Grab Fido and head out to the Mendon Ponds Park for an amazing day out. The 2,500-acre park features a mixture of woodlands, ponds, and wetlands that you and your dog can explore together. Your leashed dog is more than welcome to join you in the park to get a good walk in, sniff around, and run on the miles of grass that the park offers. Pay attention to signage when you're at the park since there are a few areas that your pup isn't allowed in the park. The park also features hiking, fishing, a playground, kayaking, boating, and camping.
