The Week’s guide to what’s worth watching

Madonna of the Mills

Some 500,000 puppies sold in America each year originate in “puppy mills,” where dogs are bred for pet stores, often in inhumane and unsanitary conditions. Disturbing but ultimately uplifting, this documentary follows an animal-rights crusader from Staten Island, N.Y., on her one-woman campaign to rescue dogs from puppy mills in Lancaster County, Pa. It also follows the fates of several of the more than 2,000 dogs she has rescued. Monday, Aug. 29, at 11 a.m., HBO2
