Yes, your dog, is probably an OMEGA dog. She could be licking you on the mouth in deference to your being the boss. Good thing HOWEVER - Brace yourself, dogs also lick on the mouth to try to get the ALPHA dog to give them some food. Your dog could just be hungry. Make sure you ALWAYS eat first BEFORE feeding the dogs, and ALWAYS feed the older dog before feeding the puppy, this just means putting down older dogs food bowl first and letting it eat a couple of chomps before putting the little ones bowl down. Pet the older dog first etc...Good luck with your pup, and Mr. Milan has some excellent tips on working with dogs.

Puppies lick the mouths of their elders to be fed. In the wild, adult pack members bring back food to the young by carrying it in their stomachs. Puppies greet returning hunters, lick their mouths, and the older dogs regurgitate the food for the puppies.

In domestic situations, this is a sign of respect and a greeting that begs you to reassure the younger dog that it is a good dog, that you are pleased with them. My two younger boy dogs always greeted Megan - the older and dominant one - by licking her mouth. Now that she is gone, I will sometimes put my mouth next to Casey's and mouth a 'MUM, MUM, mum" next to his lips. It somehow makes him feel confident.

Toby licks me on the nose, instead of the mouth. Maybe you can get her to lick there by ducking your head lower when she starts to lick.

When the dogs greet me like this, I will say to them, "No matter what, I am not going to puke up my lunch for you!"

Salt.
They like the taste of salty, food encrusted lips.

I Have the same situation - mine's a lip licker.I watch the behavior at the dog park - some dogs go up to other dogs in a very submissive position and give their lips a little lick. I bet it just means they respect the other dog. ( Or us )

Yes, I think that's what it is -- a sign of respect. She seems to do it when we're giving attention to her brother. If she hears us talking to her brother, she'll come running out and proceed to lick our mouths.
Not that she doesn't get attention. We made it a point to give her just as much attention. I think if she could talk while she's licking our mouths, she would be saying "hey, I love you too, don't forget about me".
We thought it had something to do with food in the beginning, as some of the posters mentioned.
But, believe me she's a little tank - loves to eat -- a one year old saint bernard who weighs 130 lbs! I think by the time she's two, she'll weigh the same as me! lol.
Hope she stops this as she gets older, though.
She's getting too big to be doing this. It's like she gets herself into a frenzy with this licking. Takes awhile to calm her down. It's annoying
Thank you, guys. Appreciate your feedback.

LOL... kissing is sweet but... I thing your dogs just consider you are the alpha dog. Color yourself lucky. Many people never get to that status.

My husband and myself strove for this position. Your dogs are saying to you that they think you are they boss. BTW, that makes your dogs RIPE for obedience training if you have not done so yet. Most people have to really work for that spot.

Consider yourself lucky, and simply tell them no if you don't like it. But do NOT give up the position they have obviously bestowed upon you. USE IT!

gag! hehehehehe! Just thinking about what my puppy has eaten, smelled and licked in the last 12 hours...no way would I let it anywhere near licking my mouth, let alone my face! LOL! I dunno why they do it, but I don't let mine lick my face.
Sorry, but it gives me the willies just thinking about it! lol!

My dog ALWAYS just wants to lick my mouth and my lips. My lips get chapped and he licks it. It's the only thing he wants to lick. I dunno. I would like to know too.
