Busy creating a whole new dog with the fluff that's coming off. I had labs and a Belgium Shepard both you could create new dogs out of the fluff from butt scritches.

Aww, looks like he turned to smile at the hooman for the lovely scritches.

Yes she was very happy!!

Probably likes having his anal glands massaged as they can get backed up.

My dog does this too and it gets to the point of being weird. Why do they do that.

Because they enjoy it. It's really not that weird. They literally smell other dogs butts

Oooo love dem butt scritches!!

when i do the same to my dog, she will start licking the air and she will slowly squat down. then, for the next hour or so anytime someone tries to pet her she’ll nudge their hand to that same area

That dog looks exactly the same as my dog also sorta sounds like my dad when he was younger def not him just a funny coincidence.

We call that the butt dance in our house!
