According to this North Carolina News & Observer story, state resident Peter Maynard was living in Massachusetts in 2006, when his retriever, Clyde, started sneezing blood. The vet couldn't figure out what was wrong, and Maynard stayed home with his ailing dog while relatives brought him food. When he later moved to North Carolina, doctors there found a tumor in Clyde's nose and gave him a few months to live. But Maynard was willing to do whatever it took to help his dog, and had doctors administer a round of radiation. Clyde responded well to the treatment and seemed to pull through.
