My dog has bad breath — what now?

Bad breath usually comes from periodontal disease, but it can also signal a mouth tumour, kidney disease or diabetes. Check the teeth and gums before buying dental chews.

First, how urgent is this?

Go now

  • Bleeding from the mouth, constant drooling, or swelling of the face.
  • Refusing food completely, with very low energy.
  • Obvious effort to breathe.
  • Sudden collapse, or unable to stand.

Contact your vet today

  • By age 2, eight in ten dogs already have some periodontal disease.
  • Visible tartar, red or receding gums.
  • Bad breath with drinking clearly up for several days.
  • Chewing on one side, dropping food, or drooling.
  • Weight down 5% or more within two weeks at the same time.

Record and observe

  • The odd bout of bad breath with clean teeth, improving after brushing.
  • A dental scale booked in and brushing at home, with the breath improving.
  • Already under vet care: record how often you brush and how the breath changes, and bring it to the next visit.

Before you set off

  • Photos of the mouth and teeth.
  • When the bad breath started, and whether sudden or gradual.
  • Any tartar, bleeding gums, loose or broken teeth.
  • Chewing habits, drooling and appetite.
  • Water intake and weight records.
  • Do not use human toothpaste or mouthwash, and do not pull teeth or give human antibiotics.

What your vet may ask and do

  • Ask: when the breath changed, and whether there is drooling or difficulty chewing.
  • Ask: any change in drinking, appetite or weight.
  • Do: a mouth exam, including probing the gums.
  • Do: a dental scale, usually under general anaesthetic with dental X-rays.
  • Do: extractions where needed, or referral to a dental specialist.
  • Do: blood tests (kidney values, glucose) to rule out a metabolic cause.
  • Do: a home brushing plan and regular checks.
