Why Does My Dog Have Bad Breath?

Bad breath usually comes from plaque, tartar and gum disease — not something your dog ate. Regular dental care (brushing, dental chews, checkups) fixes most cases.

Common causes

• Dental disease: plaque and tartar buildup.
• Diet: certain foods and treats.
• Other issues: stomach, kidney or mouth problems (less common).

What to do

• Brush teeth 2–3 times a week with dog toothpaste.
• Offer a daily dental chew or toothbrush toy.
• See a vet if breath is suddenly severe or sweet-smelling.
