1. What Does Lip Smacking in Dogs Mean?
Dogs often make a loud noise when their tongue and lips move rapidly. This behavior is called lip smacking. It might seem like your dog is licking the air or chewing something that is not there. This behavior is fairly common, and in the majority of cases, it is not harmful. Some of the reasons are as follows:
- A natural way to wet their mouth
- A sign of expectation (like waiting for food or treats)
- A technique to ease their anxiety or uncertainty
- A usual grooming habit just before sleep
Nevertheless, persistent or strange lip-smacking, especially at night, can, at times, indicate a medical or behavioral problem.
2. Why Dogs Smack Their Lips More at Night
Often dog owners will be the first to notice this habit become more pronounced after sunset. Let’s consider some potential reasons.
A. Relaxation Before Bed
Dogs, a creature with the same nature as humans, have their own bedtime rituals. A dog could be too tired to sleep and lip-smacking might be one of the ways he/she tries to calm down. It has been said that in humans, a sigh or even stretching can serve the same purpose.
B. Dry Mouth or Dehydration
Nighttime lip smacking might be a sign that your dog is suffering from dry mouth. Possible causes include:
- Not having enough water prior to bedtime
- Resting next to a heater or in an arid environment
- Mouth breathing while sleeping
What to do:
- Ensure that your canine has clean water accessible throughout the night.
- Use a humidifier to keep the air moist if your place is very dry.
C. Dental or Gum Problems
One of the primary reasons for continuous lip smacking is dental problems. During the night when your dog is less active, he may feel discomfort more acute. Possible issues are:
- Destruction of teeth, sometimes a cavity is formed
- Infection in gums
- Teeth broken or accidents in the mouth
- Overgrowth of plaque
Signs:
- Strong-smelling breath
- Salivation
- Mouthing
- Refusal to eat
If you notice these signs, make a dental appointment for your dog with the vet.
3. Medical Reasons for Lip Smacking at Night
In some cases, this trait can be associated with physical or health-related issues. Here are the potential reasons:
A. Nausea or Upset Stomach
Lip-smacking can be an indication of nausea in its initial stage. Besides this, dogs might also repetitively swallow or lick their lips to make the stomach acid less irritating.
Possible explanations:
- Eating too fast
- Digestive problems
- Empty stomach (especially prior to breakfast)
- Acid reflux
Advice: Offering a small snack before bedtime might stave off morning nausea in case your dog’s stomach gets empty during the night.
B. Acid Reflux (Gastroesophageal Reflux)
Acid reflux is one of the prevalent reasons of lip-smacking during the night. When a dog lies down, the stomach acid can migrate up which causes slight irritation. Dogs will often resort to licking or smacking their lips as a way to ease this situation.
Ways out:
- Feed your dog smaller meals more often.
- Do not feed right before sleeping.
- If your veterinarian recommends, keep their sleeping position slightly raised.
C. Dental Pain
Toothache or gum swelling can cause dogs to lick and move their lips excessively. Pain is more intense during the dog’s inactive time and also when the saliva flow is reduced in the night.
D. Oral Injuries or Foreign Objects
A piece of food, grass, or small object lodged in your dog’s mouth can cause the dog to lick or smack its lips regularly. Look in their mouth thoroughly or have the vet examine it.
E. Seizure or Neurological Disorders
Though rare, nighttime lip smacking can be a sign of mild seizures occurring before or after.
Other indications:
- Twitching at night
- Unexpected rigidity or shaking
- Inability to comprehend upon waking
Never hesitate to take your dog to the vet if you notice any neurological symptoms.
4. Behavioral Causes of Nighttime Lip Smacking
In case your vet rules out medical issues, the cause might be emotional or behavioral. Dogs communicate their feelings through body language and behaviors.
A. Stress or Anxiety
Nervous dogs often continuously lick or smack their lips. They might feel insecure at night when the surroundings are quiet or dark.
Possibilities:
- Outside loud noises
- Being away from their owner
- Change in sleeping place
- New pets or people in the house
Ways to help:
- Make a sleeping area that is calm and comfortable.
- Use scents that are familiar, like a blanket that smells like you.
- Turn on a nightlight if your dog is scared of the dark.
B. Boredom or Attention-Seeking
An ignored dog might develop repetitive actions to attract attention. Lip smacking can be one of those ways.
Advice:
- Ensure your dog gets enough exercise during the day.
- Devote a little time to bonding before going to bed.
- If it’s not health-related, don’t reward lip smacking with extra attention.
C. Conditioning or Habit
In some cases, lip smacking becomes a conditioned response.
5. Environmental Triggers
Shifts in the home environment even on a minor scale may trigger strange nighttime behavior.
Factors contributing to the environment:
- Temperature fluctuations: Cold air may lead to dry mouth or shivering.
- New sheets or odors: Dogs have a keen sense of smell and feel.
- Allergens: Dust and detergent on the dog’s bed can cause nose or mouth irritation.
Stable and comfortable living conditions mean no unnecessary lip smacking.
6. When Lip Smacking Is Normal
Occasional lip smacking is not a cause for concern. It can be absolutely instinctive if it is infrequent.
Regular situations:
- After a meal or drink
- Grooming
- Bedtime
- Nervous for a short period but calming
If your dog is otherwise normal, eating well, and sleeping soundly, the behavior is probably non-harmful.
7. When to Worry
Keep an eye on the situation if the behavior becomes frequent or is accompanied by other signs.
Some warning signs are:
- No desire to eat
- Throwing up or choking
- Salivating a lot
- Using paws to get to the mouth
- Moaning or showing discomfort
- Losing weight
- Unpleasant smell from the mouth
If you observe any of these, reach out to your vet without delay.
