You might say that dogs were our first high-tech projects. As we co-evolved, we learned how to direct and develop dogs’ skills to benefit ourselves and to extend our reach. Fast-forward to the 21st century, and developments in technology are blasting at us at warp speed. From the basic (converting poo to power) to the jaw-dropping (growing bionic bone), technology holds a promise of better lives—not to mention some pretty cool gizmos—for us all. Here are a few highlights.
Start with a curious mind, add a dash of technology and what do you get?
Where there’s a problem, technology can often offer a fix, or at least an improvement.
Want to dress up a virtual dog, find an actual dog park or give your dog’s social life a boost? There’s an app for that … and for a whole lot more.
Another type of light is said to help SAD dogs—those who suffer from seasonal affective disorder . A new Portland based company  is creating light boxes similar to those used by humans; in fact, the founder was inspired by seeing how well his dog responded to the light box he used to treat his own insomnia. Taken in roughly 30-minute doses, the bright white light is thought to increase levels of serotonin and thus, a feeling of overall well being, which dogs seem to enjoy as much as we do.
Swabbing the Dog
Stem Cell Research In the field of regenerative medicine, which searches for innovative therapies that allow the body to repair and restore damaged or diseased tissues, stem cells offer one of the best hopes for success. Part of the body’s repair team, stem cells are unspecialized cells that can renew themselves and can sometimes become specific cells with special functions. In November of last year, the results of a trial conducted at the University of Cambridge showed spinal cord regeneration in dogs with severe spinal cord injuries (many of whom were Dachshunds). Thirty-four pet dogs took part in the trial; those who received a transplant of olfactory ensheathing cells— which came from their own noses—had significant improvements.

Low Tech: Historically, leather tanning was considered a smelly business, and no wonder. As one step in the process, dung—commonly, from dogs—was pounded into the hides, or they were soaked in large vats filled with a dung/water mixture. Those who collected the dung were called “pure finders.”
Robo-Dog: To give mechanical man Elektro  a companion at the 1939 World’s Fair, Westinghouse built Sparko, a robot dog that engineer Don Lee Hadley modeled on his own Scotty. After the fair, Electro and Sparko hit the road, making appearances in department stores and at theme parks.
Sticky Inspiration: A walk in the woods with his dog led Swiss electrical engineer George de Mestral to invent Velcro® (a combination of the words “velor” and “crochet”) in 1948. As he was removing burs from his dog’s coat, he noticed how they bound themselves to the fur. It wasn’t long before Velcro® rivaled zippers.
Natural Gas: It turns out that dog poo, the stuff we pick up and toss, is a useful—and a definitely renewable—resource. Placed in an airtight container, or “digester,” anaerobic bacteria break it down, converting it to biogas—primarily methane. At Cosmo Dog Park  in Gilbert, Ariz., a digester project run by students at Arizona State University’s College of Technology powers one of the park’s lights and reduces maintenance costs. It’s also lighting up the night in Cambridge, Mass., in Pacific Street Park , where conceptual artist Matthew Mazzotta’s “Project Park Spark ” keeps the flame burning in an old-fashioned park light using methane produced in a dual-tank digester. In both instances, the systems are themselves fueled by dog owners, who use biodegradable bags to pick up after their pups, then toss the bags in the digester: a perfect functional/technical mash-up.
Connectivity: A Mexico City Internet company recently tested a novel concept in 10 public parks: dog-walkers dropped full poop bags  into a special container that doubled as a router. For each pound of poop deposited, a set number of minutes of free wi-fi were available to all park users. Though it was conceived as a short-term publicity action, rewarding people for doing the right thing sounds like a winner to us.
Poop Power: Pet waste is a big deal, and a big business. An entire industry is devoted to removing it from yards, dog daycares, vet clinics and cities. Left uncollected, it’s a hazard not only to the unwary but also to the environment. To keep it out of landfills and waterways, some cities are taking the proactive approach of asking trash collection companies to apply technology to the problem. By developing strategies to convert poop to power, this oh-so-common waste material can be converted to a useful and environment- friendly fuel.
Sad Tech: In 1957, a Soviet mutt named Laika became the first animal to orbit the Earth, as well as the first to die in the process. A good-natured stray from the streets of Moscow, Laika became famous worldwide as “Muttnik.” Her demise was met with protest from around the world, and help propel the humane movement into the modern age.
Bad Tech: Snuppy, an Afghan Hound born in 2005, is credited with being the world’s first cloned dog, and Time labeled him the “most amazing invention of the year.” Commercial cloning of dogs has since become slightly more common, but is still a controversial use of the technology.
Weird Science: Using high-speed cameras and advanced mathematics, researchers have studied everything from how dogs shake themselves dry to how they figure out where to intercept a flung Frisbee. Thanks to their loose skin, wet dogs can shake off 70 percent of the water from their fur in four seconds; their backbones move only 30 degrees in either direction, but their skin can swing a full 90 degrees. Some of the things they discover may eventually find their way into use—such as automated cleaning techniques for the interiors of distant space rovers.
