Chihuahua

Chihuahuas have a huge personality that defies their tiny frame, known to be highly active and intelligent canines.

Pekingese

Pekingese were dogs bred for centuries to be the prized companions of the imperial family of China. Today they are still cherished family companions and show dogs who greet everyone they meet with dignity and grace.

Health Summary

danger icon

Chucho is at increased risk for one genetic health condition.

And inherited one variant that you should learn more about.

Intervertebral Disc Disease (Type I)

danger icon

Chucho inherited one copy of the variant we tested

How to interpret this result

Chucho has one copy of an FGF4 retrogene on chromosome 12. In some breeds such as Beagles, Cocker Spaniels, and Dachshunds (among others) this variant is found in nearly all dogs. While those breeds are known to have an elevated risk of IVDD, many dogs in those breeds never develop IVDD. For mixed breed dogs and purebreds of other breeds where this variant is not as common, risk for Type I IVDD is greater for individuals with this variant than for similar dogs.

What is Intervertebral Disc Disease (Type I)?

Type I Intervertebral Disc Disease (IVDD) is a back/spine issue that refers to a health condition affecting the discs that act as cushions between vertebrae. With Type I IVDD, affected dogs can have a disc event where it ruptures or herniates towards the spinal cord. This pressure on the spinal cord causes neurologic signs which can range from a wobbly gait to impairment of movement. Chondrodystrophy (CDDY) refers to the relative proportion between a dog’s legs and body, wherein the legs are shorter and the body longer. There are multiple different variants that can cause a markedly chondrodystrophic appearance as observed in Dachshunds and Corgis. However, this particular variant is the only one known to also increase the risk for IVDD.

Degenerative Myelopathy, DM

warn icon

Chucho inherited one copy of the variant we tested

What does this result mean?

This variant should not impact Chucho’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. Chucho 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.

Through Chucho’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.

A4

Chucho’s Haplogroup

The A4 maternal lineage is fairly rare. It is found in Cocker Spaniels, but A4 is also represented well among East Asian breeds including the Chinese Crested Dog, Shar-Pei and Shih Tzu. Moving away from Asia, it is also found among Chihuahuas (a very old breed!) and village dogs in Peru. This may be a lineage that moved into Western breeds because of their owners' tendencies to mix them up with Eastern breeds in the early modern period.

A208

Chucho’s Haplotype

Part of the small A4 haplogroup, this haplotype occurs in Chinese Crested dogs, Toy Fox Terriers, Miniature Pinschers, and village dogs in Mexico.

The popular Chihuahua breed descends from the A4 maternal line.

A1a

Chucho’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.7/H1a.8

Chucho’s Haplotype

Part of the large A1a haplogroup, this very common haplotype occurs in village dogs throughout the world (including southeast Asia, which is uncommon for A1a’s). Among the 25 breeds we see this haplotype in, it occurs most frequently in Labrador Retriever, Vizsla, and English Springer Spaniel.

Dogs with A1a lineage travelled during European Colonial times.
