You'd figure she'd see him turning up the AC or at least reason that is why the AC was on so high. I mean she knows she's being treated like a pet and that the dog man wants more affection from her.

I mean if she felt she had to because she was that cold despite knowing it was to force her to snuggle, she could have snuggled to the friend.
Is there no blankets in the house? I remember seeing them sleeping under blankets.
