How DENTAL+ compares with other dog dental powders
Short version: Most leading dog dental powders are built on the same kelp, Ascophyllum nodosum. Some use kelp alone. Others add live probiotics, phosphates, botanicals, flavorings and binders. DENTAL+ sits in between: the same kelp plus one extra, a heat-treated postbiotic, and nothing else.

When another powder might suit you better
- If a VOHC Seal is a must, look for a kelp-only powder that carries it.
- If the lowest cost per day matters most, kelp-only powders are often cheaper, especially for small dogs.
We'd rather tell you that than pretend otherwise.
Why people choose DENTAL+
- Kelp plus a postbiotic. The kelp most dental powders rely on, paired with a heat-treated postbiotic that was tested in dogs.
- Two ingredients, nothing else. No flavorings, yeast, clay or fillers, which matters for dogs with sensitive stomachs or chicken allergies.
- Postbiotic, not live probiotics. Heat-treated, so there's nothing to keep alive in the canister.
- Less per day than many multi-ingredient powders. One canister is 120 scoops: about 4 months for a small dog.
- Taste-tested by Calypso. Our Head of Taste Testing eats it without a second of hesitation.
- Low-waste packaging. Paper tube, home-compostable seaweed pouch and a bamboo scoop.
How to compare any dental powder
- Read the full ingredient list, including inactive ingredients. Flavorings and binders don't always appear on the front of the pack.
- Check the kelp amount per scoop and how many scoops your dog's size needs.
- Work out cost per day: price ÷ number of days the pack lasts at your dog's dose.
- Look for a VOHC Seal if that matters to you.
- Mind the iodine. Kelp is naturally rich in iodine, so check with your vet if your dog has a thyroid condition.
Switching from another dental powder?
Finish your current pack, then start DENTAL+ at your dog's size dose. Most dental powders contain kelp, so don't give two at once. Give it 6–8 weeks of daily use to see a difference.
Not recommended for dogs with hyperthyroidism. Kelp is naturally rich in iodine: if your dog has a thyroid condition, is pregnant or nursing, or takes medication, check with your vet first.
