Dog Keeps Opening and Closing Mouth: Understanding the Causes and Solutions

If your dog keeps opening and closing its mouth, you’re likely concerned about what’s causing this behavior. It can be a sign of anything from a simple annoyance to a serious medical condition. This article will explore the various reasons why a dog might repeatedly open and close its mouth, offering potential solutions and guidance on when to seek veterinary care. Understanding the underlying cause is crucial to ensuring your furry friend’s well-being.

Why Does My Dog Keep Opening and Closing Their Mouth?

There are several reasons why your dog might exhibit this behavior. Some are relatively benign, while others require immediate veterinary attention. Let’s delve into the possibilities:

Dental Issues:

Pain or discomfort in the mouth is a common culprit. This can be caused by a variety of dental problems, including:

Broken or chipped teeth: A fractured tooth can cause significant pain, leading to unusual mouth movements.
Periodontal disease: Gum inflammation and infection can make chewing and even closing the mouth painful.
Abscesses: These painful pockets of infection can form around the teeth or gums.
Foreign objects: Sometimes, a stick, piece of food, or other object can become lodged in the mouth, causing irritation.

Nausea or Gastrointestinal Upset:

Just like humans, dogs may experience nausea, which can manifest as excessive salivation and lip licking, often accompanied by opening and closing the mouth. Potential causes of nausea include:

Dietary indiscretion: Eating something they shouldn’t have, like spoiled food or garbage.
Motion sickness: Some dogs are prone to car sickness.
Gastrointestinal infections: Viruses or bacteria can cause vomiting and diarrhea, leading to nausea.
Bloat: This life-threatening condition requires immediate veterinary attention.

Neurological Problems:

In rare cases, repeated opening and closing of the mouth can be a sign of a neurological issue. These conditions require expert diagnosis and treatment:

Seizures: Unusual mouth movements can be a symptom of a seizure.
Facial nerve paralysis: Damage to the facial nerve can affect the muscles controlling the mouth.
Distemper: This viral disease can cause neurological symptoms, including jaw tremors.

Other Potential Causes:

Other less common reasons for this behavior include:

Oral tumors: While less frequent, growths in the mouth can cause discomfort and unusual mouth movements.
Allergies: Allergic reactions can sometimes cause swelling and irritation in the mouth.
Heatstroke: Panting excessively and opening and closing the mouth can be signs of heatstroke, a medical emergency.
