For many of us, there is no better walking partner than a dog. The Tucson Botanical Gardens, 2150 N. Alvernon Way, has been celebrating animal/human friendships since June with the Dog Days of Summer. The garden has extended its offering of native plants and pleasant walking paths to our four-legged friends through Monday, Aug. 31. From 7 a.m. to 4:30 p.m. daily, and 5 to 8 p.m. on Twilight Thursdays, visitors can bring their leashed dog for a garden stroll. Dog admission is $3 and a $20 dog membership is available for unlimited visits and a membership ID for their collar. Regular human admission applies. Guests are asked to bring a leash, water and waste disposal bags. For more info, visit tucsonbotanical.org.
