Carolina Dog

The Carolina Dog was originally a landrace, rediscovered as a wild dog by Dr. I. Lehr Brisbin, and originally documented in American dog breed publications in the 1920s. Although descended from free-ranging dogs, Carolina Dogs can make good family pets with proper socialization. Carolina Dogs have been a UKC-recognized breed since 1996 and are now part of the AKC Foundation Stock Service (FSS). While debates rage on about the genetic origins of the breed and whether there are still pockets of feral Carolina dogs living in Southeastern US, AKC and UKC Carolina Dogs clearly have a unique and identifiable genetic signature.

Health Summary

Rey inherited one variant that you should learn more about.

And one variant that you should tell your vet about.

Degenerative Myelopathy, DM

warn icon

Rey inherited one copy of the variant we tested

What does this result mean?

This variant should not impact Rey’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. Rey is unlikely to develop this condition due to this variant because she 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

Rey inherited one copy of the variant we tested

Why is this important to your vet?

Rey has one copy of a variant associated with reduced ALT activity as measured on veterinary blood chemistry panels. Please inform your veterinarian that Rey has this genotype, as ALT is often used as an indicator of liver health and Rey is likely to have a lower than average resting ALT activity. As such, an increase in Rey’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 Rey’s mitochondrial DNA we can trace her mother’s ancestry back to where dogs and people first became friends. This map helps you visualize the routes that her ancestors took to your home. Their story is described below the map.

A1d

Northstar's Rey of Sunshine’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.

A247

Northstar's Rey of Sunshine’s Haplotype

Part of the large A1d haplogroup, this common haplotype occurs in village dogs all over the world. Among the 32 breeds we have sampled it in, the most common occurrences include Boxers, Labrador Retrievers, and Papillons.

The vast majority of Rottweilers have the A1d haplogroup.

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