His name is "Rupee." His owner, Joanne Lefson, found him starved, dehydrated, and near death in a Himalayan region in Northern India.
She nursed him back to health and brought him along on her climb to the Mt. Everest base camp at more than 17,000 feet.
"It was quite amazing to watch Rupee transform into this amazing Mt. Everest trekking super dog," Lefson said. "He took the lead on most days. We were kind of dragging up behind him."
Another of Lefson's dogs, "Oscar," made headlines by becoming the first to travel around the world.
Oscar passed away in January after being hit by a truck in San Jose, but Lefson says she and Rupee climbed Everest together in Oscar's honor.
