Short answer: Check that a product is made for your pet's species, contains no xylitol (and, for cats, no essential oils or phenols), gives a serving by body weight and lists every ingredient. Then check its honesty: no disease claims, evidence stated, realistic promises. Finally, check who stands behind it: a named company and address, a batch number and best-before date, a safe format for your pet's age and size, and real returns and support. Fail one, put it back.
Why the back of the pack matters
The front of a pack is designed to sell. The back is where a company has to be specific: what is inside, who it is for, how much to give and who is responsible.
Safety checks: 1 to 4
- Made for your pet's species. The label should name the species it is for, with a serving for each. Dogs and cats differ in their mouths, metabolism and evidence base, so "for all pets" with one serving is a warning sign. A cat-and-dog product is fine if it gives a cat serving. A dog-only product never becomes a cat product because you give less.
- No xylitol. Xylitol, sometimes listed as birch sugar, is toxic to dogs and can cause a dangerous fall in blood sugar and liver damage. It turns up in human toothpaste, sugar-free gum and some foods made for people, so keep human products out of your pet's mouth. Check pet products too, from toothpaste to chews. If either name is on the list, put it back.
- For cats: no essential oils or phenols. Cats have very limited ability to process some compounds, because a key liver pathway, glucuronidation, works poorly in cats. Essential oils such as tea tree, peppermint, eucalyptus and clove, and phenols, have no place in a cat product. Check for high-iodine kelp as well, because thyroid conditions are common in older cats. If a cat product smells strongly of mint, read the label twice.
- A serving by body weight. Anything your pet eats or drinks should say how much to give for their weight, with a scoop or measure to match. That is how a 4 kg cat and a 40 kg dog get the right amount. Look for the words serving or feeding amount, and a clear frequency. Weigh your pet rather than guess, and weigh again as they grow or age.
Honesty checks: 5 to 8
- The ingredient list in full. Every ingredient should be listed, including carriers, flavourings and preservatives, and a feed should call itself a complementary feed. A full list lets you and your vet check for anything your pet must avoid, and spot ingredients that do not belong, such as xylitol, onion or garlic. If a company will not say what is in a product, leave it on the shelf.
- No disease claims. In the UK, a non-medicinal pet product may only talk about maintaining health in healthy animals. If a pack names a disease, or promises to deal with one, it is either an authorised veterinary medicine or it is breaking the rules. Implied claims count too: before-and-after photographs, alarming pictures of mouths and published reviews describing a pet getting better all count as advertising.
- Evidence stated, and matched to the product. Good evidence is specific: the exact product or ingredient, the species, the amount, the format and how long the study ran. A study in people, in a laboratory dish or in dogs is not proof that a product works for your cat. Look for companies that name their studies and admit what they do not know. A VOHC seal should match the exact product and species.
- Realistic promises. Soft plaque can begin to harden within about 48 to 72 hours, so honest products talk about helping, supporting and freshening as part of a daily routine. Be wary of instant results, no-brushing promises and tartar that will simply fall away. Hardened tartar, and anything below the gumline, needs your vet. A product that claims to replace the vet belongs back on the shelf.
How we grade evidence
Every scientific statement on this site carries a grade: A product-specific controlled trial · B strain- or species-specific study in dogs or cats · C species mechanistic evidence · D laboratory (in-vitro) evidence · E theoretical rationale. The strength of a claim never exceeds the strength of its evidence. Read our evidence standards.
Trust and fit checks: 9 to 12
- A named company with an address. The pack should name the company responsible for it, with a postal address, not just a website or a social media handle. That company answers for what is inside, for the claims made about it and for putting things right if something goes wrong. If you cannot find out who stands behind a product, you cannot ask them anything, and neither can a regulator.
- A batch number and best-before date. A batch or lot number lets a company trace a product through production, investigate a problem and recall it. A best-before date tells you how long it keeps its quality, which matters for probiotics and anything moist. Check both are printed clearly, and note the batch number if you ever need to report a problem. Store the pack as directed, typically sealed, cool and dry.
- A safe format for your pet's age and size. The right product in the wrong format can still cause harm. Brushes should be soft and sized to the mouth. Chews should be too large to swallow whole and soft enough to dent with your thumbnail, and hard chews are not for cats. Puppies and kittens need gentle tools and products whose label covers their age, and older pets may need a veterinary check before any new routine.
- Returns and real support. Look for a published returns policy and a way to reach a real person who can answer questions about ingredients, servings and suitability. A good company will also tell you plainly when a question is one for your vet rather than for them. If the only contact is a form that never replies, think about what would happen if something went wrong.

When to skip the shop and call your vet
No label check helps a sore mouth. Red or bleeding gums, a loose or broken tooth, swelling or suddenly worse breath need your vet first.
When to see your vet
If you notice loose or wobbly teeth, swelling, discharge, bleeding that does not settle, reluctance to eat, dropping food, drooling, pawing at the mouth or any change in behaviour, please contact your veterinary surgeon promptly. Home care supports professional care — it never replaces it.
