Find out how to do so with Lulu Flynn Shriftman's book by the same name. The animal lover will be at One Bal Harbour for the launch of her book as well as the hotel's new pet program, which will include a 24-7 "Pawcierge." GET IT: Enjoy pet grooming, t-shirts and other goodies tomorrow from noon-3 p.m. One Bal Harbour, 10295 Collins Ave., Miami Beach.
