Snoopy's father is seen in the strip from Sunday June 18, 1989 , Father's Day of that year. He receives a Father's Day card with eight paw prints on it, which he says is signed by all eight of his offsprings (namely, Snoopy, Spike, Belle, Marbles, Andy, Olaf, Molly and Rover). He lives in Florida and is very fond of fishing and playing canasta.
Snoopy's mother is one of only two Peanuts characters to have first appeared in an animated television special before later appearing in the comic strip, (the other one being Snoopy's brother Andy). Snoopy's mother, named as Missy in the special, is seen in a flashback in Snoopy's Reunion, which was first televised on May 1, 1991. Her first appearance in the comic strip is in the strip from July 26, 1996, in which she travels on a World War I troopship to visit Spike, (in the infantry), who is ill.
Snoopy's father was added to the game Snoopy's Town Tale in September 2020 for the Peanuts 70th Anniversary event.
- In the TV special, Snoopy's Reunion, Snoopy's mother is given the name Missy, and in the iPad app Snoopy's Street Fair, his father is given the name Baxter. However, neither of these names have been given in strip, and therefore, cannot be considered canon.
