ah I learning something new today. thanks for sharing this artwork!

Heh, your welcome, yay for art. It can be pretty, sexy, and educational, lol

For why... Not sure and at best we have vauge theories.

I do like scientific observations, always questions to be formed and the answer not always apparent, just statistics ^^

I found this summary. Maybe that answers your question.

Most snout actions are part of snout tenderness. Dogs nibble and lick each other. You see this behavior primarily between bonding partners. Dogs that live together, like each other or between dog friends.

Eee! Thank you Xaver ^^

Interested in where this goes next.

Well, we have seen Red get vored, Red with the wolf’s head, anything goes in this weird Red Ridinghood and Wolf multiverse/multi timeline I guess, lol

It's been said by many an expert that wolves etc. will try to sniff or lick inside a person's mouth because it's the most effective way (for them) to learn all about someone -- who they are, where they've been, what they last ate and how long ago, and God only knows what else they may want to know right away about you.

I've also seen the behavior referred to as a "muzzle greeting". Ergo, maybe we could interpret this as an invitation to do the same to themselves.

"Allow me to introduce myself." *GLOMF!*

And when they do it to someone who they've met before, that's equivalent to telling someone what they've been up to since.

I love this shipppppppppp
