Try to Understand Me Snoopy and Woodstock

Blue background with burgundy text at the top and bottom. In the middle there is a black and white dog sitting, looking face to face with a yellow bird flying upside down with a speech bubble showing hash marks inside.

Snoopy is Charlie Brown's pet dog in the Peanuts comics by Charles M. Schulz. Though Snoopy's character was introduced in 1950, it was not until 1956 that the dog was illustrated as walking on its hind legs. Throughout the 1960s, Snoopy began to interact with yellow birds in the comics. In 1968, a particular yellow bird named Woodstock was identified as Snoopy's "buddy." Woodstock is consistently portrayed in the comics as having difficulty flying which can be used to explain why he is depicted upside down. Neither character is capable of speech. As such, they communicate through sounds and pantomime yet have no difficulty being understood by each other or other characters.
