Now in its second year, the free Paws on the Prairie festival opens Trinity River Audubon Center and the Great Trinity Forest to Dallas’s canine community. The event will let visitors explore the Blackland Prairie and Great Trinity Forest and its five miles of trails with their dogs, give opportunities to take home a new friend through pet adoptions, learn how you and your dog can help the environment, taste great food and get free doggie waste bags. Even those without dogs are invited to enjoy the day.
