Dental chews sit in a gray zone between treat and health product, and Greenies (made by Mars) and Virbac C.E.T. (from the veterinary pharmaceutical company Virbac) are two of the brands most often recommended in vet clinics. Both have products accepted by the Veterinary Oral Health Council (VOHC), the independent group that reviews evidence for plaque and tartar claims. But they work differently and suit different dogs. Here is how they compare.

What VOHC acceptance means
VOHC reviews study data submitted by manufacturers and grants a seal for plaque control, tartar control, or both. It does not mean the chew replaces brushing, which remains the gold standard. Acceptance is specific to the product and sometimes size, so check the current VOHC accepted products list for the exact item you plan to buy.

Safety and choosing the right size
The biggest risk with any dental chew is swallowing a large piece. Always choose the size based on your dog’s weight on the package, and err larger if your dog gulps. Supervise, especially with new chews. Rawhide chews can pose choking or blockage risks for aggressive chewers. Signs such as retching, drooling, vomiting or loss of appetite after a chew need prompt veterinary attention.
Calories
Dental chews carry real calories. A regular-size Greenie or medium VEGGIEDENT can be roughly 70 to 90 kcal, which is a meaningful share of a small dog’s daily needs. Reduce meals slightly if you give one daily.
Allergies and sensitivities
Dogs with suspected poultry or beef sensitivities may do better with plant-based VEGGIEDENT. Dogs that need to avoid wheat may prefer grain-free Greenies or another option. For dogs on an elimination diet, ask your vet before giving any chew.
Building a complete dental routine
Dental disease is one of the most common problems vets see in adult dogs, and small breeds are especially prone. A chew works best as one part of a routine. Brush with a dog toothpaste (never human toothpaste, which may contain xylitol or fluoride at unsuitable levels) several times a week, ideally daily. Add a VOHC-accepted chew, water additive or dental diet if your dog will not tolerate brushing well. Book professional cleanings under anesthesia when your vet recommends them; tartar below the gumline cannot be removed by chewing. Warning signs include persistent bad breath, red or bleeding gums, dropping food, chewing on one side and pawing at the mouth. Any of these should prompt a vet visit, since a painful tooth will not be fixed by a treat.
Which dogs suit which chew
Greenies may suit
- Dogs that like a softer, bendable chew and eat it within a few minutes.
- Owners who want wide retail availability and many size options, from Teenie to Jumbo.
- Puppies and seniors, using the specific Puppy and Aging Care versions.
C.E.T. may suit
- Dogs with suspected animal-protein sensitivities (VEGGIEDENT FR3SH is plant-based).
- Dogs that enjoy a longer chewing session (enzymatic beefhide chews).
- Owners who prefer a brand commonly sold through veterinary clinics.
FAQ
Are Greenies or C.E.T. chews better for tartar?
Both have VOHC-accepted products. Choose based on your dog’s size, chewing style and ingredient needs, and confirm acceptance for the exact product.
Can dental chews replace brushing?
No. They help, but daily brushing and periodic professional cleanings are still needed. See your vet if you notice bad breath, bleeding gums or broken teeth.
Bottom line
Greenies are an easy, widely available daily dental treat with VOHC-accepted versions; Virbac C.E.T. VEGGIEDENT offers a plant-based alternative with a plaque and tartar claim, and the enzyme chews suit dogs that like tougher chewing. Pick the right size, count the calories and keep brushing.
