Why Seaweed Deserves a Spot in Your Pet’s Bowl

Does your dog or cat struggle with excessive eye tearing? Have you ever wondered if there’s a natural ingredient that could help them live longer — or even improve their teeth and gums?

You might be surprised to learn that the answer can be found in a simple, humble weed from the sea — seaweed. 

Now, before you dismiss it as something fit only for sushi rolls, let me tell you — seaweed is a powerful, nutrient-packed food with some remarkable benefits for our pets.

As an aside, I’ve developed a Dental Health Formula that includes a studied brown seaweed known to significantly reduce gingivitis, plaque, and tartar buildup in dogs and cats. If your pet has dental disease, it’s well worth trying.

Seaweed for Dogs and Cats: 7 Important Benefits You Need to Know

Seaweed is one of the most nutrient-dense foods on earth. Different varieties have slightly different benefits, but here’s what they generally offer:

• A powerhouse of 23 essential nutrients including vitamin A, iron, and magnesium

• An excellent source of iodine, crucial for thyroid and metabolism health

• Bioactive compounds like astaxanthin, porphyran, and fucoidan — researched for anti-cancer, antioxidant, and antiviral properties

• Natural prebiotics that boost gut health and immune function

• Heart-healthy minerals and low sodium, keeping cardiovascular health in check

• Omega-3 fatty acids, which support skin, coat, and joint health

7 Key Benefits of Seaweed for Dogs and Cats

1. Cancer Prevention, Immune Support & Longevity

Seaweed, especially kelp, is rich in bioactive compounds that may help suppress the growth of cancer cells. Research shows these compounds can limit tumor cell proliferation and promote cellular repair.

Seaweed nutrients like fucoidan also increase NAD+ levels — supporting energy metabolism and longevity. There’s even a published study discussing seaweed’s anti-aging effects: Anti-aging substances in seaweed.

2. Better Digestion and Gut Health

Seaweed acts as food for the gut. Its high fiber content helps prevent constipation and diarrhea while supporting regular digestion.

It’s also being used for acid reflux — studies show it can reduce acid from backing up into the esophagus, a condition many dogs experience.

And because seaweed is a well-studied prebiotic, it encourages healthy probiotic growth in your pet’s gut.

3. Supports Healthy Thyroid Function

Seaweed is one of nature’s richest sources of iodine, which supports thyroid function — vital for energy, metabolism, and overall well-being.

For dogs, adequate iodine can help prevent weight gain, lethargy, and dull coat issues. However, if you have an older cat, be cautious — senior cats can be prone to hyperthyroidism, so moderation matters.

4. Helps with Excessive Eye Tearing and Staining

Many dog and cat parents have seen success using seaweed to help control eye tearing and stains.

Certain blends of green, brown, and red seaweeds (including sea moss) can reduce inflammation and soothe eye irritation. Over time, they may lessen tear staining by calming the root cause — not just masking the symptom.

5. Improves Skin and Coat Health

A seaweed-rich diet can enhance skin and coat vibrancy. Brown seaweed contains omega fatty acids, fucoxanthin, and fucoidan, which all promote healthy skin and shiny fur.

The antioxidants in seaweed combat oxidative stress, helping reduce dryness, itchiness, and irritation — common issues for many pets.

6. Heart Health

The omega-3s and unique compounds in seaweed — like fucans and polyphenols — help protect the heart.

They may prevent blood clots, reduce inflammation in blood vessels, and support healthy circulation. Plus, minerals like magnesium and potassium maintain a stable heart rhythm.

7. Dental Health Benefits

Seaweed offers powerful dental support. Brown seaweeds produce phlorotannins, compounds with strong antibacterial and antifungal properties.

These target the bacteria responsible for plaque and tartar buildup — improving both teeth and gums.

Seaweed’s minerals, like calcium and magnesium, also strengthen teeth naturally. One study worth reading: Ascophyllum nodosum as a nutrient supporting oral health in dogs and cats.

Caring for Your Pet — Naturally

Seaweed’s benefits go far beyond the ocean. It supports your pet’s immune system, digestion, oral health, and even longevity.

If your dog or cat has excessive tearing, dental issues, or you simply want to support long-term vitality, consider adding seaweed to their daily care routine.
