One of the most popular dog breeds in America, Canada and the UK is the Labrador Retriever. The Labrador makes a wonderful pet as the breed is generally considered friendly and well-balanced. With regular exercise, a healthy diet and lots of love, the Labrador can live to be 10-12 years old, although some are fortunate enough to reach 13 or 14. A common belief that 1 human year is equal to 7 dog years is not accurate, since dogs reach adulthood within the first two years of their life.
