Do Any Natural Chews Clean a Dog's Teeth? What the VOHC List Shows

Chewing a bully stick can help clean the tooth surfaces it touches through natural mechanical abrasion. That is the dental benefit described in our product information. It complements daily brushing and veterinary dental care; it does not replace either or promise a particular clinical result.

Here is how chewing supports a dental routine, what a VOHC Seal tells you, and why a headline percentage cannot replace product-specific evidence.

What the VOHC list actually holds

The Veterinary Oral Health Council maintains a current list of accepted products. Acceptance applies to a named product and its plaque or tartar claim. The list changes, so consult the current register rather than relying on a fixed product count.

The register includes several types of dental products, from diets and chews to toothbrushes and oral-care products. Check whether each named product is accepted for plaque, tartar, or both.

Foodiepaws bully sticks, collagen sticks and tripe sticks are not presented as VOHC-accepted products. That is separate from our description of how natural chewing helps clean teeth. Absence from an accepted-products list does not establish that nobody has tested a product.

What the seal is measured against

The seal isn't a prize for clean teeth. It's a pass mark on one particular trial — and the Council doesn't run that trial. Its own line on this is flat: the VOHC does not test products itself. Manufacturers submit data, and the Council reviews it against a published standard.

That standard is public too. Under the VOHC trial protocol, a chew has to cut the plaque or tartar score by 15% in each trial, average 20% across the two, and clear p<0.05 both times. The control group eats dry food and nothing else. Read that last line twice.

A sealed dental chew has beaten dry food. Never a toothbrush.

A VOHC Seal identifies a product that met the Council's requirements. A product without that seal should not be described as VOHC-accepted; the missing seal alone is not a conclusion about every possible benefit or every study.

How to read our dental benefit wording

Our dental wording describes the physical action of chewing: contact with tooth surfaces can help remove soft buildup and support a regular oral-care routine. We do not turn that into a guaranteed percentage reduction or a claim that a chew treats dental disease.

Keep the two questions separate: what a chew contributes during a supervised session, and whether a product has earned a particular independent seal. Daily brushing and veterinary advice remain part of the routine.

The 85% figure, and where it came from

One number gets quoted in this category as though it settled the question: chewing a bully stick is 85% as effective as brushing. Follow it back and you arrive at one undergraduate paper, written for a General Microbiology course at Rutgers-Camden in 2014.

The project compared bacterial colony counts from mouth swabs before and after each intervention. The reported reductions were: raw bone 79.0%, brushing 70.3%, bully sticks 60.2%, a VeggieDent chew 54.6%.

Now put the spread beside that third number. The bully stick result carries a standard deviation of 29.8 — half the size of the figure itself. The paper's own verdict on all four results is one line: none of the treatments were statistically different, at p=0.330.

So where's the 85%? Divide 60.2 by 70.3 and you land on 85.6%. That last step is ours: the paper never takes it, and nobody quoting the number says where it came from.

It also counted a different thing. A gauze swab picks up whatever will grow on a plate that week. The VOHC trials score plaque and tartar on the teeth. Two measurements, one word.

What chewing does do

Something worth having — and the Council says so on that same page. Its advice to owners runs: the gold standard is brushing, and daily chewing activities can also be effective in maintaining oral health.

That's a mechanical effect, not a medical one. A dried chew is abrasive. Your dog pins one end with a paw and works the other along the same few back teeth, and soft material comes off the faces the chew touches. None of that is your dog's plan. They're trying to finish it.

Which makes duration the variable, not flavor. A stick your dog inhales before you've sat down does none of it — so match the length to your dog, and the thickness to how hard they work. Every bully stick size we make sits together in all bully sticks, from short bites to twelve-inch jumbos, and four checks worth running covers what else to look for.

Where the damage actually happens

Cornell's Riney Canine Health Center puts 80-90% of dogs over three at some component of periodontal disease — and notes it's worse in smaller breeds.

The culprit isn't the brown stuff you can see. Cornell names plaque, an invisible bacterial film laid down above and below the gum line, and puts the real trouble underneath the gums.

No chew reaches under a gum. That's geometry, not an opinion about chews. It's also why daily brushing with a veterinary paste is what Cornell calls the mainstay of a home dental program, and why a bright-looking tooth tells you less than you'd like. In a small breed, the clock starts earlier.

What to watch at chew time

Hardness is the other tooth question, and it isn't this one. Whether a chew can crack a molar has nothing to do with whether it cleans anything, and the honest answer there is less comfortable than most brands let on. What breaks a tooth takes it apart properly.

Then watch the stub. Remove a long stick at three inches, or sooner if it could fit wholly inside your dog's mouth. Trade it for a treat and throw the end out. Stay in the room the whole time: the stub always arrives during the one phone call you had to take.

If your dog has a cracked tooth, a sore mouth, or has just come through a dental cleaning, ask your vet which chews are allowed before any go back in the rotation.

Chews and dental health FAQ

Do bully sticks clean dogs' teeth?

Yes, chewing can help clean the tooth surfaces a bully stick touches. Foodiepaws describes this mechanical action as dental-health support. Keep daily brushing and regular veterinary dental care in the routine; a chew is not a substitute for them, and we do not promise a clinical reduction percentage.

Are dental sticks good for dogs?

An appropriately sized chew can contribute to a dental routine. A VOHC-accepted product has met the Council's requirements for the specific plaque or tartar claim shown on its listing. Formulated dental chews and single-ingredient animal chews both contain calories, so include the amount eaten in the daily treat budget.

If my dog chews every day, do I still need to brush?

Yes. Chewing works on the crown of the tooth, where you can see it, and periodontal disease starts under the gum, where a chew can't go. That's why brushing is the gold standard and everything else is described as helping. If brushing has never been part of your routine, ask your vet to show you the grip at the next visit rather than fighting it alone at home.

A bully stick offers chewing enjoyment and mechanical dental support in one single-ingredient treat. Choose the right size, supervise the session, keep brushing, and remove the small end before it can be swallowed whole.
