Mixed Ancestry

“Me and my boss/friend haul cars all over. We're in SC on I-95 and see a dog on the side of the road. We rescued him. He was a bate dog they threw away after the other dogs chewed him up. Vet said he had about a week to live if we didn't save him. He was 29lbs and they said he's around a year old. He rarely barks. He also don't bite, growl, or lick annoyingly. He likes to whine though. In a month and 3 weeks we got him to 56lbs, he's now 61. He loves going to the dog park & stomach rubs.”

American Pit Bull Terrier

The American Pit Bull Terrier originated in the British Isles and descends from the Mastiff-type dogs introduced to England in antiquity. The breed was brought over to the United States by English immigrants in the 1800s, and quickly became one of the most popular and widespread breeds there.

Health Summary

warn icon

Lou inherited one variant that you should learn more about.

Urate Kidney & Bladder Stones

warn icon

Lou inherited one copy of the variant we tested

What does this result mean?

This variant should not impact Lou’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. Lou is unlikely to develop this condition due to this variant because he only has one copy of the variant.

Impact on Breeding

This result is also important if you decide to breed this dog - to produce the healthiest puppies we recommend genetic testing any potential mates for this condition.

What is Urate Kidney & Bladder Stones?

This condition causes kidney and bladder stones composed of urate. In most dogs, uric acid is converted to allantoin, an inert substance that is then excreted in the urine. Dogs with HUU have defects in the pathway that converts uric acid to allantoin. As such, uric acid builds up, crystallizes and forms urate stones in the kidney and bladder. Uric acid is an intermediate of purine metabolism. While hyperuricemia in other species (including humans) can lead to painful conditions such as gout, dogs do not develop systemic signs of hyperuricemia.

Through Lou’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.

A1d

Caribou Lou’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.

A248

Caribou Lou’s Haplotype

Part of the large A1d haplogroup, this haplotype has been detected in village dogs in French Polynesia and Colombia. Among breeds, it occurs in Jack Russell Terriers, Fox Terrier Wires, and Cocker Spaniels.

The vast majority of Rottweilers have the A1d haplogroup.

D

Caribou Lou’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/Hd.4

Caribou Lou’s Haplotype

Part of the D haplogroup, this haplotype occurs most frequently in mixed breed dogs.

The D paternal lineage is common in Boxers.
