Why Do Dogs Mouths Quiver After Licking?

Dogs are known for their adorable quirks, and one of them is the mouth quivering that often occurs after they lick something. But why do dogs mouths quiver after licking? This behaviour has puzzled dog owners and experts alike, but there are some possible explanations.

One theory as to why do dogs mouths quiver after licking to help dislodge any taste or texture residue left on their tongues. When dogs lick, their tongues and facial muscles work together to gather information about the substance they are licking.

This information is then sent to the brain, which helps the dog determine whether the substance is safe to eat or not. The mouth quivering that occurs after licking may be a way for dogs to clear their tongues of any remaining residue and prepare for the next taste or texture sensation.

Understanding Dog Behaviour

Dogs are fascinating creatures that have been domesticated for thousands of years. They have evolved alongside humans and have become our loyal companions. However, despite their close relationship with humans, dogs still exhibit many behaviours that are difficult for humans to understand. One such behaviour is the quivering of their mouths after licking.

Dogs have a highly developed sense of smell and taste, and they use their mouth to explore and interact.

Licking is a natural behaviour for dogs, and it serves many purposes, such as cleaning themselves, showing affection, and communicating.

When a dog licks something, it stimulates their salivary glands, and they produce saliva. Sometimes, this can lead to excessive drooling, which is a common behaviour in dogs. However, in some cases, dogs may also exhibit a quivering of their mouth after licking.

The quivering of a dog’s mouth after licking can be attributed to a sensory response resulting in muscle contraction. This quivering is initiated by the activation of the nervous system, which sends signals to the muscles in the mouth. It can be caused by a variety of factors, such as excitement, anticipation, or even feeling cold.

It is important to understand that every dog is unique, and behaviour can vary depending on breed, and individual personality.

Therefore, it is essential to observe and understand your dog’s behaviour to determine the cause of their mouth quivering.

By doing so, you can ensure that your dog is happy and healthy, and you can strengthen your bond.

The Science Behind Quivering

When dogs lick, their tongues and facial muscles work together to gather information about the substance they are licking. The quivering of their mouths after licking is a natural reaction that helps dislodge any residue left on their tongues. This behaviour is also seen in other animals like cats, horses, and cows.

The quivering of a dog’s mouth is caused by the contraction of their facial muscles around their mouth. These contractions are involuntary and can be triggered by various factors, including excitement, anxiety, and cold temperatures.

One of the reasons of why do dogs mouths quiver after licking is due to activation of their Jacobson’s organ.

This organ is located in the roof of their mouth and is responsible for detecting pheromones.

When a dog licks an object or another animal, they transfer the pheromones onto their tongue.

The quivering of their mouth helps to draw air over the tongue and into the Jacobson’s organ.

This allows the dog to analyse the pheromones and gather information about the object or animal they have licked.

In addition to detecting pheromones, the quivering of a dog’s mouth after licking can also help to remove any leftover food. This is especially important for dogs, as they do not have the ability to brush their teeth like humans do.

Overall, the quivering of a dog’s mouth after licking is a natural and instinctive behaviour that serves several purposes. While it may seem strange or concerning to some dog owners, it is generally harmless and nothing to worry about.

Licking and Its Effects

Dogs have a natural inclination to lick things, whether it’s their owners, themselves, or just random objects. While it may seem like a harmless behaviour, there are some effects that come with it. Here are some things to keep in mind:

Saliva Production

When a dog licks something, it stimulates the salivary glands in their mouth, causing an increase in saliva production. This can result in excessive drooling, which can be messy and unpleasant. Additionally, the excess saliva can cause some dogs to experience a “lip lick” or “mouth quiver” as they try to manage the excess saliva.

Taste and Texture

Dogs use their tongues to gather information about the things they lick. They have taste buds that allow them to detect different flavours and textures, which can help them determine if something is safe to eat or not. However, this can also lead to dogs licking things that they shouldn’t, such as toxic substances or objects that can cause injury.

Flehmen Response

Dogs have a unique behaviour called the Flehmen response, which involves curling back their upper lips and inhaling deeply after licking themselves. This behaviour helps them direct scents to a specialised organ in their mouths called Jacobson’s organ. While this behaviour is normal and not harmful, it can look strange to those who are unfamiliar with it.

Overall, licking is a natural behaviour for dogs, but it’s important to monitor their licking habits to ensure they are not putting themselves in danger or causing any harm.

Common Reasons for Quivering

Dogs can quiver their mouths for a variety of reasons, some of which are completely normal and harmless, while others may require medical attention. Here are some common reasons why dogs may quiver their mouths after licking:

Excitement or Anticipation

Dogs may quiver their mouths when they are excited or anticipating something. This can be anything from seeing their favourite toy to waiting for their owner to come home. The quivering is often accompanied by other signs of excitement, such as wagging tails and jumping up and down.

Cold or Nervousness

Dogs may also quiver their mouths when they are cold or nervous. This is a natural response to the body’s attempt to warm up or calm down. If the quivering is accompanied by shivering or trembling, it may be a sign that the dog is too cold or experiencing anxiety.

