The dental chew section of any pet store contains roughly 40 different products, the vast majority of which carry some variant of the word โdentalโ on the bag. A small subset of those products have actually been tested in controlled studies. Even fewer have demonstrated a meaningful reduction in plaque or tartar in those studies. The Veterinary Oral Health Council (VOHC) Seal of Acceptance is the shortest path through the noise: it identifies products with real clinical evidence behind the dental claim. This guide explains how to read the dental chew category, which products work, which to avoid for safety reasons, and how to build a daily routine that actually helps your dogโs mouth.
Always consult your veterinarian for advice specific to your dog, particularly if you notice bad breath, bleeding gums, loose teeth, or any change in eating behavior. Periodontal disease in dogs is common and often invisible without an oral exam.
Why dog dental health matters
Roughly 80 percent of dogs show clinically significant periodontal disease by age 3 according to American Veterinary Medical Association data. The disease is largely invisible until it is advanced, partly because dogs hide oral pain extremely well and partly because the damage occurs below the gum line where owners cannot see it.
Untreated periodontal disease causes:
- Tooth loosening and eventual loss
- Painful eating that the dog often does not show
- Bacteremia (bacteria entering the bloodstream) that strains the heart, kidneys, and liver
- Reduced quality of life and possibly shortened lifespan
Home dental care meaningfully slows the process. Daily brushing is the gold standard. Dental chews are the most useful adjunct for owners who cannot consistently brush, and a useful add-on for owners who do brush.
What the VOHC seal means
The Veterinary Oral Health Council is an independent body that evaluates pet dental products against a standard protocol. To earn the VOHC Seal of Acceptance, a product must:
- Submit a study protocol approved by the VOHC
- Run a clinical trial against an appropriate control
- Demonstrate a statistically significant reduction in plaque or tartar (the standard cutoff is roughly 15 to 20 percent reduction)
- Pass independent review of the study data
The seal is voluntary. Many manufacturers do not seek it, sometimes because their products would not meet the standard and sometimes because the certification process is expensive. The absence of the seal is not proof that a product does not work, but it is a missing data point. With the seal, you know the product has been tested and produces measurable results. Without it, you are guessing.
The current VOHC list includes treats, chews, dental diets, water additives, and wipes. The product list is updated regularly and is publicly available on the VOHC website.
VOHC-accepted dental chews widely available in 2026
Several VOHC-accepted brands dominate US shelves:
- Greenies. The most widely available VOHC-accepted dental chew. Multiple size categories matched to dog weight. Daily use product.
- Whimzees. Vegetable-based chews in various shapes (Stix, Brushzees, alligators). Daily use product. Suitable for grain-sensitive dogs.
- Virbac VeggieDent. Plant-based chews with a Z shape designed to clean tooth surfaces. Daily use product.
- OraVet Dental Hygiene Chews. Contains delmopinol, an active ingredient that creates a barrier against plaque formation. Daily use product.
- Purina Pro Plan Veterinary Diets DH. A dental diet rather than a chew, but earns VOHC seal for kibble texture and structure that scrapes teeth during chewing.
- Hillโs Prescription Diet t/d. Similar dental diet concept, available through veterinary clinics.
For owners committed to brand-name dental products, any of these provides documented benefit. Within the category, choice often comes down to your dogโs preference, size match, and whether you want a chew, a treat, or a diet.
Chew safety: the rules that matter
The most common dental emergency in dogs involving chews is a tooth fracture, specifically a slab fracture of the upper fourth premolar (the largest cheek tooth). The cause is almost always a chew too hard for the dogโs teeth.
The veterinary thumbnail test: press your thumbnail into the chew. If you cannot make a dent, the chew is too hard. Avoid:
- Cooked bones (any type, including marrow bones)
- Antlers (deer, elk, moose)
- Hooves
- Some hard nylon chews (Nylabone Galileo, for example, and similar dense products)
- Knucklebones from any source
- Ice cubes (yes, they fracture teeth in some dogs)
Safer chews give slightly under pressure: most VOHC-accepted chews, rubber toys designed for chewing (KONG products in appropriate firmness), and some softer rawhide alternatives. Note that traditional rawhide carries its own risks (choking, digestive obstruction) and is not the recommendation it once was.
The other rules:
- Match chew size to your dogโs mouth. A chew small enough to swallow whole is a choking risk.
- Supervise chew sessions, particularly with new products.
