The NHS and dogs; each keeps the nation’s heart beating. Trust Julia Donaldson, the rhymetastic author . . . to put the two together in a story that barks to our age. [P]aired with the supremely talented Sara Ogilvie . . . whose beautiful, humorous ink drawings match perfectly the bounding words. [T]he rhymes fly, the heart jumps. It’s guaranteed to give children and parents the literary equivalent of a giant welcome home wag. -- Alex O'Connell, Children's Book of the Week ― The Times

The verse skips along as cheerfully as Dot on her way round Wallaby Ward. -- Imogen Carter ― Observer

This is a truly wonderful book. The story is told in rhyming couplets which are delicious to read aloud and share with children. The bright illustrations are full of life, warmth, expression and tiny details that make this a wonderful book to come back to again and again. There’s always something new to see! The illustrations are inclusive in terms of ethnicity and disability which make this a brilliant book for all to read. ― BookTrust
