Why is my dog licking her lips and smacking her mouth often?

This sign could be quite generic and could be compatible commonly with teeth problems or nausea (related to gastrointestinal inflammation/infections), but it is not uncommon even in normal dogs. In Puffina case I would just monitor her should the signs be persistent or getting worse or should you notice any gastrointestinal sign as vomiting or diarrhoea. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Smacking her lips could be a sign of a dental problem or nausea. Diarrhea and throwing up can be caused by a food sensitivity, dietary indiscretion, intestinal parasites, an intestinal blockage, bacterial infection, viral infection, the weather, food change, stress, etc.  I would fast Kiwi for 24 hours and then put her on bland food for two days, such as boiled white rice and boiled white boneless chicken meat, fed in small quantities over several feeds and then transition back to regular food slowly over a few days. If this does not clear up the diarrhea or if the vomiting increases, or if your dog gets lethargic, she needs to see a veterinarian for an exam as there may be something more serious such as an infection going on.

Licking lips can be a sign of nausea in dogs, and that could be what's causing Fendi to do this behavior. Given that she is otherwise acting normal, I would monitor her for now. If she is still acting this way in the morning, or develops other symptoms such as vomiting and lethargy, I would have her seen by a vet.

This is usually a sign of nausea, which should be ideally checked as it could be compatible with a chronic type of inflammation. Considering her age, a physical examination and possibly more investigations (like an abdominal ultrasound of her abdomen) would be ideal.

Licking the lips can sometimes be a sign of nervousness, nausea, or even an issue with the teeth or mouth. If he hasn't had a dental cleaning recently, tartar on the teeth or gums could be causing some irritation and thus the licking behavior. Nausea such as from minor GI upset, may also cause drooling, or have signs such as vomiting or diarrhea, but this is not always the case. If it continues or you see any signs of illness/smell bad breath, etc, having your vet take a look is best. If you've changed something in his environment around the time the licking started (new pet, people, items in the house, etc) it could be that he's feeling a bit nervous or uncomfortable as well. Making sure he gets some extra attention and the cause of the nervousness is addressed (IE making sure he has someplace to go rest and hide, using a pheromone diffuser, etc) may help.

Chronic licking is a common sign of nausea, as well as hypersalivation. Nausea can be caused by many conditions such as dietary indiscretion (eating things Bella shouldn't be), intestinal parasites, foreign bodies, and pancreatitis. If Bella is consistently doing this, it is worth it to rule out the conditions above. Your vet may recommend bloodwork, x-rays, and possibly an abdominal ultrasound.

It sounds like Nene may be feeling a bit nauseated or anxious. This can cause symptoms such as burping/hiccuping, licking lips, drooling, etc. Causes can be anything from GI upset, to illness, bloat, or even something stuck in the mouth or throat. If he won't let you examine his mouth at all and is refusing to eat or drink, seems painful, or in distress, having him examined by a vet ASAP is best to rule out more serious issues.
