Walk down the dental aisle and three brands dominate: Greenies, Whimzees, and Virbac C.E.T. All three promise cleaner teeth and fresher breath, but they take quite different routes to get there, and the right one for your dog depends on what you value most. This is the head-to-head comparison to help you decide.

The short version: all three field VOHC-accepted, clinically backed chews, so the real difference is everything else, Greenies on palatability and availability, Virbac C.E.T. on enzymatic action, and Whimzees on natural, grain-free ingredients. Here is how each stacks up.

The Quick Verdict  

• Greenies: the best-known, VOHC-sealed, highly palatable, easy to find. The all-rounder.
• Whimzees: natural, grain-free, limited-ingredient, fun shapes, with VOHC-accepted Brushzees and Toothbrush variants. Best for clean-ingredient owners who still want clinical proof.
• Virbac C.E.T.: vet-favourite, VOHC-sealed, often with an enzymatic coating. Best for proven, clinical-grade plaque control.

If you want one quick rule: all three have VOHC-proven options, so choose Virbac for enzymatic action, Whimzees for natural ingredients, and Greenies for the palatable, easy-to-find all-rounder.

Greenies: The Popular All-Rounder  

Greenies dental chews are the category leader for a reason. They carry the VOHC seal for plaque and tartar control, their chewy-yet-firm texture is designed to clean down to the gumline, and most dogs find them extremely tasty. They come in sizes from Teenie to Large, plus puppy and weight-management versions.

The main considerations are that they are grain-inclusive and moderately calorific, so they suit owners who prioritise proven effectiveness over a minimal ingredient list. For most households, Greenies are the easy, reliable default.

Whimzees: The Natural, Grain-Free Choice  

Whimzees dental chews take the natural route. They are grain-free, made with a short list of vegetable-based ingredients, and come in playful shapes (toothbrush, alligator, hedgehog) whose ridges and texture are designed to scrape away plaque as your dog chews.

Their strength is ingredients: if you want a dental chew without grain, artificial colours, or a long additive list, Whimzees are hard to beat. Importantly, you do not have to trade away clinical proof to get that clean recipe, Whimzees Brushzees and Toothbrush dental treats carry the VOHC seal for plaque and tartar control. Just check that the specific shape and product you buy is the VOHC-listed one, as not every Whimzees product is on the list.

Virbac C.E.T.: The Vet-Recommended Option  

Virbac C.E.T. dental chews are the clinical pick, frequently recommended by veterinarians. Many of their chews include an enzymatic coating (the “C.E.T.” system) that works chemically as well as mechanically to fight the bacteria behind plaque and bad breath, and the relevant products carry the VOHC seal.

If your dog has a real tartar problem or you simply want the most clinically backed option, Virbac C.E.T. is the strongest choice. They are sometimes pricier and less widely stocked than Greenies, but the proven, vet-grade formulation earns its place.

How to Choose  

Match the brand to your priority:

• For proven, easy, crowd-pleasing dental care: Greenies.
• For natural, grain-free, clean ingredients: Whimzees.
• For clinical-grade, vet-recommended plaque control: Virbac C.E.T.

Whichever you pick, size it to your dog, give one a day, and count the calories within the 10 percent treat rule. And remember that no chew replaces the basics: our guide to the best dental chews for dogs covers the wider category, and brushing plus vet check-ups remain the foundation.

Frequently Asked Questions  

Which dental chew is best, Greenies, Whimzees, or Virbac?  

All three are effective and all three field VOHC-accepted chews for plaque and tartar control, including Whimzees Brushzees and Toothbrush dental treats. Whimzees also stands out for natural, grain-free, limited-ingredient recipes. The best choice depends on whether you prioritise enzymatic action, natural ingredients, or palatability and value.

What does the VOHC seal mean?  

The Veterinary Oral Health Council (VOHC) seal means a product has been independently tested and proven to reduce plaque or tartar. Greenies, Virbac C.E.T., and Whimzees (Brushzees and Toothbrush variants) all have chews that carry it, which is the gold standard of evidence for a dental chew. Always check that the specific product you buy is on the VOHC list.

Are Whimzees as effective as Greenies?  

Yes. Whimzees Brushzees and Toothbrush dental treats carry the VOHC seal for plaque and tartar control, just as Greenies do, and they also rely on a tough texture and shape to scrape teeth as your dog chews. On top of that they are a natural, grain-free option, which appeals to owners who prioritise simple ingredients.

Are dental chews enough to clean my dog’s teeth?  

Dental chews help reduce plaque and freshen breath, but they work best alongside regular tooth brushing and vet check-ups. Think of them as a daily supplement to dental care, not a complete replacement for it.

How many dental chews can a dog have a day?  

Most brands recommend one dental chew per day, sized to your dog’s weight. Because they add calories, count them within the 10 percent treat rule and reduce meals slightly if needed.

Conclusion  

Greenies, Whimzees, and Virbac C.E.T. are all genuinely good dental chews, they just serve slightly different owners. Greenies is the proven all-rounder, Whimzees wins on natural ingredients, and Virbac C.E.T. is the clinical, vet-recommended choice.

For most dogs, any VOHC-accepted chew from Greenies, Virbac, or Whimzees gives you the strongest evidence of cleaner teeth, so let the tie-breakers decide: Virbac for enzymatic action, Greenies for palatability, and Whimzees if a natural, grain-free recipe matters most. Pair any of them with brushing and regular check-ups, and your dog’s smile is in good hands. For more on keeping teeth healthy, see our best dental chews for dogs guide.
