Owning a dog is a serious responsibility that requires time, money, and attention. It takes 10-15 years to raise a dog, and costs include food, veterinary care, insurance, and exercise. However, responsible dog owners understand that the rewards of gaining a loyal, loving pet make the commitment worthwhile. Popular dog breeds include Labrador Retrievers, Yorkshire Terriers, German Shepherds, Golden Retrievers, Beagles, Boxers, Dachshunds, Poodles, Shih Tzus, and Bulldogs.
