Ralph and his mom love traveling together so much, and it would have been the perfect happy ending - but now, Ralph is sick.
Last October, Ralph developed a cough, and his vet wasn't sure why. "He was the picture of health and had never had any health problems before," Tomaru said. "It was hard to get an accurate diagnosis. It was finally through chest X-rays and EKGs that we found out he had the faulty mitral valve."
Ralph's condition is fairly rare, and can only be cured through specialized surgery. Medications have harmful side effects and can only prolong a dog's life, not cure the issue. The surgery is the only way to save Ralph's life, and unfortunately, it costs over $25,000.
But the cost hasn't deterred Ralph and his mom.
