Dug is the talking dog from the 2009 Disney/Pixar Film Up. He is known to have great tracking ability and can hear squirrels up to mile away. He is also prone to chasing balls and bringing them back and tends to fall in love at first sight with anybody who notices him.
Carl: "Did that dog just say 'hi there'?"
Dug: "Oh yes."
Dug: "My name is dug, I have just met you and I love you. My Master made me this collar. He is a good and smart master and he made me this collar so that I may speak. SQUIRREL!!"
