Portrait of the Artist as a Young Dog is a collection of short prose stories written by Welsh poet Dylan Thomas, first published by Dent on 4 April 1940.

Written over a number of years, the often comic stories show glimpses of his life, from early childhood up to his teens as a young reporter for the South Wales Daily Post.

Ferris, reviewing it in The Times Literary Supplement said: "the atmosphere of schoolboy smut and practical jokes and poetry is evoked with lingering accuracy but with nothing more".

Critic Jacob Korg later commented that "taken as a group, [the stories] seem to trace the child's emergence from his domain of imagination and secret pleasures into an adult world where he observes suffering, pathos, and dignity".

[3] It has been suggested that few writers "have evoked as successfully the mysteries and adventures of boyhood, of young love with its shattered dreams... none has done it in as fresh and telling phrases, with an elation as natural and contagious".
