Hairy Maclary from Donaldson's Dairy (board book)

A durable board book edition of the iconic first Hairy Maclary book, introducing Hairy Maclary from Donaldson's Dairy and his gang of friends.

Out of the gate
and off for a walk
went Hairy Maclary
from Donaldson's Dairy

Hairy Maclary's friends join him for a walk until, with a sudden yowl, a wail and a howl, they all run off.

What could have caused such a scatter of paws?
