When the veterinarian told Thomas Neil Rodriguez that his beloved 15-year-old dog Poh was dying, the New York resident decided to make the most of their time left together with a cross-country adventure."I initially wanted to get him to the Pacific ocean," Rodriguez told ABC News . "I have always wanted him to swim."So beginning in March, Poh, Rodriguez and his fiancee began a 12,000-mile road trip from their home in New York City to Los Angeles. They stopped in 35 cities along the way, visiting landmarks like the Washington Monument, the Space Needle and even Walter White's home from the AMC TV show"He loved it, it was so healing for him," Rodriguez said. "It was like he was five years younger. He was walking with a lot of energy."Rodriguez created an Instagram account to document their travels and other pet owners have shared their messages of support for Poh and Rodriguez.Poh, a mixed-breed that Rodriguez adopted from an animal shelter in 1999, has been diagnosed with multiple health issues. Doctors aren't sure how much longer he will live, but Rodriguez has vowed to continue to celebrate the time they have left together."I am super blessed that I have actually gotten to do this," Rodriguez said. "People think I take care of Poh, but Poh takes care of me."
