Dib views GIR as an annoyance at best, and certainly doesn't see him as a threat to the 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 a spy bug somewhere. Dib also used GIR to talk to the Tallest in The Frycook What Came From All That Space. GIR can be a nuisance to Dib, but like Zim, GIR doesn't seem like a hinderance to Dib. He actually helps Dib sometimes. In Zim Eats Waffles, GIR happily puts 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. When GIR was sent to distract Dib, after much button pressing, Dib simply asks GIR to go away, more out of exasperation than actually thinking it would work, and he seemed mildly surprised when he did. What he didn't realize is that GIR grabbed his video camera when he left.
GIRGIR 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 very clear that both of them did not even know each other's correct names. Dib referred to GIR as "Zim's Evil Dog Thingy," while GIR called Dib "Mary."
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.
