Frenchies vs Plaque & Tartar vs ProDen PlaqueOff Powder: Which Dental Powder for a French Bulldog?
Frenchies vs Plaque & Tartar vs ProDen PlaqueOff Powder: Which Dental Powder for a French Bulldog?
ProDen PlaqueOff Powder is a single ingredient: a brown algae (Ascophyllum nodosum) at 330 mg per dose, two scoops a day for a 25 lb dog. Frenchies vs Plaque & Tartar uses 1,200 mg of the same brown algae per scoop plus spinach, zeolites, flax, chamomile, green tea, rosemary, perilla seed, papain and sodium hexametaphosphate, one scoop a day for a Frenchie up to 25 lb. One scoop of ours carries more algae than two of theirs, plus the rest of the blend.
Quick verdict
Pick PlaqueOff if you want one single ingredient and nothing else.
Pick Frenchies vs Plaque & Tartar if you want more algae per scoop plus the enzyme and mineral blend, one scoop instead of two, and a breed dosing chart. Both are kelp based, so both carry the same caution for dogs with thyroid problems.

Why Frenchie owners pick Frenchies vs Plaque & Tartar
- Nearly four times the algae per scoop. 1,200 mg against 330 mg per dose, so one scoop of ours delivers more kelp than two of theirs.
- The rest of the blend. Sodium hexametaphosphate (the same tartar control mineral used in dental diets), papain, green tea, rosemary, chamomile and zeolites, none of which are in PlaqueOff.
- One scoop, not two. A 25 lb Frenchie gets one scoop a day. PlaqueOff's chart puts the same dog at two.
- Dosing written for the breed. Puppy, up to 25 lb, 25 to 50 lb, over 50 lb, on our label.
- A dated guarantee. 60 days, full jar, refund or discount.
Who should pick which
Choose PlaqueOff for the simplest possible label, especially for a dog with a long list of sensitivities.
Choose Frenchies vs Plaque & Tartar when breath and tartar have not moved on a single-ingredient kelp powder, or you want the enzyme and mineral blend on top of the algae.
Both contain kelp. If your Frenchie has a thyroid condition, ask your vet before either one. Neither replaces a professional cleaning when tartar is already thick.
Questions Frenchie owners ask
Do both powders use the same seaweed?
Yes. Both are built on Ascophyllum nodosum, a brown algae. PlaqueOff is 100% that algae at 330 mg per dose. Frenchies vs Plaque & Tartar uses 1,200 mg per scoop and adds ten other ingredients.
Is a kelp dental powder safe for a French Bulldog with a thyroid problem?
PlaqueOff's own page says it does not recommend the product for dogs with thyroid problems because of iodine, and the same caution applies to any kelp-based powder, including ours. Ask your vet first.
Which works faster on bad breath?
Both companies describe weeks, not days. PlaqueOff says 3 to 8 weeks for noticeable improvement. Our page says fresher breath in 1 to 2 weeks and visible plaque change in 3 to 6. Those are each company's own statements, not head to head tests.
Can I use a dental powder instead of brushing?
A powder works through the saliva all day and reaches teeth a Frenchie will not let you brush, which is why owners use it. It does not replace a vet cleaning when tartar is already built up, and both companies say so.
We compare what each company prints on its own product page. Supplements support normal body functions; they do not treat, cure or prevent disease. Ask your vet before starting any supplement, especially for a dog with a thyroid condition, on medication, pregnant or under 8 weeks.
