Do your dogs do this?

Yup! It's sooo cute! I've had several dogs do this. It's so cute! Both my guys did it quite a bit as puppies.

Lady does it every once in a while, then the tip of her tongue gets dry and she spends a couple seconds licking to get rid of the dry tongue.

Titan used to do a lot as a pup but now not so much here's one of him doing it

I've seen Smokey do that sometimes, but not often. Maggie doesn't
but she does make little sucky sounds when she sleeps. Makes me chuckle
every time. Dreaming of her mommy probably.

Tikeyas used to do that ALL the time, mainly when she was sleeping, it was so cute .
I think its a husky thing I miss her ...

He's doing it in this picture. Mikey does this sometimes, but not often.

These pics are adorable.

My cats often do it, but not so much the dogs.
