Its a warning to beware of deception; those who invite with a smile (and appearing friendly) but dont reveal their true nature.
there is a variation which simply says "show no teeth" as in give nothing away, not a snarl nor a smile.
Metaphor
Strip-ed
No not all snakes have fangs. Only snakes with Venom have the fangs, they use these to inject the venom. Snakes which kill their prey by constriction (squeezing) do not have fangs, they have rows of tiny teeth to grip there food as they swallow there prey.
Scientifically, there is no way to fully genetically merge a snake with a dog. If you mean in fantasy, what you would have would surely be an interesting creature. A snake can sometimes eat a dog, but that might not be what you mean.
I mean mutulism
It usually means that the snake is adjusting his jaw.... but if the snake is looking at you kind of lunged back, it could be a aggresive behavior
When a person smiles, but shows no teeth it is usually a "sneaky-shifty" smile. That can mean to be leary of that person. And, since people associate the Devil as shifty or sneaky, one presumes that is how Satan would smile. It is basically a folk saying.
A smile with teeth showing is generally seen as more genuine and indicates a higher level of comfort and happiness. However, it's important to consider the context and other body language cues to determine if someone likes you. Some people may simply feel more self-conscious about their smile and prefer to keep their mouth closed.
It means that either you have somethingstuck between your teeth and he thinks its funnyor he likes you.
Plenty of men smile with their teeth, it is polite. It could be that he is interested in you, or it could just be a friendly gesture.
If you mean "smiles" as a plural of "smile" then it would be "Osmehe" but if you mean it as a verb "smiles" as in "he/she smiles" it would be "smeje se".
yes,your teeth mostly chatter when you are cold. research shows that when you are cold your nerve system starts to act up causing you to shake and chatter your teeth

If she smiles then it's a YES. She just wasnt expecting it is all.
He's either laughing, smells a mare in heat or doesn't like you!!
cobras do not have teeth they have fangs (sometimes they are poisonous) *facepalm* ALL snakes have teeth, some have teeth AND fangs. NO snake has just fangs. And ALL cobras are venomous (you do not mean poisonous)! They are all Elapids (i.e. they are proteroglyphous). There's also opisthoglyphous (rear-fanged). This fits many Colubrids, such as the Boomslang, the Parrot snake, the Lyre snake, and MANY more. And there's solenoglyphous (vipers' delivery system) as well as aglyphous-no fangs (pythons, most colubrids, boids, etc.).
It means smiles
