Lateral Sclerosis, or Lou Gehrig’s disease, DM is a progressive degenerative disorder of the spinal cord. Because the nerves that control the hind limbs are the first to degenerate, the most common clinical signs are back muscle wasting and gait abnormalities.

ALT Activity

warn icon

Rocky inherited one copy of the variant we tested

Why is this important to your vet?

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

A1e

Haplotype

A233

Map

A1e

Rocky’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!

A233

Rocky’s Haplotype

Part of the large A1e haplogroup, we see this haplotype in village dogs across Central Africa through the Middle East and into South Asia. As for breeds, we see it in the highest frequency among Irish Wolfhounds, with some detections in Greyhounds, Posavac Hounds, and Beagles as well.

Irish Wolfhounds are a consistent carrier of A1e.

D

D

Rocky’s Haplogroup

The D paternal lineage is very common in well-known populations of dogs. Breeds belonging to the D lineage likely have direct male ancestors that can be traced all the way back to the origin of domestic dogs themselves! One popular breed that commonly sports a D lineage is the Boxer. Boxers were developed in the late 19th century from Mastiff dogs, so it is no surprise that D is well represented among Mastiffs, Bulldogs, as well as Terriers. Intriguingly, D is also found among Lhasa Apsos, an ancient Tibetan breed, and Afghan Hounds. While the presence of this lineage in Polynesia or the New World can be chalked up to interbreeding with European dogs brought during voyages of discovery or later settlement, D is also well represented among village dog populations in the Middle East and Africa. If the fact that we find dogs bearing a D lineage in the Middle East (not to mention the large amount of diversity among Middle Eastern D lineage males) is any indication of ancient residence in that region, then the presence among Oceanian village dogs is peculiar. Rather, it may be that D is part of a broader Eurasian group of ancient paternal lineages which disappeared from the eastern portion of its original range, persisting in the island of New Guinea as well as West Asia and Africa. With the rise of Mastiff breeds, the D lineage received a new life as it became common among many types of working dogs.

H10.1

Rocky’s Haplotype

Part of the D haplogroup, this widespread haplotype occurs frequently in Boxers, Chinese Shar-pei, Croatian Shepherds, and village dogs throughout the South Pacific and southeast Asia.

The D paternal lineage is common in Boxers.
