Maggie and Silky and Joe by Amy Ehrlich
Joe and his cow dog Maggie are the best of friends, and they grow up together! One day, while Joe and an older Maggie are playing outside, a young, little red dog shows up, and Joe names him Silky. Maggie shows Silky the ropes and teaches him how to be the best companion to Joe. When Maggie dies, Joe and Silky both miss her tremendously. . .but they keep Maggie’s memory alive by playing and having fun, just like she always loved to do!
