Can Dogs Eat Seaweed?

• Not a substitute for professional veterinary help.

We enjoy the briny taste of seaweed in wafer snacks, soups, sushi, and other tasty foods. But is the savory taste of seaweed just for you to enjoy, or can our pups partake? Yes, dogs can eat seaweed. Experts say certain types of seaweed can be a healthy snack for dogs in moderation – including plain, unseasoned nori, dulse, Irish moss, and more.

Learn more about dog-safe varieties of seaweed below, and discover the potential pros of adding it to your dog’s diet.

Is Seaweed Nutritious for Dogs?

“Seaweed is generally safe and can be very nutritious for dogs,” says Kathryn Dench, holistic veterinarian and chief scientific officer at Paw Origins. Several types of seaweed include vitamins, minerals, healthy fatty acids, and other nutrients.

Some potential benefits dogs may experience from eating seaweed include the following.

1. Promotes thyroid health. Many types of seaweed contain iodine, an essential nutrient for dogs. “Iodine helps maintain a healthy metabolism and supports proper thyroid hormone production,” says Patrick Wilson, a veterinarian with Well Pet.
2. Anti-inflammatory effects. Many seaweeds contain omega-fatty acids, which may possess anti-inflammatory properties.
3. Skin & coat health. Dr. Wilson says the fatty acids in some seaweeds may also promote healthy skin and a shinier coat.
4. Immune boost. Many seaweeds contain vitamin C, which Dr. Wilson says may support a dog’s immune system.
5. Joint support. “Certain types of seaweed contain glucosamine and chondroitin. Dr. Wilson says these nutrients support joint health and help mobility, especially for senior dogs.
6. Bone health. Dr. Wilson says many seaweeds can contain vitamin K, an important nutrient for blood and bone health.

How Much Seaweed Can Dogs Eat?

Choose seaweed products specifically designed for pets to help your dog enjoy seaweed safely. Dr. Wilson says this ensures they have dog-safe nutrient levels and don’t contain any added salt.

For the serving size, follow the directions on the packaging or consult your vet for more personalized advice.

What Are the Risks of Dogs Eating Seaweed?

While seaweed is good for dogs in moderation, some types are high in sodium and iodine. Dr. Wilson says if these are too high, they can harm your pup. Examples of high-iodine seaweeds include kelp, bladderwrack, and certain red and green varieties.

Additionally, Dr. Wilson adds that seaweed may be difficult for some dogs to digest and could potentially cause diarrhea or constipation. Many seaweed foods designed for humans can contain seasonings or salt. Dr. Dench suggests avoiding seasoned or salted seaweed products since dogs are more sensitive to sodium than humans.

What Other Veggies Are Safe for Dogs to Eat?

Want to discover other ways to help your dog eat their vegetables? The following green vegetables can also make a safe and nutritious addition to a dog’s diet. As always, get permission from your vet first.

• Broccoli. “Broccoli is a good source of fiber, vitamins C and K, and folate,” says Nicole Savageau, a veterinarian with The Vets.
• Brussels sprouts. Brussels sprouts are non-toxic to dogs and contain vitamins A, C, and K and fiber. Dr. Dench says it’s safe for many dogs to eat cooked Brussels sprouts in small portions.
• Spinach. Spinach contains nutrients like calcium, iron, magnesium, and potassium.
• Peas. “Peas are a good source of protein, fiber, and vitamins A, C, and K,” Dr. Savageau says. “They are often used as a plant-based protein source in dog foods.”
• Green beans. Dr. Savageau says green beans are low in calories and can add bulk and fiber to a dog’s dinner.
• Celery. “Celery contains vitamins such as A, C, and K, as well as minerals like potassium and folate,” says Dr. Wilson. It can make a safe dog snack if it’s de-stringed and in bite-sized pieces.

Takeaway

Dr. Dench says seaweed is a healthy addition to a dog’s diet in moderation. However, many seaweed foods designed for humans contain salt or seasonings that dogs should avoid. So, double-check the packaging for seasonings before tossing your dog a seaweed roll on sushi night or sprinkling seaweed on top of their food.

If you want to introduce seaweed to your dog’s diet, Dr. Wilson suggests choosing dog-specific products for safety. One of the most common is Canident, a seaweed blend to help clean your dog’s teeth.

Whatever seaweed product you choose, follow the serving size suggestions or your vet’s recommendation.
