If you’re like me, you probably wondered what the heck your dog was up to every time he or she opened and closed their mouth. Is he trying to tell us something? Did he just eat something gross? Is he about to puke?

Turns out, there can be a number of reasons why your dog is opening and closing his mouth, some more serious than others.

In this article, we will outline the most common reasons dogs keep opening and closing their mouths, so read on to find out more.

1. He Has Something Caught in Their Throat and Is Trying to Dislodge It

One of the most common reasons dogs keep opening and closing their mouths is because they have something caught in their throat. This could be a piece of food, a toy, or even a bug.

If your dog is having trouble dislodging whatever is stuck in his throat, he may start to paw at his mouth or gag as he tries to get it out.

2. He Is Choking and Are Trying to Clear Their Airway

As mentioned before, one of the reasons dogs keep opening and closing their mouths is because they have something caught in their throat. When this object is blocking the airway, it can cause the dog to choke.

If your dog is choking, you may notice that he is making a high-pitched noise as he tries to breathe, and his chest may be expanding and contracting abnormally.

3. He Has a Dental Problem, Such As Periodontal Disease or Gingivitis

If your dog’s mouth is constantly open, it could be a sign that he is suffering from a dental problem.

Here is a list of some common dental problems in dogs:

Gum disease

Gum disease, also known as periodontal disease, is a common dental problem in dogs. It is caused by bacteria that collects in the dog’s gums, and it can lead to tooth loss and other health problems if not treated.

Symptoms of gum disease include bad breath, red and swollen gums, bleeding gums, and loose teeth.

Treatment for gum disease may include dog mouth wash, anti-inflammatory pain relief, Antibiotics, and Dental cleaning.

To prevent gum disease, make sure to brush your dog’s teeth regularly and give them dental chews. Healthy diets and chew toys can also help keep gum disease at bay.

Gingivitis

Gingivitis is It is a mild form of gum disease and is caused by plaque and bacteria that collects on the dog’s teeth. At this stage, the gums become inflamed but there is still no loss of bone or tissue.

Symptoms of gingivitis include red and inflamed gums, bad breath, and a change in gum color from pink to red or purple.

Gingivitis is usually treated by cleaning the dog’s teeth while he is under anesthesia. Once the gums have healed, you will need to keep a close eye on them and bring your dog in for dental cleanings regularly.

In addition, at-home oral care is important. Make sure to brush your dog’s teeth with a toothbrush and dog-specific toothpaste at least twice a week, and give them dental chews and treats to help keep their teeth clean.

Periodontitis

Periodontitis is a more serious form of gum disease that can occur when gingivitis is left untreated. In periodontitis, the damage is more severe and irreversible. It is not only the gums that are affected but the ligaments and bones around the teeth as well.

Small dog breeds are more prone to periodontitis than other breeds. This is because their teeth are more overcrowding than large dog breeds, meaning there is less space between the teeth and more opportunity for plaque and bacteria to build up.

Symptoms of periodontitis include bad breath, red and swollen gums, bleeding gums, loose teeth, discolored teeth, irritability, and a drop in appetite.

Treatment for periodontitis usually involves thorough professional cleaning. In severe cases, surgery may also be necessary.

Trauma to the Face and Jaw

If your dog has been in a fight or been in an accident that has caused trauma to his face or jaw, he may start to open and close his mouth as a way of trying to relieve the pain.

Trauma to the face and jaw can cause bruising, swelling, and even fractures. In some cases, it may also lead to nerve damage, which can cause the dog to drool excessively and experience difficulty swallowing.

Restorative techniques such as crowns or the use of braces may be necessary to correct the alignment of the teeth after an accident.

4. He Is Teething

Teething can be a difficult time for puppies. Not only are their gums swollen and tender, but their new teeth are pushing through the gums. This can cause unbearable pain for the little ones.

To ease their discomfort, many puppies will start to open and close their mouths repeatedly. Once the pain is getting to be too much, they will find relief by chewing on something.

This is when you see your puppy chewing on anything and everything they can get their mouths on. This includes chewing on their paws, blankets, and human fingers and toes.

Teething is typically ended by the time the puppy is six months old. There are a few things you can do to help make teething easier for your puppy.

First, make sure they have plenty of toys to chew on. Frozen fruit or vegetables can also help to soothe their gums.

And, lastly, be patient and understanding – teething is hard for puppies and they need your help to make it through it.

Dogs can experience a great deal of stress and anxiety in certain situations. This may cause them to start opening and closing their mouths as a way of trying to relieve the tension.

Some common sources of stress for dogs include being left alone, loud noises such as fireworks or thunder, changes in routine, trips to the vet or groomer, and meeting new people or animals.

Respiratory Problems

Respiratory problems such as kennel cough, bronchitis, and pneumonia can also cause a dog to start opening and closing his mouth in an attempt to breathe or clear his throat.

Seizure

Seizures can make your dog experience uncontrolled muscle movements. This may cause him to start opening and closing his mouth as well as paddling his legs and drooling.

In the most severe cases, the affected dogs can experience what is called grand mal seizure, which can cause them to lose consciousness and experience muscle contractions that may lead to death.

Hypothermia

As the virus attacks the dog’s nervous system, it can cause them to develop a range of troublesome symptoms, including circling, head tilt, muscle twitches, convulsions with jaw movements which can look like your dog opens and close his mouth repeatedly, excessive drooling, and partial or complete paralysis.

Finally, it could also be a sign of illness or pain. If your dog’s lip quiver is accompanied by other symptoms, it’s best to take them to the vet to get checked out.
