Chews and dental products: start with the VOHC seal
What the seal does and does not say
The VOHC does not test products itself; it reviews the manufacturer's submitted studies against its standards for plaque and tartar control, and the seal can be awarded for plaque, calculus (tartar), or both, per vohc.org. That makes the seal a filter for the dental aisle: a product with it has shown its effect in trials that met a veterinary-dental bar. The seal says nothing about calories, ingredients, or how safe a chew is for aggressive chewers - those are separate decisions.
The product types, ranked by evidence
| Type | How it helps | Notes |
|---|---|---|
| Tooth brushing (dog toothpaste) | Mechanically removes plaque daily | The gold standard per the WSAVA guidelines; seal-accepted pastes exist |
| VOHC-sealed dental chews | Chewing action scrapes plaque; some add chemical action | Check the seal; size the chew to the dog; supervise |
| Dental diets | Kibble engineered to scrub or chemically slow plaque | Some carry the seal; ask your vet whether one fits your dog |
| Water additives | Reduce bacteria in the mouth | Some accepted; a helper, not a substitute |
Chew safety, briefly
Two rules come straight from VOHC's own safety guidance: give the right-sized product for your dog's body weight, and supervise while they chew - obstructions happen when pieces are gulped. And hardness matters as much as hygiene: chews that do not bend and give under pressure (antlers, hooves, hard nylon, bones, ice) can crack teeth - the WSAVA guidelines note that even VOHC-accepted products must have a consistency that does not damage teeth. Our chew safety guide has the bend test.
Building a sensible routine
One plan to discuss with your vet: brush daily or near-daily, add one VOHC-sealed chew on the days you do not brush, keep up the oral exams your vet recommends, and expect professional cleaning when tartar wins anyway. That combination covers plaque control at home and tartar removal at the clinic - see what a cleaning involves so the recommendation makes sense when it comes.
