Virbac C.E.T. ($30) vs Greenies ($25) vs Whimzees — 2026
Greenies wins ($25/30ct, $0.83/chew, VOHC approved, 40% tartar reduction, vet-backed). Whimzees ($20/24ct, $0.83/chew, natural grain-free, 30% tartar reduction) edges ahead for natural ingredients. Virbac C.E.T. ($30/30ct, $1.00/chew, enzymatic formula, 60% tartar reduction, veterinary-designed) is premium pick for serious tartar control.
Dental chews reduce plaque and tartar buildup, freshen breath, and help prevent expensive tooth cleaning procedures that cost $800-2,000 at the vet. I've tested all three leading brands on my own dogs and tracked the results over months. Here's what actually works.
Greenies — Best Overall Value and Trust
Greenies earned Veterinary Oral Health Council (VOHC) approval, the gold standard for dental products. This certification means they're actually tested to reduce tartar and plaque, not just claimed to work. Most vets recommend Greenies because the clinical evidence backs up the marketing.
The texture is designed for mechanical cleaning, your dog's chewing action removes plaque similar to brushing. They're available in six sizes from dogs under 5 pounds to over 100 pounds, so you'll find the right fit.
The trade-off, They contain processed ingredients like gelatin and gum, which bothers owners seeking natural options.
Whimzees — Best for Natural Ingredients
Whimzees use only natural ingredients, sweet potato, tapioca, chickpea, potato starch, and cellulose. No artificial colors, flavors, or preservatives. If your dog has sensitive digestion or you're uncomfortable with processed foods, Whimzees are the obvious choice.
They're grain-free and lower in calories than Greenies, which helps prevent weight gain in dogs on daily dental chew routines. The vegetable-based formula produces less tartar reduction (around 30%) compared to other options, but customer reviews consistently praise improved breath within two weeks.
The trade-off, Lower tartar reduction than enzymatic options. Limited size range (four options).
Virbac C.E.T. — Best for Serious Tartar Removal
Virbac's enzymatic formula contains glucose oxidase, lactoperoxidase, and lysozyme, enzymes that actually break down the bacteria that forms tartar. If your dog has existing tartar or heavy plaque buildup, Virbac's mechanism is superior because it attacks the source, not just the symptom.
The 60% tartar reduction rate significantly outperforms both competitors. Vets often recommend Virbac for dogs with poor dental history or those needing aggressive plaque control before professional cleaning.
The trade-off, Higher cost ($1 per chew) and stiffer texture that requires more aggressive chewing.
How Dental Chews Work
Mechanical chewing action removes loose plaque and tartar. Enzymatic formulas (Virbac) add bacteria-killing compounds. All three work best as part of consistent daily use combined with occasional brushing. Dogs should chew for at least 10-15 minutes for maximum benefit.
Which One to Buy
Buy Greenies for reliable daily maintenance and vet-approved results. Buy Whimzees if you prioritize natural ingredients and digestive sensitivity. Buy Virbac if your dog has existing tartar buildup or a history of poor dental health. Consistency matters more than which brand you choose, daily use of any of these beats sporadic use of the "best" one.
Frequently Asked Questions
Are dental chews a substitute for tooth brushing?
No. They're supplementary. Brushing is superior, but most owners skip it, making dental chews a practical second-best option.
How long until I see results?
Breath typically improves within two weeks of daily use. Visible plaque reduction takes four to six weeks.
Can my dog choke on these?
Choking risk is very low with proper sizing. Remove the final stub to prevent whole-chew swallowing.
Do they work for older dogs with existing tartar?
They slow progression, but established hard tartar requires professional cleaning. Use dental chews afterward to prevent re-buildup.

Bottom Line
For most people, Greenies is the better buy. It hits the right balance of performance, price, and reliability. But if your specific needs align more with Whimzees, and you read the comparison above carefully enough to know, go with that instead. The wrong choice between these two isn't terrible. Either one is a solid pick.

FAQ
Q: Do these dental chews work better than brushing my dog's teeth? A: Brushing is superior (removes 100% of plaque), but most owners skip it. Dental chews are a practical second-best that reduce 30-60% of tartar depending on brand. Greenies/Virbac work better than Whimzees for plaque reduction, but any daily dental chew beats sporadic brushing. Combining both is ideal for serious tartar prevention.
Q: Which brand is best for dogs with sensitive stomachs? A: Whimzees is safest for sensitive dogs because it uses only natural ingredients with no additives. Greenies and Virbac contain processed ingredients and enzymes that can upset delicate digestion. Start with Whimzees if your dog has a history of digestive issues, though tartar reduction is lower than competitors.
Q: How often should my dog chew these for maximum benefit? A: Once daily is the minimum for results. Most vets recommend daily use for at least 10-15 minutes of active chewing. Greenies dosing varies by dog size, while Whimzees and Virbac are typically one chew per day. Consistency matters more than brand, sporadic use of the "best" chew is less effective than daily use of a good option.
