For most dogs, a hike in the mountains is an enjoyable way to spend an afternoon. But for Tennille, a five-year-old black Labrador from North Carolina, it’s just another day at the office. While other dogs sniff the underbrush and splash through creeks, Tennille is hard at work keeping her owner on the trail, alerting him to obstacles and watching for dangerous wildlife.
If it sounds like Tennille’s hikes are no ordinary walks in the park, it’s because she’s a guide dog and her owner is a professional long-distance hiker who also happens to be blind.
Tennille’s story begins not on a trail in the mountains, but in the California home of Tasha Laubly, a volunteer puppy raiser. Laubly socialized Tennille, taught her basic manners and then, like many a proud parent before her, selflessly sent her baby off to school. That “school” was Guide Dogs for the Blind, and it was there that Tennille would meet Trevor Thomas and the course of her life would change forever.
In 2005, Thomas, a recent law school graduate and self-proclaimed adrenaline junkie, received the devastating news that a rare and incurable autoimmune condition was taking his sight. Eight months after that diagnosis, his vision had diminished to nothing.
To reclaim his independence, Thomas began long-distance hiking. Just 18 months after losing his vision, he became the first blind person to complete a solo thru-hike of the 2,190-mile-long Appalachian Trail, which runs from Georgia to Maine. And that was just the beginning.
Thomas began hiking trails all over the country and found that, while he could navigate the well-traveled Appalachian Trail by himself, if he wanted to take on more remote areas, having a partner was vital. When Thomas’s human hiking partner pulled out of a big hike at the last minute, he decided it was time to get a guide dog.
The search for the right dog and an organization that would work with him was arduous. While dogs have long been used to help the visually impaired regain their independence, training one for the trail was unheard of. When Thomas explained that he wanted a dog he could take on long, solo expeditions in the backcountry, most guide-dog schools balked. They were concerned that a guide dog would not be able to handle the sport’s mental and physical demands.
Then, he put in a call to Guide Dogs for the Blind in San Rafael, Calif., and found an organization that was willing to give him and his crazy idea a chance. When the trainers introduced Thomas to high-energy and exceptionally smart Tennille, the bond was instant, which was a good thing. Tennille was the only dog they had who might be able to meet the mental and physical demands of long-distance hiking.
Training a guide dog for backcountry work was unprecedented. There were questions about how she would physically handle the rigors of the trail, whether she could adapt to the unique demands of backcountry work and how she would transition between days on the trail and life in town. When it came to taking a guide dog into the backcountry, it seemed like there were more questions than answers. But Thomas, Tennille and her trainers were willing to give it a shot.
To be Thomas’s eyes on the trail, Tennille not only needed to master all of the skills required of guide dogs in the city but also, had to learn about life in the wild. She was trained to watch for low-hanging branches (she knows how tall Thomas is) and alert him to tripping hazards. If she decides that a situation is too dangerous, she will refuse to move forward. The Lab has also been trained to handle encounters with everything from rattlesnakes to moose, and knows how to look for trail signs and other landmarks.
“I’m the luckiest person around,” Thomas muses when talking about Tennille. “In a world of extraordinary animals, she is exceptional. She is a genius.”
In the three years since they became a team, Thomas and Tennille have covered more than 6,000 miles together, tackling trails all over the United States. With Tennille’s help, Thomas has completed solo hikes on remote, unpopulated trails that were out of his reach before she came along. Having a guide dog has been a game-changer for Thomas, who says that many hikers he meets on the trail don’t realize that he’s blind.