- Take the chew away when it becomes small enough to swallow whole (most VOHC chews have specific size guidelines for when to discard the end piece).
Daily chew plus brushing plus professional care
A realistic dog dental routine combining all three pillars:
- Daily: 60 to 90 seconds of brushing with dog-safe enzymatic toothpaste, ideally before the evening meal
- Daily or 3 to 5 times weekly: a VOHC-accepted dental chew
- Continuous: access to fresh water, optionally with a VOHC-accepted water additive
- Every 6 to 12 months: a quick at-home oral check (lift the lips and look for tartar, red gums, or broken teeth)
- Every 12 to 36 months: a professional anesthetic dental cleaning with X-rays, more often for small breeds and brachycephalic breeds
If brushing is genuinely impossible (some dogs cannot tolerate it despite a careful introduction), a daily VOHC chew plus a dental diet plus a water additive is a reasonable home protocol. It does not equal brushing in effectiveness, but it does measurably more than feeding a regular diet alone.
What about dental treats marketed without the VOHC seal?
Many products use words like โtartar controlโ or โdental treatโ without the VOHC seal. Some may have a modest effect, but without independent testing you cannot know which. The category mixes products that work, products that do nothing measurable, and products that may worsen oral health through added sugar or sticky carbohydrates. The practical rule: if dental benefit matters, choose VOHC-accepted.
Calorie load and weight management
Daily dental chews add calories. A single Greenies for a large dog adds roughly 90 to 100 calories, often 6 to 10 percent of daily intake for smaller dogs. To prevent weight gain, reduce the main meal by the chew calories, alternate chew days with non-chew days, or use smaller treat-sized dental products. For dogs with weight problems or specific veterinary diets, talk to your veterinarian before adding daily chews.
Signs your dog needs a vet visit soon
Book an exam if you see any of:
- Bad breath that does not improve with brushing and chews
- Visible tartar at the gum line
- Red or bleeding gums
- A loose or broken tooth
- Facial swelling, especially below the eye
- Dropping food, chewing only on one side, or pawing at the mouth
- Reduced interest in chewing or playing with toys
Periodontal disease and tooth root abscesses progress whether your dog shows pain or not. Chews and home brushing slow disease but do not reverse established problems. Always consult your veterinarian for advice on professional cleanings, and consult your dentist for your own dental questions about how oral health applies in your home with multiple species in the family.
Frequently asked questions
Do dental chews actually replace brushing my dog's teeth?+
No. Even the most effective VOHC-accepted chews are an adjunct, not a replacement for brushing. The Veterinary Oral Health Council criteria require a measurable reduction in plaque or tartar of around 15 to 20 percent in controlled studies, which is meaningful but smaller than the effect of daily brushing. For dogs that refuse brushing entirely, chews are a useful second-best. For everyone else, chews plus brushing is the better routine. Always consult your veterinarian or your dentist if your dog shows signs of dental disease.
What does the VOHC seal actually mean?+
The Veterinary Oral Health Council Seal of Acceptance is awarded only after a product demonstrates a meaningful reduction in plaque or tartar in controlled clinical studies. The standard is independent of the manufacturer and is the most reliable shortcut to a dental chew that works. Many products marketed as 'dental' do not carry the seal and have no clinical evidence to back the claim. Look for the VOHC logo on the packaging.
Are bones, antlers, or hooves good for dog dental health?+
No. They are a leading cause of slab fractures in canine premolars, which are expensive to treat and often require extraction. The guideline used by veterinary dentists is the thumbnail test: if you cannot make a dent in the chew with your thumbnail, it is too hard for your dog's teeth. Cooked bones, antlers, hooves, and some hard nylon chews all fail this test. Choose chews that yield slightly under pressure.
How often should I give my dog a dental chew?+
Most VOHC-accepted chews are designed for daily use, with the daily-use claim being part of the clinical study they ran. Some larger or denser chews are 3 to 5 times weekly. Read the package. Daily chews add calories, so adjust your dog's main meal accordingly to avoid weight gain. For small breeds, the calorie load from a daily chew can be 10 percent or more of daily intake.
Are there dental chews safe for puppies?+
Some, but check the product packaging for a minimum age and weight. Most VOHC-accepted chews are intended for adult dogs because the texture and density assume permanent teeth and full jaw strength. Puppies under 6 months should use puppy-specific dental products. Always consult your veterinarian before introducing chews to a puppy, particularly during teething.
