Why Cats & Dogs Love it
Helps Reduce Plaque & Tartar
Naturally occurring compounds in seaweed can help support oral hygiene, helping to soften plaque build-up and support cleaner teeth as part of your pet's daily dental routine.
Supports Healthy Gums
Good oral health isn't just about teeth. Seaweed provides naturally occurring nutrients that help support healthy gums as part of your pet's everyday dental care.
Freshens Breath Naturally
Supports everyday oral hygiene from within, helping tackle the build-up associated with unpleasant breath and keeping mouths feeling fresher.
Healthy Skin & Shiny Coat
Naturally rich in minerals and trace nutrients, seaweed can also support healthy skin and help maintain a glossy, healthy-looking coat.
Why Seaweed?
Dental support that starts with their diet.
Ascophyllum nodosum · sustainably harvested from the North Atlantic
Unlike brushing, seaweed doesn't need to physically scrub your dog's teeth. When eaten daily, Ascophyllum nodosum is digested and research suggests its naturally occurring compounds can influence the saliva in the mouth, helping create conditions that make it harder for plaque and tartar to build up.
Over time, this can help support cleaner teeth, healthier gums and naturally fresher breath - simply by sprinkling it over their food each day.

Honest answers for a healthier life.
Does seaweed powder help with plaque and tartar on dogs' teeth?
Yes. Ascophyllum nodosum seaweed has been studied for its ability to help reduce the build-up of plaque and tartar when used consistently. Unlike brushing, it doesn't physically scrub the teeth — it is eaten with your pet's food and works through the oral environment to support cleaner teeth over time.
How does seaweed powder work on dogs' teeth?
Once eaten, Ascophyllum nodosum is digested and its naturally occurring compounds can influence the saliva and conditions within the mouth. This can help make it harder for plaque and tartar to build up on the teeth, supporting your pet's dental health from their daily diet.
How long does seaweed powder take to work?
Seaweed powder isn't an overnight teeth cleaner. It works gradually, so consistent daily use is important. Every pet is different and results will depend on their existing dental health, but research into Ascophyllum nodosum has measured improvements over a period of weeks rather than days.
Does seaweed powder help with bad dog breath?
Yes, supporting a cleaner mouth can also help maintain naturally fresher breath. However, persistent or particularly unpleasant breath can be a sign of dental disease, so we recommend speaking to your vet if you are concerned about your pet's oral health.
Can seaweed powder replace brushing my dog's teeth?
No. Regular tooth brushing remains one of the best ways to physically remove plaque from your dog's teeth. Seaweed powder provides additional daily dental support and can be easily sprinkled over food as part of your pet's normal oral-care routine.
Is seaweed powder safe to give every day?
Yes. Logan's Organic Seaweed Powder is designed for daily use when fed according to your pet's weight. It contains just one ingredient — 100% organic Ascophyllum nodosum — with no fillers, additives or artificial ingredients.
Can cats have seaweed powder too?
Yes. Our Organic Seaweed Powder is suitable for both dogs and cats. The recommended daily amount is based on your pet's weight, so simply follow the feeding guide above for the appropriate serving.
Can dogs or cats with thyroid problems have seaweed powder?
Seaweed naturally contains iodine, which can affect thyroid function. If your dog or cat has a diagnosed thyroid condition, is receiving thyroid medication, or you have any concerns about their iodine intake, we recommend speaking to your vet before adding seaweed powder to their diet.
Can seaweed powder remove existing hard tartar?
Seaweed powder is best used as ongoing dental support rather than a replacement for veterinary dental treatment. If your pet already has significant hard tartar, sore or bleeding gums, loose teeth or signs of dental pain, we recommend having their teeth checked by a vet.

“Because your best friend deserves the very best.”
Logan's began with one very special dog — Oscar. Wanting the very best for him inspired us to look more closely at what went into the products we gave our pets, and ultimately led us to create our own.
That same philosophy remains at the heart of Logan's today: carefully selected, straightforward ingredients and supplements we'd be happy to give to our own pets. Oscar's paw remains part of our logo as a reminder of where it all began.
