Wolf
He becomes really flustered. Like he doesn't know what to say at all, he never actually expected you to say any of this. Eventually he said 'you're welcome' then said that you are a really good partner to have as well, and that anyone would be lucky to have you.
Snake
His scaly face turned pink, really unable to know what to say. He just started into your eyes, he felt really appreciated, and then told you he just really loves you and wants you to feel just as appreciated and respected, and that he should be the one saying all that stuff.
