Meet the Oldest Dog on Earth

This skull fossil was discovered in 1975, but only recently was it linked to modern-day canines.

In 1975, Russian archaeologists, in a cave in the Altai Mountains of Siberia, unearthed a 33,000-year-old fossil skull that resembled that of a wolf.

So they assumed it was that of a wolf. 

Turns out it's not a wolf. It's a dog. 

And so the Champagne corks are popping in at the Russian Academy of Sciences, which made the discovery, and especially in the office of Anna Druzhkova, who led the team. The results were published this week in the journal PLOS ONE. 

To come to the finding, according to an article at Smithsonian.com, the team "sequenced mitochondrial DNA taken from one of the skull’s teeth" and compared it "with samples from 70 different modern breeds of dog, along with 30 different wolf and four different coyote DNA samples."

What did they find? Dog -- 33,000-year-old dog. Specifically, the DNA shared the most characteristics with Tibetian Mastiffs, Newfoundlands, and Siberian Huskies. 

So, if you have one of those dogs, you just got cooler, thanks to Anna Druzhkova. 

However, this whole dating-modern-dogs thing has been endlessly troublesome -- and this finding doesn't really help things. 

"Scientists know that dogs evolved as a result of the domestication of wolves," says the article, "but the specific time and location of this domestication is still poorly understood -- and this discovery further complicates that picture." 

How so? "Dogs may have been domesticated from wolves multiple times, and this breed of Siberian dog may have actually gone extinct, rather than serving as an ancestor for modern dogs."

Okay, fine. It might not be First Dog. But this also mixes up where scientists believe domestication first occurred, as this finding points to the "geographic spread" of dogs throughout Asia and Europe. Previously, scientists believed domestication occurred in the Middle East or East Asia.

"This skull could force scientists to rethink their theories," says the article.  

This DNA analysis does, however, set the age of modern dogs at 33,000 years. Previous DNA analysis of a different finding put the date at 16,000 years ago. That always seemed a bit thin to us.

Disneyland: The Most Exhausting Place on Earth (When Training a Service Dog)

Kami Jewart and Kendall, her service pup in training, at Disneyland

Today we’re going to take a trip to Disneyland with guest blogger Kami Jewart, who has raised five service dogs and serves on the board of Power Paws Assistance Dogs, in Ariz. Kami is a dog-lover who is passionate about helping others gain their independence through the partnership with service dogs. If you like this story, you can find more like it in the book Partners With Paws: Service Dogs and the Lives They Change, edited by Kyla Duffy.

The happiest place on earth is even happier with a four-month-old Golden Retriever. An integral and fun part of the service dog training experience is taking a trip to Disneyland. Sights, sounds, smells, and millions of distractions await the service dog-in-training at a Disneyland Park. People are overjoyed when they see a service dog partaking in the Disney experience, and the park and staff welcome service dogs.

Training at Disneyland is unmatched, as the pup-in-training is permitted to go on most rides. They need to remain calm while getting spun around on the teacups, and they must rest quietly at their owner’s feet as they soar high above Neverland on Peter Pan’s Magic Journey. They don’t meet the height restrictions for Space Mountain or Indiana Jones, so they have to forego those rides. However, a disabled person in the theme park with a service dog can do something like the “baby swap,” where if there is more than one person in the party, one can ride the ride while the other waits with the dog, and then they switch. People with service dogs are advised to obtain a guest assistance card when they enter the park, which helps their Disneyland experience go as smoothly as possible.

Meeting the characters in costume is one of the important Disneyland experiences for a service dog. I didn’t even think about how “scary” a person in a costume could be until my pup, Kendall, tried to run away from Pluto.

Another experience I wasn’t prepared for was the popcorn. Part of my responsibility as a volunteer service dog trainer is to get my pup-in-training to the point where he or she will automatically ignore dropped food. Once a service dog is fully trained, he or she can be expected to not eat dropped food off the floor, but at four months old, Kendall’s “leave it” command was not yet perfected.

Now that you’re aware of my duties, take a moment to picture Disneyland and all the spilled popcorn… and then think of trying to keep a four-month-old Golden Retriever away from it. Kendall took this opportunity to lunge at every morsel of salty, buttery, popcorn goodness children had inadvertently dropped throughout the park. At least we didn’t have to buy Kendall any snacks!

A day at Disneyland is an exhausting experience for children and service dogs alike. Near the end of our visit, Kendall fell fast asleep while waiting in line for the Pirates of the Caribbean ride. When we finally got on the ride, Kendall obediently hopped into the boat and lay at my feet. I hadn’t been on the ride in years, so I wasn’t prepared for the entire experience. We went through the various scenes on the ride, and Kendall seemed to enjoy watching the animated pirates singing and dancing.
We were nearing the end when it happened. The boat inched up a hill and then released into a sizeable drop. Kendall had never before experienced freefall, but he sure knew the location of my lap. As the water poured in over the edge of the boat, a little wet Golden Retriever landed in my lap. Now he was comfortable, and I was soaked!

Kendall quickly recovered from the Pirates experience, splashing the other patrons as he happily wagged his soaking wet tail. We stayed to watch the parade, and Kendall couldn’t keep awake long enough to be scared of the costumes or fireworks. He just dozed in my husband’s lap as the colorful light show bid us farewell.

This guest post is an excerpt from the book, Partners With Paws: Service Dogs and the Lives They Change, a compilation of 50 stories that highlight the important role service dogs play in people’s lives. From both puppy raiser and service dog team perspectives, readers gain an intimate understanding of service dog training, service dog team matching, and the liberating impact service dogs have on people with both visible and non-visible disabilities.
