All You Need Is Love by Emma Chichester Clark (2019)
Plum the dog has lots of love in her life. She has her devoted mum and dad, and she’s got four best friends; Rocket, Esther, Bean and Jakey, who she always plays with in the park. But then one day, her friends invite some new dogs to join in. Plum isn’t so sure about them. Otto is very big; Bounder is elderly, and Milly is teeny-tiny. However, Plum soon learns that new and old friendships should be celebrated, and that there’s always room for more love in your life.
