Opened in 2011, the beautiful two-acre Charter Doyle PetSafe Dog Park is situated within Charter Doyle Park in South Knoxville. Well-shaded by fully mature cedar trees, the dog park features separate sections for large and small dogs, a dog water fountain, and dog waste stations. Charter Doyle Greenway, which is a 0.4-mile loop encircling Charter Doyle Park, also connects to the dog park.
