SAN DIEGO (CBS 8) - Two veterans will travel across the country with their dogs over the next month to help veterans keep their pets.

The Marine and Army Ranger arrived at Camp Pendleton Thursday night and are hoping to get San Diegans involved.

The two dogs, Spanky and CT, saved the lives of their owners after they were injured during their deployment, and now they are on a mission to help other military families going through the same thing.

Marine veteran Dan Spangler has a hole in his hip from serving in Iraq, but he never imagined that eleven years later, his dog would redefine his life purpose.

"He's why I'm here," he said.

It is a 6,000 mile cross-country journey with Camp Pendleton serving as their half way point, but their journey has been anything but conventional.

"If I came into hardship and I had to give up Spanky, I don't know if I would be here today," said Spangler.

Dan is joined by Army Ranger Veteran Joe Trainor Jr.

Along they way compete strangers have offered rental cars, a place to stay, and food. They call it the power of dog, and they hope to change veterans' perspective, one vet at a time.

The two men started in North Carolina with only $50 in their pockets. Since then, they have raised over $20,000, and their goal is to raise more than $100,000.

They said the more they raise the more military families they can help.