Oral Cavity Pain

One of the most common causes of teeth/jaw chattering in dogs is oral cavity pain or dental pain. A dog with a broken tooth, dental abscess, or gingival inflammation can be in pain, which manifests as jaw chattering. If you suspect that your dog is experiencing oral pain, it is important to take them to the vet for a check-up.

Endorphin Release

Dogs often show happiness and relaxation by quivering their mouth after licking, which is the result of endorphins’ release. This is a completely normal and harmless behaviour, and is often seen after a dog has been groomed or petted.

In summary, dogs may quiver their mouths for a variety of reasons, some of which are completely normal and harmless, while others may require medical attention. It is important to pay attention to your dog’s behaviour and take them to the vet if you suspect that something is wrong.

Health Implications

While quivering after licking is a common behaviour in dogs, it can also indicate underlying health issues. Here are some potential health implications of quivering after licking:

Dental Problems

Dental problems such as tooth decay or gum disease can cause pain and discomfort in a dog’s mouth, leading to excessive drooling and quivering after licking. If your dog’s quivering is accompanied by bad breath, bleeding gums, or difficulty eating, it is recommended to take them to a veterinarian for a dental check-up.

Neurological Disorders

Some neurological disorders such as epilepsy or tremors can cause a dog’s mouth to quiver after licking. If your dog has been diagnosed with a neurological disorder and is experiencing quivering after licking, it is recommended to consult with a veterinarian to determine the best course of treatment.

Anxiety and Stress

Anxiety and stress can also cause a dog’s mouth to quiver after licking. If your dog is exhibiting other signs of anxiety such as panting, pacing, or whining, it is recommended to consult with a veterinarian or a professional dog trainer to address the underlying cause and provide appropriate treatment.

Poisoning

In some cases, quivering after licking can be a sign of poisoning. If your dog has ingested a toxic substance such as chocolate, grapes, or certain household chemicals, it is important to seek emergency veterinary care immediately.

It is important to note that quivering after licking is not always a cause for concern and can be a normal behaviour in dogs. However, if the quivering is excessive or accompanied by other symptoms, it is recommended to consult with a veterinarian to rule out any potential health issues.

When to Consult a Vet

So why do dogs mouths quiver after licking? This can be accompanied by other symptoms, it may be time to consult a vet. Here are some signs to look out for:

  • Excessive drooling: If the dog is drooling excessively, it may indicate a problem with their mouth or throat. This could be due to an infection, injury, or foreign object lodged in their mouth or throat.
  • Difficulty eating or drinking: If the dog is having difficulty eating or drinking, it may be due to pain or discomfort in their mouth or throat. This could be due to an injury or infection.
  • Changes in behaviour: If the dog is acting differently than usual, it may be due to discomfort or pain. This could be due to a dental problem or infection.
  • Swelling or redness: If the dog’s mouth or tongue is swollen or red, it may indicate an infection or injury.

If any of these symptoms are present, it is important to consult a vet as soon as possible. The vet will be able to determine the cause of the symptoms and provide appropriate treatment.

It is also important to note that some dogs may have a condition called epilepsy, which can cause jaw chattering or mouth quivering. If a dog is experiencing seizures or other neurological symptoms, it is important to consult a vet immediately.

Overall, it is important to pay attention to a dog’s behaviour and any changes in their mouth or throat. If any symptoms are present, it is best to consult a vet to ensure the dog’s health and well-being.

Regular Veterinary Check-ups

Regular veterinary check-ups can help detect and treat any medical conditions that may cause mouth quivering in dogs. It is recommended to take dogs for check-ups at least once a year, and more frequently for senior dogs or dogs with pre-existing medical conditions.

Address Anxiety and Stress

Anxiety and stress can cause mouth quivering in dogs. Addressing anxiety and stress can help prevent mouth quivering. Some ways to address anxiety and stress in dogs include providing them with a safe and comfortable environment, using calming aids such as pheromone diffusers or calming music, and seeking professional help if necessary.

In conclusion, preventing mouth quivering in dogs can be challenging, but it is possible. Providing adequate exercise and stimulation, maintaining a healthy diet, regular veterinary check-ups, and addressing anxiety and stress are some ways to prevent mouth quivering in dogs.

Conclusion

In conclusion, dogs’ mouths quiver after licking due to a variety of reasons. It can be due to nervous system stimulation, tasting or savoring residual flavors, or even as a response to a particular smell.

While some dogs may quiver their jaws due to excitement or cold temperatures, it is essential to observe their behavior closely to determine if there is an underlying issue. If a dog is experiencing oral pain or discomfort, it may also cause their mouth to quiver after licking.

It is crucial for pet owners to pay attention to their dog’s behavior, as it can provide insight into their overall health and well-being. If a dog’s mouth quivering after licking is accompanied by other symptoms such as lethargy, loss of appetite, or vomiting, it is essential to seek veterinary care immediately.
