Dog Parks are popular places to exercise dogs of all shapes and sizes. These parks are designed as a place where dogs can play off leash and interact with other dogs. The facilities are normally fully fenced, so your dogs can zoom around, stretch their legs, and as they are often large and unfettered environments they are a great place for you to work on your dogs social skills and basic training.
