Scrooge would very happily kiss his dragon doggo on the head. SHE IS HIS BEST GIRL, YES SHE IS

Ben would definitely do a kiss on the cheek or maybe an Eskimo kiss. Saft means a lot to him, after all!

And Azmuth would do his "lean against your neck it's freaking cold shut up this isn't affection why are we standing under poison" deal

Scrooge would get all the excitable yips and tail wags over this and then the biggest wettest tongue licks

Saft and Ben dhdgfjdsk--....that is VERY sweet and he'd receive the same back of course.

And Azmuth either gets a soft pet or a gentle peck atop his head because teeny frog man, must be delicate with him.
