The Inland Empire 66ers have partnered with Blue Buffalo to create the first ever dog park in Minor League Baseball. The dog park is open during their Bark in the Ballpark games and is over 50 feet long and 25 feet wide. There are two separate spaces for small and large dogs. Leashed dogs are welcome in the grass areas of the ballpark during Sunday games, and now they can stretch their legs off-leash at the dog park, too. Check their website for current schedule of Bark in the Ballpark games.
