Sheldon Maxwell

Mixed Breed

“He’s spirited but sweet. He is typically very reserved when he first meets people or other dogs. (He’s pretty scared of being scared.) He has a very short attention span and loves his moms! He can be very cuddly and gives generous “horse hugs”!”

Health Summary

Sheldon Maxwell inherited one variant that you should learn more about.

And one variant that you should tell your vet about.

Urate Kidney & Bladder Stones

Sheldon Maxwell inherited one copy of the variant we tested

What does this result mean?

This result does not impact your dog’s health. It could have consequences for siblings or other family members, and you should let them know if you are in contact with them.

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.


ALT Activity

Sheldon Maxwell inherited one copy of the variant we tested

Why is this important to your vet?

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

Haplogroup

A1d

Haplotype

A11a

Map

A1d

Sheldon Maxwell’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.

A11a

Sheldon Maxwell’s Haplotype

Part of the large A1d haplogroup, this common haplotype occurs in village dogs all over the world. Among the 23 breeds we have sampled it in, the most common occurrences include Rottweilers, English Setters, English Springer Spaniels, and wirehaired pointing griffons.

Some other Embark dogs with this haplotype:

The vast majority of Rottweilers have the A1d haplogroup.

Haplogroup

D

Haplotype

H10.1

Map

D

Sheldon Maxwell’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

Sheldon Maxwell’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.
