Birdseed is Popeye's dog, that first appeared in the comic book Popeye in 1956. He was adopted by the sailor after a Spinachovian government incident involved the animal (in the story "The Dog Who Wore a Crown!"), upon which Birdseed stayed in the series as Popeye and Swee'Pea's pet. However, he was only featured during a brief period. Later, in 1963, he would be re-introduced on the comic strip Thimble Theatre.
Birdseed was created by Bud Sagendorf.
