is your dog licking his/her nose or just sticking their toungue out, s/he is thirsty or out of breath.
Many answers and all things that I have experienced with both my cat and my dogs in regard to your dog sticking its tongue in and out, my chow-golden retriever mix does that when you scratch an area he cannot reach on his own, my cat also does it very quickly (he is very large and is unable to groom his own back) so especially when brushing his back. The vet said it was normal and was out of their own reflex to groom and most times they don't even realize they are doing it. And will stop when you stop scratching in that area.
The dehydration is also something you will want to be very cautious of especially if they are wimpering alot too, and check the inside of the dogs mouth and make sure its gums and tongue are not white as this could be a sign of late stage heat stroke, their are other symptoms to watch for and you can find them on any Vet site..
I was wondering what type of dog you have because one other thing that could cause this is called "dirty mouth" Your vet can check for this. I have a miniature pinscher and recently I had him to the vet because he takes Rimadyl for his hip surgery that my previous vet did not do correctly so he still only uses 3 legs most of the time, anyway, while the vet had him in for bloodwork to make sure his liver enzyme levels were safe and stable, he noticed that my dog had dirty mouth, which is bacteria in the gums and causes infections. The antibiotics helped with some of the swelling which can be noticeable around the mouth but particularly under the lower jaw. If you notice a pouch that was not there before it is because the infection and gravity will cause the skin under the lower jaw to sag slightly. This was very prominent and noticeable in my dog because of his small size.
They will suggest surgery where they will use ultraviolet technology to clean your dogs teeth and extract any that are loose or decayed. Thankfully, my dog did not need any extractions so the cost of the teeth cleaning was much cheaper than anticipated. It is recommended that you brush your dogs teeth at least once every week or two. I do that diligently with all of my dogs now, but small dogs seem to have this problem and it also could be food stuck in their teeth so brushing truly does help keep their gums healthy. Despite what pet stores will tell you when they want you to buy the high price dental care treats for dogs. Hope this helps you out and let us know what you find out.
God Bless all of you who take the time to provide all of this useful advice. I have found everything from ideas to help my Siberian Husky who was afraid of thunderstorms to being able to prove to my husband that he feeds our dogs(kids) way too many treats and that they do not need to eat twice a day because they do not exercise enough to burn off that much food. You are all a great blessing to me. Thanks!1

It could be any number of things. He could be getting things stuck to the roof of his mouth. He may also be panting in his own very unique way. Dogs are not created equal. They each have their own distinct way of doing stuff. He may have something stuck in his teeth. Or, he could be just entertaining himself.
What you described isn't indicative of him trying to tell you something. If you're terribly worried I'd say go to the vet. He *might* have something medically wrong with him, though what you're describing doesn't sound like a disease to me.
Most likely it's just a quirk. It's not something to establish dominance, and it doesn't 'mean' anything other than it's something he likes to do.
Most of the time when my big dog does this is because we are scratching her in certain areas where it just feels good. She also does this sometimes when she scratches herself, behind the ear or one of her famous three -legged itches.....
Another reason for a dog sticking their tongue out... is dehydration.
It's called panting. Since dogs don't sweat, this is their way of cooling down.
Nuke him from orbit.
Just to make sure.
Panting to cool down, or maybe just licking its lips because it is thirsty.
