Why Does My Dogs Bottom Jaw Quiver

Why does my dogs bottom jaw quiver? There can be various possible reasons for such a movement; some of them are:

Your Dog Is Too Excited or Afraid

It could simply be that your dog is experiencing an emotion on the extreme side of either spectrum, such as excitement or fear. 

A dog often expresses their emotions as honestly as possible; this can be seen when you bring your dog to dog daycare, at home, or are simply meeting them after long periods.

In the case of daycares or other places relatively strange to them, your dog will show fear, in which their mouth may quiver slightly as their body may go into a fight or flight mode by releasing adrenaline in their body due to stress from the fear. 

Your dog may quiver their mouth whenever they are too excited; this may happen if they meet you after your absence or go to a place they prefer.

Your Dog May Be Facing a Dental Issue

It could be possible that your dog has issues with their gums; just like humans, dogs can experience dental problems. This is especially apparent for dogs as they are often less hesitant to dip their mouths into unhygienic places.

It may also be possible that a dog’s gum is not getting enough care as required and hence is far too dirty, or there is an internal issue with the gums.

In such a case, a dog may quiver their bottom jaw as a sign of a dental problem, and it will be essential to take your dog to an animal vet.

The Weather Is Troubling Your Dog

Your Dog Might Be Having a Seizure

A seizure may sometimes also be accompanied by a loss of appetite for the dog, fatigue, and general lethargy.

If you notice these different symptoms, you must take your dog to a veterinarian as soon as possible, as a seizure can signify a severe underlying medical condition.

The Dog Has Gotten Old

Like it or not, while you may want your furry buddy to remain as young as you got them first, a dog will grow up just as humans do and may reach old age.

An older dog, in most cases, may exhibit a variety of symptoms related to old age, including quivering of the bottom jaw. Unfortunately, besides taking care of your dog, there is nothing you may do to stop the quivering.

The quivering of the bottom jaw for an older dog will be noticeable once they become 11-12 years old.

If your dog experiences jaw tremors, it’s essential to consult with a veterinarian to determine the underlying cause and appropriate treatment.

Can Dogs Move Their Lower Jaw?

Yes, dogs can move their lower jaw to chew, bite, and vocalize. They have a hinge joint on each side of their skull that allows for a wide range of motion in the jaw. However, certain health conditions or injuries may affect their ability to move their jaw correctly.

Why Do Dogs Bottom Jaw Tremble After Licking?

Dogs may tremble their bottom jaw after licking due to the release of endorphins, which can cause a pleasurable sensation.
