Gingivitis in Dogs

Gingivitis is a reversible inflammation of the gums and is considered the earliest stage of periodontal disease. In the early phases of gingivitis, some plaque is present and there is mild redness of the gums, but the gingival surfaces are smooth.

The gingival sulcus (gum pocket) is the narrow space between the inner wall of the gum and the tooth. As gingivitis develops, the bacteria present in these pockets changes for the worse, and the accumulation of more bacteria, which release toxins, destroy gums.

In advanced gingivitis, there is plaque and calculus under the gums, moderate-to-severe redness of the gums, and the gum surfaces are irregular. Dental calculus is calcium phosphate and carbonate mixed with organic matter, while plaque is a collection of food, debris, bacteria, dead skin cells, and mucous that forms within 24 hours on clean tooth surfaces. The gum responds to plaque with an inflammation of blood vessels, swelling, and collagen loss.

More than 80 percent of pets aged three years or more have gingivitis. It develops earlier in life in toy breeds, and in general, affects dogs earlier in life than it does cats.

Symptoms and Types

  • Red or swollen gums, especially on the side of the gum facing the inner cheeks

  • Bad breath (halitosis)

  • Variable amounts of plaque and calculus

Causes

Plaque accumulation is one of the main causes leading to gingivitis in dogs. Predisposing factors include:

  • Old age

  • Crowded teeth

  • Soft food

  • Open-mouth breathing

  • Bad chewing habits

  • Lack of oral health care

  • Uremia and diabetes mellitus

  • Autoimmune diseases

Diagnosis

Your veterinarian will perform a thorough physical exam on your dog, taking into account the background history of symptoms and possible conditions that might have led to this condition. You will need to give a thorough history of your dog's health and the onset of symptoms, such as when the bad breath began, what your dog typically eats, whether your dog has had trouble eating/chewing, and whether your dog has had any previous health conditions. The routine you have been using to keep your dog's teeth clean, if you have been using one, should be shared with your veterinarian as well, including the products you use.

Part of the physical exam involves closely examining your dog's mouth to identify the condition. Your veterinarian will then make an appointment with you to bring your dog in for a dental exam. During the dental exam, your dog will be anesthetized. Your veterinarian will check the depth of the gum pockets, the amount of plaque and bacteria on the surface of the teeth, and will pull any teeth that are rotten or that are too crowded. All of the plaque and calculus will be removed using a scaling process that is done with special dental equipment, and if necessary, root planning. The tooth surfaces will be polished and the teeth will be reexamined after cleaning.

Treatment

If teeth are overcrowded or baby teeth are present in an adult dog, your veterinarian may remove some teeth. Special dental tools will be used to remove all plaque and calculus, to polish the teeth, and rinse them. Your vet will then teach you how to clean your pet’s teeth, and appointments for follow-up examinations should be scheduled.

Living and Management

You can help maintain your dog’s oral health care by brushing or rubbing (with a special finger pad) its teeth once a day or at least twice a week with veterinary toothpaste. Your veterinarian may also give you a veterinary antibacterial solution to squirt on your pet’s teeth to decrease plaque build-up. Rawhide chew strips and specialized food recommended to you by your veterinarian can reduce tartar and improve the dog's oral health as well.

What does it mean when your pet has an autoimmune disease like immune-mediated thrombocytopenia?

blog_ autoimmune-disease _banner.png

Immune-mediated thrombocytopenia (IMT) is a condition in which the animal’s immune system attacks and destroys blood platelets. Without platelets, blood cannot clot effectively, leading to internal or external bleeding. This can cause anemia, and is dangerous in times of injury or surgery. IMT can be a primary condition or it can be caused by another illness (including cancer, certain tick-transmitted diseases as well as some viral and bacterial infections). IMT generally responds to treatment, but it can be fatal. Relapses are common.

