Exercise is good for the body and the soul. Besides the physical benefits, it also gives you and your dog a chance to get out and enjoy each other’s company, and to socialize with like-minded pet lovers. Most dog parks are open during daylight hours all year long. At one new dog park in Biddeford, Maine, you can find four-legged friends frolicking in the mid-winter snows! So get outdoors and have fun, any time of year.
