Can Dogs Get Stomatitis? Is Excessive Drooling a Warning Sign?

Dogs can get stomatitis, and excessive drooling may be one of the signs pet parents should not ignore. While many people have heard of feline stomatitis, dogs can also suffer from painful inflammation and ulcers inside the mouth.

Canine stomatitis, often referred to as Canine Chronic Ulcerative Stomatitis (CCUS), is a painful oral condition that causes inflammation and ulcers on the gums, inner cheeks, lips, tongue, and other soft tissues in the mouth. These ulcers can make eating, drinking, chewing, and even opening the mouth uncomfortable for your dog.

Because mouth pain can seriously affect a dog’s appetite, mood, and overall health, early observation and proper veterinary care are very important.

What Is Canine Stomatitis?

Canine stomatitis is a chronic inflammatory condition of the mouth. In many cases, ulcers appear where the teeth come into contact with the oral mucosa, especially along the gums, cheeks, and lips.

These ulcers may look red, swollen, raw, or even bloody. Some dogs may also develop sores on the tongue. In more severe cases, the mouth may produce pus, and the skin around the lips may become irritated due to constant drooling.

Unlike simple bad breath or mild tartar buildup, stomatitis is usually painful and should be evaluated by a veterinarian.

Common Symptoms of Stomatitis in Dogs

The most obvious sign of canine stomatitis is inflammation or ulceration inside the mouth. However, many dogs do not allow owners to check their mouths easily, so behavioral changes can be just as important.

Watch for these signs:

• Bad breath
• Excessive drooling
• Loss of appetite
• Weight loss
• Reluctance to chew hard food or treats
• Pawing at the mouth
• Bleeding gums
• Red, swollen, or ulcerated areas inside the mouth
• Reluctance to open the mouth
• Irritation or dermatitis around the lips

Excessive drooling can happen because oral ulcers are painful. When a dog avoids chewing or keeps the mouth partially open, plaque and bacteria may build up more easily, which can worsen oral irritation over time.

Can Stomatitis Cause Sores on a Dog’s Tongue?

Yes. Canine stomatitis can cause sores or ulcers on the tongue, gums, cheeks, lips, and other areas inside the mouth. Tongue ulcers may make eating especially difficult because the tongue moves constantly during chewing, drinking, and licking.

If your dog suddenly refuses food, drops kibble from the mouth, drools more than usual, or reacts painfully when you touch the face or mouth area, it is best to schedule a veterinary dental exam.

Will Canine Stomatitis Go Away on Its Own?

Canine stomatitis usually does not resolve properly without treatment. Because it is often linked to chronic inflammation, plaque, bacteria, immune response, or dental disease, professional care is usually needed.

Treatment may include:

• Veterinary oral examination
• Professional dental cleaning
• Medication to control pain or inflammation
• Treatment of infection if present
• Tooth extraction in severe or chronic cases
• Long-term home dental care

In some dogs, extracting teeth that come into contact with ulcerated tissue may help reduce irritation and allow the mouth to heal. Your veterinarian will recommend the best treatment plan based on your dog’s condition.

Can I Use Human Oral Ointment on My Dog’s Mouth Ulcers?

No, it is not recommended to use human oral ointment on dogs unless your veterinarian specifically instructs you to do so.

Human medications may contain ingredients that are unsafe or toxic to dogs. Dosage is also very different between humans and pets. Applying the wrong product can irritate the mouth further or cause poisoning if swallowed.

If your dog has mouth ulcers, bleeding gums, severe bad breath, or pain while eating, contact your veterinarian instead of using human oral products.

How to Help Prevent Oral Problems in Dogs

While not every case of stomatitis can be fully prevented, daily oral care can help reduce plaque buildup, support cleaner teeth, and make it easier to notice early changes in your dog’s mouth.

Here are two key habits that can support your dog’s oral health.

1. Build a Daily Oral Care Routine

Brushing your dog’s teeth is one of the most effective ways to reduce plaque and maintain oral hygiene. However, many dogs dislike toothbrushes, and some pet parents find brushing difficult to do consistently.

For an easier daily option, you can use Petsgofun Oral Care Dental Foam for Dogs & Cats as part of your pet’s oral care routine.

This dental foam is designed for simple everyday use:

• No toothbrush needed
• No rinsing required
• Gentle foam texture spreads around teeth and gums
• Helps freshen bad breath
• Suitable for both dogs and cats
• Easy to use in multi-pet households

To use it, simply lift your pet’s lips, pump the foam onto the teeth and gum line, and let your pet lick naturally. It is a quick way to support daily oral hygiene, especially for pets who resist traditional brushing.

2. Schedule Regular Veterinary Dental Checkups

Daily care at home is important, but it cannot replace professional veterinary dental care. Plaque and tartar can build up under the gumline, where home products may not reach effectively.

Over time, tartar can contribute to gum inflammation, gum recession, tooth loss, and chronic oral discomfort. That is why regular dental checkups are essential.

For most dogs, an annual dental exam is a good starting point. Your veterinarian can assess whether your dog needs professional dental cleaning or further treatment.

When Should You See a Vet?

You should contact a veterinarian if your dog has:

• Mouth ulcers
• Bleeding gums
• Loose teeth
• Sudden loss of appetite
• Severe bad breath
• Excessive drooling
• Visible mouth pain
• Swelling around the mouth
• Pus or discharge
• Weight loss

Dental foam and home oral care products can help support everyday hygiene, but they are not a treatment for serious oral disease. If your dog is already showing signs of pain, bleeding, or infection, professional care is necessary.

Final Thoughts

Yes, dogs can get stomatitis, and excessive drooling can be a warning sign. Canine stomatitis can cause painful mouth ulcers, bad breath, loss of appetite, and major discomfort in daily life.

The best approach is to combine early observation, regular veterinary dental exams, and consistent home oral care. For daily maintenance, Petsgofun Oral Care Dental Foam for Dogs & Cats offers a simple, no-rinse, no-toothbrush option to help freshen breath and support cleaner teeth.

A healthy mouth helps your dog eat comfortably, play happily, and enjoy a better quality of life.
