Lancaster gets another dose of “Lucky Dog” national spotlight this Saturday morning, but this time the focus is on rescued horses rather than canines. The Emmy-winning TV series, sponsored by Nutramax Laboratories, airs at 10 a.m. on CBS. A Lancaster employee of the company received one of the show’s rescued dogs in an episode that aired last month. This week’s show was taped last year at a local ranch, God’s Blessing Farm, where rescued horses are given a chance for a new life.
