Dental Health for Dogs

The evidence for Ascophyllum Nodosum

Ascophyllum nodosum, also known as Norwegian Kelp, has the strongest evidence base of any dietary supplement for canine dental health. A 2018 double-blind RCT published in Frontiers in Veterinary Science found approximately 40 percent reduction in plaque and 20 percent reduction in calculus at 90 days. The product tested holds a VOHC (Veterinary Oral Health Council) Seal of Acceptance. Ascophyllum nodosum works systemically: once digested, its natural compounds enter the saliva to fight bacteria, reduce biofilm and prevent plaque from forming.

This is not the right starting point if...

Your dog has a diagnosed thyroid condition. Ascophyllum nodosum contains iodine and is not suitable for dogs with thyroid disorders. Your dog already has severe periodontal disease requiring surgical extraction. Plaque Control prevents and reduces accumulation but does not treat established infection.

Frequently Asked Questions

Does Petz Park Plaque Control reduce plaque?

The active ingredient Ascophyllum nodosum was studied in a double-blind RCT showing approximately 40 percent plaque reduction and 20 percent calculus reduction at 90 days.

How long until I see results?

The clinical evidence is based on 90 days of consistent use. Some improvement in breath may be noticeable sooner.

Does it replace toothbrushing?

It is not a replacement for mechanical cleaning but is a significant addition for dogs that do not tolerate brushing. Used consistently, it reduces the rate of plaque and tartar accumulation.

Is it safe for dogs with thyroid conditions?

No. Plaque Control for Dogs is not suitable for dogs with thyroid disorders due to its iodine content. Consult your vet if your dog has a known thyroid issue.

My dog already has tartar. Will this help?

Plaque Control is most effective for prevention and slowing accumulation. Existing tartar typically requires professional dental cleaning under anaesthesia. Start Plaque Control after a professional clean for best results.

Can I use this alongside a dental chew or toothpaste?

Yes. Multiple complementary approaches produce better outcomes than any single method alone.

At what age should I start?

From when your puppy has their adult teeth, typically around 6 months. Starting early prevents accumulation from establishing.

How does it work when mixed into food?

Ascophyllum nodosum is absorbed through digestion and excreted into saliva, where it inhibits the bacterial enzymes responsible for plaque formation. The mechanism is systemic, not topical.
