Description

ProDen PlaqueOff Powder for Cats & Dogs (60g) – Plaque Remover Made with Organic Seaweed: Clinically Proven by the VOHC to Reduce Tartar, Plaque, and Bad Breath.

Why Choose ProDen PlaqueOff® Seaweed Powder?

  • Unlike other seaweed dental powders, ours is organic and made from a unique subvariety of Scandinavian Ascophyllum nodosum seaweed (A.N ProDen®).

  • This Scandinavian variety is the only type of seaweed clinically proven by the VOHC (Veterinary Oral Health Council) to reduce plaque, tartar & bad breath.

  • Easy to use - simply mix the powder into your cat’s wet or dry food daily using the included scoop. Results are typically visible within 3-8 weeks of continued use.

  • Trusted for over 25 years as the original pet oral hygiene solution, and recommended by veterinarians worldwide.

  • GMP+ certified and sustainably harvested from the clean Scandinavian coastline, ensuring exceptional purity.

  • Made from 100% pure seaweed powder, ProDen PlaqueOff® powder is naturally hypoallergenic with no additives, preservatives, or fillers.

  • How does it work? Once digested, the active compounds in A.N ProDen® seaweed are released through saliva, coating the teeth and softening stubborn plaque and tartar, helping to reach areas a toothbrush may miss.

  • A single 60g pot can last up to 6 months, depending on your pet’s weight. Each scoop contains 330 mg*.

Usage & Suitability

Suitable for: Cats and dogs. (A cat-only 40g version formulated with tasty selenised yeast is available for fussier cats.)

Not recommended for: Pets with hyperthyroidism due to seaweed’s naturally high iodine content.

Top Tip: If your pet has a sensitive stomach, introduce gradually. Seaweed is high in fibre, and a sudden increase may cause digestive upset.

Good product
Verified Purchase

By Chris Lawmon on 31 May 2026

Have used this before. It’s a good product, seems to work after a few months results are good. Introduce small amounts before going to the recommended amount, it initially caused our dogs upset stomachs, all ok after a few days on reduced amount

PlaqueOff powder
Verified Purchase

By Janice Williams on 27 April 2026

Although I brush my dog's teeth, this does not remove the plaque. I have been using PlaqueOff for a few weeks and there is a definite improvement with my dog's teeth, especially noticeable in the back teeth which were very stained. Hopefully there will be further improvement.

Q & A

Below are some recent questions we've received regarding ProDen PlaqueOff Powder for Cats & Dogs, including answers from our team.

Plaque remover

Harvey

At two scoops per feed how long will 60g last

  • VioVet Staff

A 60g container of Plaque Off for Dogs and Cats, used at two scoops per feeding, will typically last around 1-2 months depending on the size of the scoop and how often your pet is fed per day.

Karen Preston

How many scoops in 420g pack?

PlaqueOff suitable in hypothyroidism

Tara

My cocker spaniel has Thyforon 200mcg medication for hypothyroidism. The condition has long been under control. She is aged nine and has tartar build-up on her teeth. Is it ok to use PlaqueOff ?

  • VioVet Staff

Plaque Off does contain seaweed which is high in iodine. Iodine is used by the thyroid gland to function and so increased iodine theoretically could increase it's productivity. Hypothyroidism is an underactive thyroid gland though so this should actully work in your dog's favour, however to be safe I recommend double checking with your vet if this is suitable.

Bladder stones

Yvonne Grey

  • VioVet customer since 2020
  • From: Durham, United Kingdom

my dog had bladder stones removed a year ago is still on special diet food is it okay to use Plaque off

  • VioVet Staff

This depends on the specific type of bladder stone your pet is affected by. It is recommended you run the use of this product past your vet to be certain as they will be aware of the type of stone involved.

31 January 2022 at 6:28pm

Side Effects

PhilH

Are there any known side effects? My Shih Tzu seems to develop Diarrhea after about 4 days of use.

  • VioVet Staff

Plaque Off is a supplement and so is classed to food. There are no listed side effects for the product, but like any food it can cause a reaction if your dog is intolerant/allergic to one of the ingredients. If you are seeing diarrhoea then I advise stopping the supplement. If the diarrhoea also stops then, if safe, you can restart the supplement to determine if this was caused by a coincidental scavenging event or the Plaque Off itself.

Is plaque off ok for pancreatatic dog.

Lesley Jane

  • VioVet customer since 2020
  • From: Devon, United Kingdom

I've got a pancreatatic dog on Zitac, Nutraflora probiotics and Nutraquin+ joint aid will Plauee Off be ok to use. Thank you

  • VioVet Staff

None of the ingredients within Plaque Off are contraindicated for a dog with pancreatitis. However it is best to limit any dietary changes if your dog has the condition. Particularly sensitive dogs can be set off even by the slightest changes, it is best running the use of the supplement past your vet to be safe.

How long does it last?

Aimee

How many scoops are in a 60g tub? If using 1 scoop per day how many days would this last. Thanks

  • VioVet Staff

One level scoop of this product is 1/3 of a gram. If giving 1 scoop per day then 1 x 60g tub should last 180 days.

Plaque Off suitable for kibble

Victoria Turner

  • VioVet customer since 2021
  • From: Greater Manchester, United Kingdom

Would you recommend using Plaque Off on kibble, or would it be more effective when used with wet food?

  • VioVet Staff

Plaque off works well with wet or dry food. You may find your pets general dental health is better on kibble though as this is less likely to get stuck within the teeth and cause plaque build up.

11 February 2021 at 10:26pm

Is this suitable for a dog with Pancreatitis?

Jes Edwards

Is this suitable for a whippet with Pancreatitis? If not what would you recommend for him? His big back teeth have tartare buildup because he doesn’t chew with them. His frontal teeth are perfect.

  • VioVet Staff

Dogs with pancreatitis can be very prone to repeat episodes with dietary changes. This varies between patients and some are fine with additions to the diet, but if wanting to be safe I would avoid any additions to the diet. This includes safe supplements like Plaque off.
If you are wanting to help your dog's teeth then brushing is ideal. I recommend reading our blog 'Why do vets care about our pet's teeth?' for more information.

Hypoallergenic

Laura Wloskowicz

  • VioVet customer since 2020
  • From: Bedfordshire, United Kingdom

Is this product suitable for a cat on a hypoallergenic diet (Hills zd)

  • VioVet Staff

Plaque off just contains Seaweed and Brewers Yeast which are both extremely unlikely to set off an allergic reaction, however they are not guaranteed not to set one off. If your cat is currently on a food trial then I would avoid the product but if they have been stable for a while then you can try Plaque off. If your cat is allergic to seaweed in particular then you may see signs of the allergy when starting it, if this occurs then stop it immediately.
If your pet is on a prescription diet like Hills Z/D then it is always best to run any additions like Plaque off past your vet first.
