New Canaan’s first K-9 Police dog in more than two years started his patrol on our nation’s birthday on Saturday, at the 35th annual Family Fourth celebration at Waveny. Apollo, a full-breed German Shepherd dog, has been with his partner, Officer David Rivera for 2.5 months, and lives with Rivera at his house. He is cross-trained as a patrol dog who also has a narcotics certification, the police officer said. Apollo will assist police in finding missing items, persons, and also locating narcotics. “His ability to find people, I would say, is the best tool that is going to be brought to the town,” said Officer Rivera.
