Your dog yawns and you get a whiff you can't unsmell.

Bad breath often starts in the mouth.

Daily brushing, regular dental checks, suitable chews, and a close eye on the gums are the core of oral care.

Gut support is an additional part of a routine, and it does not replace dental care.

Why bad breath deserves attention

AAHA lists dental warning signs, including bad breath, red gums, drooling, and difficulty eating.

Plaque bacteria can contribute to mouth odor.

Our guide to dog bad breath causes and symptoms explains what else to watch for.

How the gut and mouth may be linked

Five daily dental habits that work

1. Daily brushing

Brush gently with dog-safe toothpaste.

Never use human toothpaste, which may contain ingredients unsuitable for dogs.

Lift the lip and brush gently along the outer tooth surfaces and gumline.

Build up gradually if your dog is new to brushing, and reward cooperation.

2. VOHC-approved dental chews

Look for products accepted by the Veterinary Oral Health Council.

The seal applies to specified plaque or tartar claims.

Check the current accepted list at vohc.org.

Size the chew to your dog.

3. Professional cleanings

Professional dental care may include cleaning under anesthesia and dental X-rays.

Cleaning only the visible crowns cannot assess or address problems below the gumline.

4. Water additives

Choose a water additive with evidence for its intended use.

Follow its directions, and make sure your dog continues to drink normally.

5. Dental diet options

Some dental diets are designed to reduce plaque or tartar.

Use a product with evidence for that purpose and follow its feeding directions.

Daily care and professional care

These approaches have different roles in an oral-care routine.

Oral-care options
Approach Role
Brushing Daily plaque control
VOHC-accepted product Additional plaque or tartar support
Professional examination Assessment of teeth, gums, and hidden disease

Signs it's time to call your vet

Book a visit if you notice any of these.

Don't wait for the next annual checkup.

  • Persistent bad breath that doesn't improve with brushing
  • Red, swollen, or bleeding gums
  • Brown or yellow tartar along the gumline
  • Pawing at the mouth, dropping food, or chewing on one side
  • Loose, broken, or missing teeth
  • Visible pus, facial swelling, or a draining tract below the eye
  • Sudden reluctance to eat hard kibble or chew toys
  • Excessive drooling, especially with a blood tinge
  • Sudden weight loss, a poor appetite, or any change in breathing

Your daily dental routine

Keep the routine manageable: brush daily and follow the dental-care plan recommended for your dog.

See our guides to wellness habits and behavior for the wider routine.

Where supplements fit

A supplement can sit alongside brushing and dental care.

If you choose Advanced K9 Microbiome Care, follow the product directions.

Does oral health support replace brushing?

No, it doesn't.

Chews, water additives, and dental diets are additions to brushing.

Professional care is still needed when a dental examination identifies a problem.

What is the gut-mouth axis?

It's the idea that bacteria in the mouth and gut can influence each other.

Research on this link in dogs is still early.

Are dental chews enough without brushing?

Chews are an addition to the routine.

They do not replace brushing or a dental examination.

Does kibble clean teeth better than wet food?

Ordinary kibble is not a substitute for brushing.

A dental diet needs evidence for its plaque or tartar claims.
