"What is an arthritic thirteen-year-old golden retriever to do when the human he loves most asks him to compete in a dance contest? Say yes, of course. Cosmo has been a devoted older brother to his human, Max, for a lifetime of trick-or-treating, movie watching, and family dance nights. And now Max is convinced that dance is the key to keeping his arguing parents--and his whole family--together. Max thinks that if he and Cosmo can win a canine freestyle competition (prize: a role in a movie!), Mom and Dad will remember all the good times they've had together and see that Max and Cosmo should never be separated. With help from veteran dog trainer Uncle Reggie, anxious Max and creaky Cosmo find a routine that is its own kind of unforgettable and discover that love can improvise its way around even the trickiest obstacles. Full of humor and heart, and told entirely from Cosmo's point of view, this is a rewarding exploration of human--and not-so-human--ideas of family, loyalty, and the most dogged kind of love."--
