They yawn in your face. You recoil. You laugh it off as “dog breath”. But here’s the thing: a dog’s mouth shouldn’t smell bad, and the type of smell can tell you a surprising amount.
Did you know?
No. 1
Dental disease is the most common health problem in UK dogs, affecting 12.5% of dogs seen by vets in a year, more than ear infections (7.3%) or obesity (7.1%).

The breath decoder 👃
Have a (brave) sniff, then find your smell:
🐟 Fishy or just “bad”
Usually plaque and tartar: bacteria building up at the gumline. Very common and very fixable. (Fun fact: if it’s properly fishy, some dogs have simply been licking their bottom. Anal glands smell exactly like that.)
🍬 Sweet or fruity
See your vet. A sweet smell can be a sign of diabetes, especially if your dog is also drinking and weeing more.
🚽 Like wee
See your vet. Breath that smells of urine can point to a kidney problem.
🤢 Rotten, with drooling or not eating
See your vet soon. This can mean a broken tooth, an abscess or something stuck in the mouth.
💨 Changed suddenly
Any sudden new smell is worth a check, even if your dog seems happy.
The 30-second weekly mouth check
⚡ Do this every Sunday
- Lift the lip in good light. Look at the front and the back teeth.
- Yellow-brown build-up at the gumline = plaque and tartar.
- Healthy gums are pink. Red, swollen or bleeding? Book the vet.
- Have a sniff. Note anything new.
Moments every owner will recognise
Scene 1: The morning yawn
Your dog yawns 10cm from your face at 6am. If you’re thinking “that’s worse than last month”, trust that instinct.
Scene 2: The chew that disappears in 4 seconds
Dental chews only work if they get chewed. If yours vanish in one gulp, they’re a treat, not dental care.
Scene 3: The toothbrush standoff
Day one: enthusiasm. Day four: the toothbrush is in a drawer and the dog hides when he sees it. Very normal.
What actually helps
- Brushing is the gold standard. Use a dog toothpaste, never human toothpaste (it can contain xylitol, which is toxic to dogs).
- Chews and toys designed for teeth, chosen for your dog’s size.
- A daily food add-on for the days brushing doesn’t happen (which, let’s be honest, is most of them).
- A yearly dental check with your vet. Tartar that’s already hard needs a professional clean.

Questions owners ask us
Is “dog breath” just normal?
A faint doggy smell, yes. Breath that makes you turn your head away usually isn’t; it’s most often plaque.
My puppy’s breath smells sweet. Should I worry?
Puppy breath is famously sweet-ish while adult teeth come in. In an adult dog, a sweet smell is worth mentioning to your vet.
Do cats get bad breath too?
Yes, and dental disease is very common in cats. The same rules apply: a sudden or strong smell means a vet check.
Can I use my toothpaste?
No. Human toothpaste can contain xylitol and isn’t meant to be swallowed. Use a pet toothpaste.

VET: Bad breath is a symptom, not a condition. The PDSA notes that many dogs show no symptoms of dental disease at all, and that most dogs who have it "require a dental procedure", which can only be done safely under general anaesthetic. Brushing is the measure with the strongest evidence behind it: "brushing away plaque before it turns into solid tartar is the best way to prevent dental disease". Never use human mouthwash or antibacterial gels on a dog.
