Flipping Their Tongues Up Means They’re Sorry
When a dog feels he or she has done something wrong, they will apologize by sticking their tongue out and flipping their tongue up in apology. It’s clear to them that they’ve made a mistake and they’re sorry for it.
They may also try to put on an innocent face because they know their owners are suckers for their cute faces when they do this. Even if it’s something as simple as peeing on the floor, they’ll do it.
Stretching
Dogs, unlike humans, do not stretch only when they wake up from a nap or to stretch out their muscles. Stretching, on the other hand, can represent affection and love for someone.
When you get home and see your dog stretching, don’t assume they were sleeping. They’re expressing their joy at seeing you, so show them some love and affection in return.
