This is a short comic called "Ha sido un perro" (it's a dog) that was published in an anthology of (post)apocalyptic stories by "La Marca de Caín"
I did the script and art. It's traditional pencils and inks with the shading done digitally.
The story's name it's inspired on a speech line from the tv series "The Three Stooges" were one of the characters (Moe) says something like "The only honest man we found it's a dog". It has nothing to do with the story itself and it was named once it was finished but I always liked that line even if I didn't got it from the tv show itself but because it was used as an intro for a song by a rock band (Attaque 77) that I like. Just a little detail.
Also the dog's name (Mendieta) it's a little tribute to the great Fontanarosa.
