Causes

Let’s take a look at some of the most common reasons why your dog may be bleeding from its mouth.

Poor Oral Hygiene

One of the main reasons for a dog’s bleeding mouth is poor oral health. Often, pet owners fail to recognize the importance of brushing and cleaning their dog’s teeth.

As a result, their dog’s mouth becomes a breeding ground for bacteria, plaque, and other problems.

Gingivitis

Gingivitis is among the most common problems that result from poor dental hygiene. It causes the gums to become inflamed due to bacteria that grow inside the mouth. It can lead to a dog bleeding from its mouth if not treated on time. Thankfully, gingivitis is reversible and can be cured.

Periodontitis

Periodontitis is a serious disease that can affect the ligaments and bones that hold the teeth in place. While this problem cannot be cured, its effects can be slowed down.

Chewing Hard Objects

Sometimes, dogs may chew on hard objects that hurt their gums and cause dental injuries. If you see your dog’s gums bleeding heavily or notice cuts on them, it is most likely from chewing on a hard or sharp object rather than dental disease.

Be careful and don’t let your dog chew on splintering sticks, broken glass, rocks, pebbles, plastic wrappers, cans, and other hard objects.

Ingesting Foreign Substances

From time to time, dogs can unknowingly ingest harmful substances. Chocolate, anti-freeze, rat poison, and other poisonous substances can result in bleeding from the mouth.

In such situations, contact a vet at once.

Ulcers

An ulcer can cause your pet to bleed from the mouth. Stomach ulcers can result in dark excrement due to the presence of digested blood.

Tumors

If your dog has a tumor in the mouth, it can cause bleeding until it has been removed. Tumors can be indicative of cancer.

This condition is more common among old dogs bleeding from their mouths.  This is of course serious and requires urgent medical intervention.

What To Do

A dog bleeding from its mouth is not an unusual occurrence. Nevertheless, there are a few things we can do to find and rule out possible causes. 

Check the Mouth

Inspect your dog’s mouth. Take a look at its tongue, gums, jaw, and top of the mouth. This will help you rule out possible causes behind your dog’s bleeding.

Here are a few things to take note of.

Did your dog bite its tongue?

Your dog might have accidentally bitten its tongue or chewed on something that resulted in a puncture wound. 

Are your dog’s gums swollen?

Check for swelling. If your dog’s gums are bright red, the bleeding may be due to inflammation or infection. 

Do your dog’s teeth look healthy?

Teeth-related problems will affect your dog’s oral health. Loose or broken teeth will cause bleeding.

However, if you observe bleeding from the deeper and less visible corners of your dog’s mouth, then you should see a vet.

If you’re unable to determine the cause, it is best to visit the vet to rule out any serious health issues.

Check the Belly, Ears, and Areas Around the Mouth

Besides the mouth, you should also check for bruises on your canine’s belly and small red dots on its ears and around the mouth.

These are signs of internal bleeding which require immediate medical intervention.

Treatment

There are a variety of treatments available depending on the cause of bleeding.  

Severe Blood Loss

If your dog is bleeding profusely, he or she may require a blood transfusion.

In such cases, the vet will administer an IV drip and/or arrange for blood transfusion.

An X-ray and a complete blood count (CBC) test may also be performed.

Dental Problems

For serious dental problems that involve deep lacerations, sutures may be necessary to keep your dog’s mouth from bleeding.

The vet may also prescribe antibiotics and require that your dog’s mouth be cleaned and disinfected several times a day. 

Foreign Objects

Lastly, if your canine has a foreign object stuck in its mouth, surgery may be necessary to remove it. The surgeon will sedate your dog and perform the operation.

Can a dog bleeding from its mouth die? Unfortunately, yes. Traumatic injuries, accidents, and the ingestion of harmful substances like rat poison can cause internal bleeding and eventually death.

How To Prevent It?

While it’s difficult to control everything that our dogs come in contact with, there are certain things we can do to nurture them and ensure that our dogs have access to good oral health.

Here are some easy ways to keep your dog’s teeth clean.

1. Schedule Regular Teeth Cleaning

Dogs need to get their teeth cleaned too. Adult dogs should see a veterinary dentist at least once a year.

Smaller dogs should see one every six months since the roots of their teeth are more shallow.

2. Brush Your Dog’s Teeth

Use a pet toothbrush with soft bristles. You can also use a finger brush with toothpaste that’s made for dogs.

Regular toothpaste for people can be toxic to dogs.

3. Feed Your Dog Crunchy Kibble

Dry crunchy food is better for your dog’s oral health than soft wet food. The friction of dry kibble against your dog’s teeth helps scrape away any tartar.

Soft food has a greater tendency to stick to their teeth encouraging plaque build-up.

4. Chew Toys for Oral Health

Did you know that some dog treats can harm your dog’s teeth? When selecting chew toys, opt for non-abrasive ones.

If you can find toys with a seal from the Veterinary Oral Health Council, even better.

Ensure Proper Oral Hygiene

Whoever said that prevention is better than cure is absolutely right. Since most cases of dogs bleeding from their mouth are attributed to poor oral hygiene, you need to ensure that you brush and clean your pet’s mouth regularly.

Keep your pet away from hard or sharp objects and toxic substances. However, if bleeding from the mouth happens due to an underlying health condition, consult a vet immediately.
