This is a sad but heart-warming tale of a dog’s unrequited love for his master. It deals with what happens when his master gets sick.
In Sometimes Love is Under Your Foot, Colin Thompson sensitively introduces the idea that dads and mums sometimes get very sick.
It’s a bit over The Big Fella's head though, so he goes and grabs his current favourite, Where’s the Green Sheep? (written by Mem Fox and illustrated by Judy Horacek.) This is a modern Australian children’s classic that should be on every shelf.
