It's a journey that Luke Robinson and his two Great Pyrenees, Hudson and Murphy, set out on just three weeks ago.

"They wake up in the morning, they know when I'm breaking camp, they know when we're getting ready to go walking," Native Texan Luke Robinson said. "I'm just amazed at how excited, energetic, and happy they are. To them it's the perfect life."

But this is not your ordinary walk. Luke and his dogs, are hitting the road travelling from Austin to Boston raising money and awareness about cancer, particularly canine cancer.

Bone cancer took the life of Luke's dog Malcom just two years ago.

"Malcom was my boy. He wasn't my blood, but he was my boy," Robinson said. "My day rose and set with him, and it just devastated me."

Luke says he and his two dogs are now on a journey to rid the world of cancer, and they're doing it one step, one city, and one state at a time.

Making stops along the way to raise awareness, and to get the dogs checked out by the vet to make sure the journey isn't to much on their paws.

Although it's a long, hard journey, it's one that's touched the lives of others along the way.

"I am absolutely amazed," Robertson County Resident Zelta Sullivan said, as she watches the team walking along the highway. "I could cry because I'm so grateful."

More than eight months still lie ahead for the fearless trio. But Luke says whether he's walking the dogs, or the dogs are walking him, there's no one else he would rather share this experience with.

"After a long hard haul, at the end of the day there just the best mates anyone would want," Robinson said.

Throughout the journey, Luke Robinson will be wearing a T-shirt with the names of dogs affected by cancer to raise money for cancer prevention.

He also wears mementos of his late dog Malcom around his neck.

Veterinarians say as more and more dogs are living longer, the number of them contracting cancer is growing.

Caring for an animal with the disease can range from cheap, a couple of dollars a day for steroid treatments, up to about $15,000 for other treatments like surgery, or chemo therapy.

But doctors say research is the key to learning more about the disease.

"We're using exactly the same drugs and techniques they're using in people. So as advances come out in people, we can also use them for dogs and also dogs serve as a good model. "We can take what we learn from dogs and apply it to people too," Dr. Heather Wilson with the Texas A&M Small Animal Clinic said. "It goes both ways."

Doctors say the most common type of cancer in dogs is lymphoma, and although treatable it's not curable. When caught early, the dogs chances of doing better are drastically increased.
