Kaleb Drew, 6, is held in check by his autism service dog, Chewey, as he tries to leave after he was told to wait on the deck at his home after attending a half day of school in Villa Grove, Ill. , on Friday, Aug. 21,2009. Like seeing-eye dogs for the blind, trained dogs are now being used to help autistic children deal with their disabilities. But some schools want to keep the animals out, and families are fighting back. AP Photo logo AP Photo 3 months ago
