Kelp for Dogs: What It Is and Why It's in Dental Powders

If you have looked at dog dental powders, you have probably seen kelp near the top of the ingredient list. Kelp is a brown seaweed that grows in cold ocean water. Here is what kelp for dogs actually is, why dental products use it, and what to check on the label.

What kelp is

Kelp is a group of large brown seaweeds. Dried and ground, it becomes a fine powder that mixes easily into food. It naturally contains minerals such as iodine, potassium, magnesium and calcium, along with fiber and plant compounds.

Why it shows up in dental powders

One type of brown seaweed, Ascophyllum nodosum, has been studied in dogs for oral health. Researchers have looked at whether giving it daily with food affects the teeth and breath. That research is the reason so many dental powders include seaweed. Results depend on the exact seaweed, the amount and how long it's given, so a study on one product doesn't automatically apply to another.

Iodine: why the amount matters

Kelp is rich in iodine, and dogs need only a small amount of it. Too much iodine over time can affect the thyroid. That is why the amount of kelp per serving matters:

  • Check the label for the amount of kelp per scoop, not just its name in the list.
  • Follow the directions by weight. Giving extra scoops adds extra iodine.
  • Ask your vet first if your dog has a thyroid condition, is on medication, is pregnant or nursing, or eats a diet that already includes seaweed.

How to add kelp to your dog's routine

The easiest way is a complete dental powder that already measures the kelp for you: one scoop on food, every day, alongside brushing. Start with a smaller amount for a few days if your dog has a sensitive stomach.
