Do any of you let your snake 'interact' with other animals(besides their food!) ? If so, how's their reaction? Are any of them ''friendly''?

Last night, while showing a friend my ball python, our pug sitting nearby got super curious and sniffed at his tail for a while. We laughed as the snake seemed interested and nosed at her, flicking his tongue a little bit. The entire time, he wasn't tense and could easily leave and retreat back into my robe pocket. But to my surprise, after the pug began to sniff the snake's face, he did a bluff strike at her and just about scared her to death! It's the first time he's ever done even a bluff strike at ANYTHING besides his food!

So now I know, no more interactions between them, even if he two physically couldn't hurt one another. I'm curious, have any of you let your snakes be near other animals?
