Dib views GIR as an annoyance at best, and certainly doesn't see him as a threat to planet Earth; usually he just ignores the insane little robot in favor of exposing Zim. At times, he takes advantage of GIR's trusting nature to gain access to Zim's base, or to leave some spy equipment inside. Dib has also used GIR to contact the Tallest in The Frycook What Came from All That Space. GIR can be a nuisance to Dib, but unlike Zim, GIR doesn't seem like a hindrance to Dib. In fact, he ends up aiding Dib on occasion. In Zim Eats Waffles, GIR happily put the spy cameras in Zim's house to spy on him without question. Sometimes, Dib overestimates GIR's ability, such as in Battle of the Planets: GIR was sent to distract Dib, and after much button pressing, Dib simply asked GIR to go away, more out of exasperation than actually thinking it would work, and he seemed mildly surprised when he did. What Dib failed to realize was that GIR took his camera along with him, which held all his evidence.
GIR refers to Dib mainly as "The Big-Head Boy" although he does have various other nicknames for him. He treats Dib like he treats everyone else: with trust, kindness and a good dose of insanity. He claims in the unmade episode Return of Keef and aired episode Planet Jackers that he thinks Dib is nice. However, in the unfinished episode Mopiness of Doom when GIR desperately tried to get Dib to chase Zim again, it was made apparent that neither Dib nor GIR seemed to know each other's names; Dib only referred to GIR as "Zim's evil robot-dog-thingy," while GIR was seemingly content with calling Dib "Mary." Conversely, though, GIR previously showed knowledge of Dib's name in Planet Jackers. In Mysterious Mysteries, GIR also appeared as a surprise guest, and said he was upset that Dib was so mean to Zim.
Unlike Zim, GIR quite likes Dib, and didn't mind at all when Dib wanted to watch him contact the Tallest, even dancing with him after the robot had conveyed his message. Although Zim is his master, and GIR is occasionally shown to recognize that, he has no qualms with helping Dib in his plans to stop Zim (though this might just be that he doesn't understand what he's doing, or that he tends to be friendly with everyone he meets). GIR does not seem to think of Dib as an enemy. No one really seems to be an enemy to GIR, since he can't think about really if anyone's an ally or enemy. GIR also thinks Dib's head "smells like a puppy" while he was clinging to it in Tak: The Hideous New Girl.
