Saya: That is adorable! I had a dog once, even though not a pug, with similar intelligence. She would use it for mischief though :P
We in my family have always been soft, so our dogs are allowed on empty chairs at the table when we are not eating or when we are done eating. And this dog would then rest her head on the table if there were any leftovers there, and she would look all tired and in need of attention. Then she would drop her tongue out, seemingly at random and always hit the leftovers by "accident"
I love dogs
