Does anyone else’s dog licked their other dog to like a ridiculous amount?

I don’t know what it is, but my dogs love to kiss but considering one is like 5x bigger than the other he just gets the little ones face so gross. It sometimes just is the big one basically assaulting the other one. My mom thinks he might like his eye boogers but he also licks his ears so idk. The last photo is the culprit.
