Dental Chews Private Label: What the VOHC Seal Actually Means

A product earns VOHC acceptance by completing two sets of clinical trials demonstrating it reduces plaque and/or tartar (calculus) by at least 20% on average compared to a control, evaluated against pre-set VOHC protocols. This is a genuine clinical bar backed by controlled trial data, not a marketing self-assessment or an internal company claim — ask a prospective manufacturer whether a specific dental chew formulation actually holds the VOHC seal, or whether 'dental' is being used as a marketing description without the underlying clinical substantiation behind it, since the two claims carry very different regulatory and reputational risk if challenged by a retailer or regulator later.

If a manufacturer's existing dental chew formulation holds the VOHC seal, any private label version needs to be produced to the identical formulation and process the certification was actually tested on — a private label buyer requesting even minor recipe changes (different flavouring, different shape) should confirm with the manufacturer whether that specific variant still carries the VOHC seal or requires its own re-testing.

A chew can be marketed as supporting dental health through mechanical chewing action (abrasive texture, shape) without holding the VOHC seal — this is a legitimate, lesser claim, but buyers should be precise about which claim their packaging actually makes. Implying VOHC-level clinical efficacy without the seal is a labelling risk worth avoiding deliberately, not by accident.

Dental chew production (extrusion or moulding into specific dental-effective shapes, engineered to create the right abrasive texture and mechanical action against a dog or cat's teeth) is a distinct capability from standard biscuit or jerky treat production — confirm a manufacturer's dental chew production line capacity and MOQ specifically, since it doesn't automatically follow from general treats manufacturing strength.

Dental chews need to balance mechanical dental efficacy with digestibility and choking-risk safety — this is part of why VOHC's clinical trial requirement exists, and why buyers should be cautious about a manufacturer offering a 'dental' product with no clinical backing behind either its efficacy or safety profile at scale, particularly for a private label range carrying your own brand's reputation, where a safety incident traces back to the buyer's own label regardless of which factory actually produced the chew.

Launching private label from an existing VOHC-certified formulation follows a similar timeline to standard private label treats (see our general private label manufacturer guide); developing a new dental chew formulation from scratch and pursuing VOHC certification independently is a much longer, more involved undertaking most private label buyers should not expect to pursue themselves — it's the manufacturer's certification to hold and maintain.

Ask the manufacturer for documentation confirming the specific formulation's current VOHC status directly from VOHC's own published list, rather than relying solely on the manufacturer's own claim — VOHC seals apply to specific, named products, not blanket company-wide certifications.

The most common mistake is assuming any formulation change automatically preserves VOHC status — even a minor shape or flavour tweak can mean the specific tested product no longer matches what's being sold, requiring re-verification. The second is marketing 'dental' claims without checking whether the underlying formulation actually holds the seal versus relying on general mechanical-chewing-action language, which is a real but meaningfully weaker claim. Buyers should get VOHC status confirmed in writing for the exact SKU being launched, not the manufacturer's dental chew range in general, ideally cross-checked directly against VOHC's own published product list rather than a summary document supplied by the factory.

Candora Petcare works with manufacturers whose dental chew formulations hold genuine VOHC certification, verifying that private label variants maintain the certified formulation and helping buyers understand exactly which claims their packaging can accurately make.
