Foghorn Leghorn is a pompous and self-important rooster who speaks with a Southern accent and is characterized by his recurring catchphrases, "That's a joke, son!", and "I say! I say!"
Barnyard Dawg is a big, dim-witted, and lazy bulldog who, in contrast to Foghorn's proud and polite nature, is usually seen as a rude, gluttonous, and antagonistic character who attempts to catch and eat Foghorn.
In most of their cartoons, Foghorn and Dawg are adversaries, with the rooster being the clever one who constantly outsmarts the dog. Their conflicts usually revolve around Foghorn trying to protect himself, his chicken coop, or his barnyard from Dawg's attempts to eat him or steal his food.
Despite their antagonistic relationship, Foghorn and Dawg have been known to display occasional moments of friendship or cooperation, especially when facing a common enemy or threat.
