Dog Bleeding From Mouth

Dog Bleeding From Mouth

Anytime we spot our dog bleeding from mouth, most of us go into a panic mood and fail to take the necessary and proper action to deal with the bleeding. It is important to educate ourselves so that should such an occurrence happen, we are in a better situation to handle it.

The best way to go about this is by ensuring that your dog is calm so that it will be less upset and easier to handle. A dog that is hurting may be more agitated and aggressive and may not allow you to examine him closely.


What Causes Dog Bleeding From Mouth?

There are a number of possible causes to this but on this article; we will focus on some of the major and widely known causes:

Inflammation or Gingivitis

In most cases, inflammation is caused by general poor oral health for your dog. A lot of us pet owners tend to take for granted the need for brushing a dog’s teeth or seeking any professional dental cleaning services.

This eventually leads to the buildup of tartar and plaque. With time, this buildup ends up causing conditions such as gingivitis and periodontal disease. Oral unhygienic is something that is easy to avoid!

As a good example, you may notice that, if you haven’t been brushing or flossing regularly, your gum may start bleeding after you brush. This is the exact case with your dog. Ignoring this simple practice may have adverse effects on your dog’s general health.


Although gingivitis is a reversible oral inflammation, periodontitis can cause more harm given the fact that it affects the deeper structures including bones and other ligaments that hold your teeth in place.

Periodontitis is irreversible although it can be slowed and even stopped.

Teeth Discoloration and Dog Bleeding Gum

Although we tend to downplay the discoloring of our dog’s teeth, this should be a cause for concern. You should look out for symptoms like a black tongue which could be an indication that, veterinary care is necessary because of a possible lack of niacin, ulcerations or an underlying dental problem.

Foreign Objects and Mouth Bleeding

This is a very common occurrence. Your dog’s bleeding from the mouth could have been occasioned by an injury from chewing objects like toys and other plastics. Such injuries can cause bleeding to the dog gums or dental injuries.

To the surprise of many, ingestion of something toxic like chocolate or antifreeze has the potential to cause bleeding to a dog gums. The best bet is to always be watchful of what your dog plays with and if you notice something strange to their behavior, you should always consult a vet.

Stomatitis in Dogs and It’s Major Causes

In simple terms, stomatitis refers to a condition that is occasioned by irritation or inflammation to the soft tissues (gum and tongue) in an animal's mouth. This condition can bring about major problems like when bacteria or an infection enters the dog's blood stream.

Symptoms and Types of Stomatitis

Common symptoms or signs of Stomatitis include but are not limited to:

  • Ulcerated tissues
  • Fluid buildup in the gums
  • ​Excessive Pain
  • ​Extensive teeth plaque
  • ​Bad breath
  • Excessive drooling or saliva

Major Types of Inflammation

  • Ulcerative Stomatitis:

This condition comes about when a significant portion of gum tissue is lost in a dog's mouth; it is usually accompanied by inflammation of the oral tissues.

  • Oral Eosinophilic Granuloma:

A dog with this condition suffers from a mass selling or growth in its mouth.

  • Gingival Hyperplasia:

Though often times confused with Oral Granuloma, hyperplasia occurs when there is a significant increase in the gum tissue.

  • Lymphocytic Plasmacytic:

This condition occurs when there is the presence of white blood cells -plasma cells and lymphocytes in the mouth.

Causes of Stomatitis

Stomatitis can affect dogs within any age group. For example, in puppies, inflammation is commonly caused by overcrowding of teeth in the mouth.

A number of metabolic disorders are known to be the cause of this type of inflammation. Some of them include lymphoma, an excessive amount of waste products found in the blood stream, an inflamed blood vessel in the mouth (as is common with diabetes) and low levels of the hormone (commonly known as parathyroid).

Others are Infectious diseases and injuries to the mouth.

How the Diagnosis is Done

A vet will start by examining the dog's mouth for teeth decay, unusual lesions or even plaque and any other signs that may be the cause of the inflammation.

Depending on the severity of the condition, a laboratory blood work is necessary so as to rule out any other underlying medical condition occasioned by the inflammation.


Since most of the gum bleeding is as a result of poor oral hygiene, this can be prevented by maintaining a hygienic dental formula. Ensure you give your dog a regular brushing of the teeth and regular professional animal dental cleanings.

You may ask how but the simple answer is: by regularly brushing, you are stimulating healthy gums and removing plaque which in return ward off tartar – all these have the potential of causing gum disease.

In addition to regular brushing, give your dog some veterinarian approved dental chews and bones. These are very good in keeping the teeth and gums healthy. Remember to keep your eye on them as they are chewing to avoid incidents like choking. You can check out some of the best dental chews here.
