There's a happy ending to a Jamaica Plain man's search for his missing dog-wolf hybrid. Taupaw, a Dutch Wolfhound, went missing Thursday night and, according to owner Alexander Humphreys, had been making tracks all over Boston and Brookline. Humphreys and the U.S. Coast Guard disagreed on whether or not it was Taupaw photographed on the ice of Quincy Bay. According to Missing Dogs Massachusetts, which had been publicizing Taupaw in an online poster, Boston Animal Control found the dog at a construction site in Dorchester. Humphreys filled Jamaica Plain News on the details of the reunion.