About Immune-mediated thrombocytopenia (IMT)

IMT is an autoimmune disease. Autoimmune diseases result when the body’s immune system has become unrecognizable/does not recognize itself. In these cases, cells that normally attack invading viruses and bacteria begin attacking the body’s own cells, resulting in damage.


In dogs and cats with IMT, the body’s platelets are attacked and destroyed, resulting in reduced numbers of platelets in the blood vessels. Platelets (also called thrombocytes) are cells that are needed to form blood clots and repair damaged blood vessels. Thrombocytopenia occurs when there are too few platelets in the blood.

Adequate numbers of platelets are essential for survival. Platelets help repair obvious injuries, such as open wounds, as well as microscopic injuries that occur in day-to-day life. If platelet numbers are too low, uncontrolled bleeding can occur. If treatment is unsuccessful, the patient can bleed to death.

IMT can be a primary condition or it can be caused by another illness or event. The underlying cause of primary IMT is rarely determined. Female dogs are more likely to be diagnosed with IMT, but there is no corresponding gender predisposition in cats. Secondary IMT can be associated with certain cancers (including lymphoma); exposure to certain drugs (including some antibiotics); tick-transmitted diseases (such as ehrlichiosis, babesiosis, and anaplasmosis); and some viral and bacterial infections, including canine distemper virus in dogs and feline leukemia (FeLV) and feline immunodeficiency virus (FIV, or feline AIDS) in cats.

Symptoms and Identifying IMT

Platelets are responsible for helping form blood clots and repair damaged blood vessels, which is why the most common sign of IMT is spontaneous bleeding or the inability to stop bleeding. If IMT is caused by another illness, additional clinical signs can result from the underlying condition. Clinical signs of IMT can vary in severity and include:

  • Weakness

  • Lethargy (tiredness)

  • Appetite loss

  • Vomiting blood

  • Bloody diarrhea or melena (digested blood that appears in feces)

  • Bruising on the skin

  • Bleeding from the nose

  • Bleeding from the gums

  • Bloody urine or bleeding from the penis or vulva

  • Coughing blood or difficulty breathing

Bleeding can also occur within the brain, causing seizures; within the eyes, causing blindness; or within the abdomen or chest cavity. Severe bleeding can be fatal, especially if it occurs rapidly. If significant blood loss occurs, additional clinical signs (such as pale gums, weakness and even collapse) may be associated with anemia (inadequate numbers of red blood cells).

Owners may also notice other evidence of bleeding, such as minor cuts and scratches that continue to bleed, a heat cycle that seems prolonged or excessive, or skin bruising after playing or grooming.

There is no specific test to diagnose IMT. Your veterinarian will likely recommend blood testing to help confirm a suspected diagnosis of IMT and rule out other conditions that can cause low platelet numbers.

Some veterinarians can perform initial testing at their offices. In other cases, tests are sent to a diagnostic laboratory and results are available in a few days. If your veterinarian suspects an underlying illness (such as FeLV or ehrlichiosis), he or she may recommend more testing.

Who is predisposed for IMT?

Certain dog breeds, such as German Shepherds and Old English Sheepdogs, may be genetically prone to developing primary IMT.

Treatment for IMT

Because IMT is caused by an overactive immune system, initial treatment is aimed at suppressing the immune system and stabilizing the patient. Steroids (given at high doses) are the most common medication prescribed. Additional therapy may include intravenous fluids and supportive care. If the underlying cause of IMT can be treated, such therapy is also generally initiated.

Some pets don’t respond adequately to steroids. In these cases, additional medications can be given to manage the condition.

During treatment, frequent blood testing is required to ensure an adequate response to therapy. Once a pet responds to treatment, medication dosages are gradually adjusted and blood tests are repeated periodically to monitor for relapses.


IMT generally responds to treatment, but it can be fatal. For pets who survive, relapses commonly occur. Your veterinarian may recommend periodic recheck examinations and frequent repeat bloodwork for the life of your pet to help identify and treat relapses early.
