When Javier and River help with the spring cattle drive, Riley feels like the rope in a tug-of-war between two dogs. She can't wait for summer vacation and the long-awaited visit to Nana's farm, where there's nothing to worry about besides relaxing and having fun with Nana.
But things never turn out the way Riley expects, and this summer is no different.
Join Riley and Mia as their adventures continue!
