REALITY Dogs in the City CBS, Global, 8 p.m. Bank on this series becoming a summer-TV perennial, if not part of CBS’s regular-season lineup. Since launching last month, the show has pulled healthy ratings, even opposite the Fox powerhouse So You Think You Can Dance. More to the point, the show’s star, Manhattan “dog guru” Justin Silver, is a good-looking dude with multiple tattoos, which can’t hurt his chances for primetime longevity. In tonight’s show, he takes a counselling session with the special-needs dog of workout king Russell Simmons’s executive assistant, Simone, who recently lost her eyesight. At the same time, Silver shows a family how their lack of discipline for their two bloodhounds has created petulant pooches, and provides some tough-love lessons for the owner of four rambunctious rescue dogs.
