How We Ranked These
Every product on this list was scored using KibbleIQ’s Treats Rubric v1.0, which evaluates protein quality, filler content, preservative safety, calorie density, size-tier appropriateness, and functional-claim verification on a 0–100 scale. For dental chews specifically, the rubric awards a stacked +6 bonus (function-class +3 for dental-chew + functional-claim +3 for verified VOHC seal) to products with Veterinary Oral Health Council acceptance.
The VOHC Seal of Acceptance is the gold standard for dental-claim evidence in pet products. VOHC reviews manufacturer-submitted clinical trial data demonstrating measurable plaque or tartar reduction versus a control group, and awards the Seal only to products that meet specified efficacy thresholds. Very few dental chews carry it — most dental claims on pet treats are marketing language without the trial data to back them.
We also weighted ingredient-panel cleanliness (no BHA, BHT, ethoxyquin, artificial colors, or by-product meals), size-tier appropriateness to pet weight, and calorie density relative to the 10%-of-daily-calories feeding ceiling. The top picks below balance VOHC-verification, ingredient quality, and correct sizing for the intended pet.
Our Top Picks
1. Greenies Original Regular Dental Dog Treats — C (58/100)
The default VOHC-accepted dental chew for dogs. Greenies has been VOHC-verified for plaque and tartar control since 2005 and is the single most-studied dental chew in the dog category. The ingredient panel is grain-heavy (wheat flour, glycerin, wheat gluten) and the calorie density is high (91 kcal per Regular-size chew), which keeps the rubric score at C/58 despite the VOHC advantage. The functional tradeoff: you’re accepting a mid-tier panel in exchange for documented plaque-and-tartar reduction.
Greenies sells six size tiers (Teenie, Petite, Regular, Large, Jumbo) matched to dog weight. Size correctly to the dog — Regular is for 25–50 lb dogs; undersizing reduces chewing time and dental efficacy, oversizing poses GI risk. Read our full Greenies review → · Shop on Amazon →
2. Whimzees Stix Medium Dental Dog Chews — B (76/100)
The cleanest plant-based dental chew on the mainstream shelf and our highest-scoring dog dental chew. Whimzees uses a simple nine-ingredient potato-starch-based formula with no grain, no BHA, no artificial colors, and no animal protein — which means the ingredient-panel rubric score is substantially higher than Greenies. The important caveat: the Stix shape specifically is not VOHC-accepted, even though other Whimzees shapes (Toothbrush, Alligator) carry the seal. If VOHC-verified efficacy is your primary decision factor, use a Greenies shape or a Whimzees Toothbrush. If ingredient-panel transparency matters more, Whimzees Stix is the stronger pick.
Four sizes matched to dog weight (XS 5–15 lb, S 15–25 lb, M 25–40 lb, L 40–60 lb). Medium (87 kcal) is the most commonly sold size. Read our full Whimzees Stix review → · Shop on Amazon →
3. Greenies Feline Original Tuna Flavor Dental Cat Treats — C (61/100)
Essentially the only mainstream VOHC-accepted dental treat for cats. Greenies Feline leads with chicken meal (the best possible first ingredient for a grain-based feline dental crunch) and adds taurine and natural preservation. The VOHC seal is the defining feature — very few cat dental treats carry it, and none of the better-scoring cat treats (PureBites, Inaba Churu, Tiki Cat Stix) make dental claims. The grain-heavy panel (corn gluten meal, wheat, rice flour) is the rubric cost.
Feed the package-recommended daily serving (typically 15–25 treats per day for an adult cat) for VOHC-verified dental efficacy; at 1.4 kcal per treat, this fits comfortably inside a 10-lb cat’s 25-kcal daily treat budget. Cats that gulp rather than chew won’t get the dental benefit — for gulpers, a non-dental A-tier treat is a better use of the budget. Read our full Greenies Feline review → · Shop on Amazon →
Honorable Mentions
Virbac C.E.T. VeggieDent FR3SH Dog Chews. VOHC-accepted plant-based dental chew with chlorophyll and plant enzymes. Not currently in our scored database, but VeggieDent is a legitimate alternative for dog-parents who want a VOHC-accepted vegetarian option. Vets often stock these as an alternative to Greenies for dogs with wheat sensitivities. Shop on Amazon →
OraVet Dental Hygiene Chews. VOHC-accepted with delmopinol, a chemical plaque-prevention agent that coats the tooth surface. Only veterinarian-distributed or online-specialty. Better science than Greenies for the specific claim of plaque-prevention (not just reduction), but availability is a constraint and we haven’t scored it in our database.
Purina Dentalife. VOHC-accepted mass-market alternative to Greenies at a lower price point. Ingredient panel is lower quality than Greenies (we haven’t formally scored it but expect D-tier based on similar formulations), but the VOHC seal is genuine. Reasonable budget choice if Greenies is unaffordable.
What to Look for in a Dental Chew
VOHC Seal of Acceptance is the only reliable dental-claim evidence. The VOHC reviews manufacturer-submitted plaque and calculus reduction trial data and publishes a complete list of accepted products on vohc.org. Any dental-chew marketing claim without the VOHC seal is language not backed by a specific clinical trial. Start from the VOHC list, not from the pet-store shelf.
Chewing duration matters more than ingredient formulation for dental function. Dental chews work through mechanical abrasion as the pet chews the treat — the tooth penetrates into the chew and the chew surface abrades plaque off the tooth in the process. A chew that’s the wrong size for the pet (too small, swallowed whole; too large, not completed) produces no dental benefit. Dogs that gulp instead of chewing get essentially zero benefit from dental chews; for those dogs, focus on daily brushing and professional cleanings.
Size to the pet, not to the price. Greenies offers six sizes; Whimzees offers four; both are sized for specific dog-weight ranges. Feeding an oversized dental chew creates choking risk and reduces efficacy; an undersized chew is swallowed too fast for mechanical benefit. Check your pet’s weight against the package chart every time you switch brands.
Calorie budget awareness. A Greenies Regular is 91 kcal; a Whimzees Medium is 87 kcal; a Greenies Feline is 1.4 kcal. Cat dental treats are designed for high-count daily feeding; dog dental chews are designed for once-daily feeding. Always keep treats at or under 10% of daily calorie intake — a 50-lb dog’s ~110-kcal treat budget means one Greenies Regular is essentially the entire day’s treat allowance.
Dental chews are a brushing supplement, not a replacement. The American Veterinary Dental College and AVMA both emphasize that daily tooth brushing remains the highest-impact dental intervention for dogs and cats. A VOHC dental chew is the next-best option when brushing isn’t feasible or as an additional dental intervention on top of brushing — not a reason to skip brushing. Professional dental cleanings under anesthesia (COHAT — Comprehensive Oral Health Assessment and Treatment) remain necessary periodically regardless of chew or brushing protocols.
The Bottom Line
For dogs where VOHC-verified plaque control is the primary goal, Greenies Original Regular is the mainstream default and has the strongest clinical-evidence base. For dogs where ingredient-panel transparency matters more than VOHC documentation, Whimzees Stix wins on formulation cleanliness despite lacking the VOHC seal on this specific shape. For cats, Greenies Feline Original is essentially the only mainstream VOHC-accepted option; cats that won’t chew them benefit more from a non-dental premium treat like PureBites Freeze-Dried Chicken (A/95) plus active brushing.
Whatever product you choose, remember that dental chews are a supplement to brushing, not a replacement. Schedule a veterinary dental exam every year starting at age 3 — dental disease in dogs and cats is substantially under-diagnosed because it’s often asymptomatic until advanced, and early detection turns a major procedure into a minor one.
