Dog Smacking Lips In The Middle Of The Night (Possible Causes)
There could be a number out why your dog is smacking his lips in the middle of the night.
Lip-smacking in dogs is an instinctual behavior, but it could point to issues in other areas in his life.
A typical dog learns licking behaviors in puppyhood from their mothers. Their mothers usually lick them when they’re young so that urination and defecation can be stimulated. This is also her way of grooming them.
You will sometimes see dogs licking each other or dog licking humans. This is a normal part of their social interaction, and it can also be soothing to them.
Dogs are different from humans because they don’t have to explore the world with touch. They must rely on their tongues and noses to understand and learn their surroundings.
They have an acute sense of smell, and they tend to lick things that taste good or have a pungent smell.
Not only that, but they may also lick objects because they are bored stressed, or nervous.
However, licking may be a sign of something wrong with your dog and this is where you must pay close attention. Sometimes your dog may have an allergy that causes him to lick himself because he feels itchy.
Why Is My Dog Smacking His Lips?
Dogs frequently lick and smack their lips and this action is sometimes the way they communicate.
Sometimes they may be licking the drool that is dripping down from their face when they are in the presence of food. Or they lick their lips after they have just eaten and are satisfied.
Sometimes they may be licking their lips constantly to get rid of a disgusting taste. Dogs may also have a personal quirk where they lick their lips all the time and this is perfectly harmless. Dehydration is also another reason why your dog may be licking their lips constantly.
These are common reasons why your dog may be smacking his lips:
Your dog can have nausea for several reasons like eating too quickly or eating something toxic. If he has an upset stomach he can sometimes vomit so that the excess pressure on the abdomen can be alleviated.
Before vomiting takes place, there is sometimes saliva in the mouth. This saliva forms so that the throat and mouth can be protected from stomach acid that is brought up with the puke.
This can be the reason your dog smacks his lips. It is a physiological response from excess saliva that is accumulating in his mouth before he vomits.
If you think that your dog is about to vomit then you should get him to a place where it is better to do so like the bathroom when clean up is easier.
After the vomiting episode, you can provide clean cool water for your dog to drink. This will help to relieve some irritation going on in the stomach.
If your dog vomits only one and is okay after he has done this, and is not smacking his lips anymore, then you can consider the worst to be over.
However, if he continues to vomit then he should be taken to the veterinarian as soon as possible.
Sometimes hunger can cause nausea in your dog because gastric acid is accumulated in an empty stomach leading to fluid movement in the esophagus.
When this happens your dog has irritation in the mouth and throat causing him to lick his lips a lot. You may also see him swallowing and having hiccups.

Your dog may have a physiological reaction to the smell of food like meat cooking or opening a commercial dog food bag. Licking the lips is simply a way of not dribbling all over the place.
As the saliva pools in their mouth because of anticipation, he is likely to smack his lips and move his tongue laterally so that the saliva does not leave his mouth.
This reaction is totally normal and as long as you feed your dog you will notice that it stops.
Dr. Ivan Pavlov has conducted important studies on classical conditioning to show how dogs respond to stimuli. The research has been used over the years and is still used today.
He observed that dogs would begin to salivate as soon as they saw the people who usually feed them.
The dogs even recognize certain movements that are used when it comes to someone feeding them.
If you have ever been in a restaurant and saw your server coming out with the food you might automatically begin to salivate.

Just like human dogs make go through acid reflux especially when they are small breeds with high metabolisms. Gastric fluids usually go into the empty space when they have not eaten.
Then the intestinal fluids travel up into the esophagus from the summer leading to inflammation and irritation. Your dog will produce saliva and lick his lips to ease the irritation.
If your dog is healthy, then his sphincter muscle which is located at the bottom of the esophagus opening will be closed. This muscle stays closed so that fluids can’t enter the esophagus.
In smaller breeds and sometimes older dogs this muscle does not function properly and becomes loose. If this occurs then you need to take your dog to the veterinarian so that medication can be prescribed for acid reflux.
Object Embedded in Mouth
There may be sometimes objects embedded in your dog’s mouth causing him to lick constantly. Puppies and dogs in general typically like to sharpen their teeth by biting on stray objects.
