The fifth book of the Mesaland Series tells the story of lovable, lumbering prairie dog Big Fat. The largest prairie dog on the mesa, he loves to eat tender green stems and delicious prickly pears. His mischievous neighbor Little Ugly teases Big Fat when he plumps down for a rest on cactus spines and pops up howling. But when Big Fat shows off a beautiful litter of puppies, Little Ugly joins Big Fat as he watches carefully for the dangerous coyote Three-Toes.

First published between 1943 and 1949 and now available again, the seven books in the Mesaland Series introduce a new generation of readers to the animals and plants of the great Southwest.
