Leichman's conventional singsong ending (""So dream sweet dreams,/Your dog is near/ to guard you through the night./ Whoever said/ 'He's man's best friend'/ was absolutely right"") doesn't really spoil the fun provided by his brisk, frisky catalog of various members of canis familiaris: ""Frisky dogs and lazy dogs, risky dogs and crazy dogs, and snoopy dogs and sneezy dogs and snoopy, sneezy, droopy dogs. . . ."" Some dogs ""are even truly fond of beer,"" others ""wear galoshes in the snow,"" and we all know some ""who love a salty hand that they can take a lick at."" The matching drollery of the drawings, black line and wash on brown paper, might escape a story hour audience but will surely repay any dog-watcher's close-up attention.
