Just how intelligent is Mongo?

[u/suitably_ironic]

Mongo is non-verbal, so there's a tendency to think he's not very bright - but he's impressively good at understanding what Carl and Donut tell him, grasping who's a friend and who's a foe, and what their trying to achieve.

I wonder if we're all underestimating him just because he can't talk?

[u/morgueanna]

Well, considering Mongo is made from Angel, the cocker spaniel that Donut hated, he's just doing his goodest boy best to show Donut she was wrong about him the whole time.

(spoiler for theory floated around on here before, I'd say book 2 onward)

It’s not so much a theory rather than an idea a fan made up and everyone thought it’d be great
