Short answer: Pethis Dental Powder is a seaweed, probiotics and enzymes powder, and it does not appear on the Veterinary Oral Health Council (VOHC) accepted-products list. Our pick is Pure Majesty Pets Dog Dental Powder, made in the USA with a certificate of analysis (COA) on every batch.
We sell the powder we recommend, so below is exactly what we compared.
Pethis vs Pure Majesty Pets at a glance (checked October 29, 2026)
| What we compared | Pethis Dental Powder | Pure Majesty Pets Dog Dental Powder |

| Made and tested | We could not confirm where it is made or how it is tested. | Made in the USA. Ingredients and every batch tested in US laboratories, with a COA on every batch. |

Three reasons Pure Majesty Pets is the stronger buy
- You can see exactly what your dog eats. Every one of our 12 ingredients is named with its percentage, so you can judge the formula yourself instead of trusting a headline. With Pethis, there is no formula to read: it does not disclose it.
- A broader formula, not a generic one. Pethis is built on seaweed, probiotics and enzymes. Ours starts with kelp and a GOX/LPO enzyme system, then adds hydroxyapatite (15%), calcium carbonate and calcium lactate (8% each), sodium hexametaphosphate (SHMP, 1%), zinc citrate (0.6%), green tea extract (0.5%), an oral probiotic lysate (0.3%) and inulin (14%), plus pumpkin and pork liver so dogs actually eat it.
- Made in the USA and tested. Our ingredients and every batch are tested in US laboratories, and each batch ships with a certificate of analysis.

What research says about our ingredients (and what it doesn’t)
We chose these ingredients because each has been studied somewhere, and we are explicit about where. No published trial tests our finished powder, and we know of none for Pethis either. Amounts below are per 3 g scoop.
| Ingredient | In our formula | What published research shows | Limit to keep in mind |
|---|---|---|---|
| Kelp (Ascophyllum nodosum) | 8% (about 240 mg) | In a 90-day placebo-controlled trial of 60 small-breed dogs, daily treats containing one specific seaweed product lowered plaque and calculus scores versus placebo. | One proprietary product, manufacturer-funded, on freshly cleaned teeth. Our kelp is not that material. Kelp contains iodine. |
| SHMP | 1% (about 30 mg) | A calcium-binding ingredient studied in beagles as a coating on food, where it reduced calculus. | The results are for a coating, not a powder mixed into the bowl. |
| Glucose oxidase / lactoperoxidase (GOX/LPO) | 0.6% (about 18 mg) | Enzyme systems of this type have been studied in dog chews and in gels. | Not tested in food-topper powders. |
| Green tea extract | 0.5% (about 15 mg) | Green tea catechins have been studied for breath odor in dogs and cats. | That study did not show a plaque or gum benefit. |
| Oral probiotic lysate | 0.3% (about 9 mg) | Heat-treated bacterial ingredients are an early area of dog dental research. | Results are specific to the strain and dose studied. |
| Zinc citrate | 0.6% (about 18 mg) | Used in some human toothpastes. | We know of no published dog trials. |
| Hydroxyapatite | 15% (about 450 mg) | A calcium-phosphate mineral used in human oral-care products. | We found no dog oral-care trials. |
| Calcium carbonate and calcium lactate | 8% each (about 240 mg each) | Calcium sources. | We found no dog oral-health studies. |
| Inulin (chicory root) | 14% (about 420 mg) | A prebiotic fiber. | Dog research is about the gut, not the mouth. |
| Pumpkin and pork liver | 12% and 10% | Fiber and flavor, so dogs accept the powder. | Contains pork. |
What the VOHC seal means
The VOHC does not test products itself. It reviews trial data that a company submits, and it grants its seal to a specific finished product after two controlled studies of at least 28 days with blinded scoring (see the trial requirements). Pethis is not on the accepted-products list. What we can show you is the formula, where it is made and how it is tested.
What a dental powder can and can’t do
- The American Veterinary Dental College calls daily brushing the gold standard, and says accepted products can be used to assist it. A powder works best next to brushing, not instead of it.
- No home powder removes tartar that has already hardened. The kelp trials above started with freshly cleaned teeth. Read plaque versus tartar to see why timing matters, and what a professional cleaning costs if your dog is past that point.
- Pain, bleeding gums, loose teeth or a sudden change in breath need a vet visit, not a supplement.
Talk to your vet before starting any powder if your dog has thyroid disease (kelp contains iodine), a pork allergy (our powder contains pork liver), is pregnant or nursing, or takes medication.
