Can Dogs Eat Seaweed?

Kelp, kombu and other types of seaweed are nutritious superfoods for humans. They’re most often found in sushi and snacks, and they’re a nutrient-rich, flavor-packed food that come with loads of health benefits. 

But as much as we humans love this green treat, what about dogs? If you're wondering, 'can dogs eat seaweed?', the answer is generally yes — but with certain precautions. 

Here's everything you need to know about feeding seaweed to your dog, including the potential risks and benefits.

Most often, yes! Seaweed can be safe for dogs to eat - when it's in the right form. Plain seaweed is rich in nutrients like iodine, magnesium, and omega-3 fatty acids, which can be beneficial for your dog's skin, coat, and overall health. 

Seaweed offers several health benefits when included in a dog's diet:

• Rich in nutrients: Seaweed is high in essential vitamins and minerals like iodine, iron, and magnesium, all of which are crucial for maintaining your dog’s thyroid function and overall health
• Supports healthy skin and coat: The omega-3 fatty acids found in seaweed are excellent for promoting a shiny coat and reducing inflammation
• Aids digestion: Seaweed contains fiber, which can help improve your dog's digestion and regulate bowel movements

Yes, dogs can eat certain types of seaweed snacks, but always make sure to read the label first. Many seaweed snacks designed for humans contain added salt, oils, or seasonings that could be harmful to dogs. 

So should dogs eat seaweed with salt? No — excessive salt can lead to sodium poisoning, which is dangerous and potentially fatal. Symptoms of sodium poisoning include vomiting, diarrhea, and seizures. Instead, choose plain, unsalted seaweed snacks if you decide to share them with your furry friend.

Can dogs eat dried seaweed?

Dried, plain seaweed is another form that can be safe for dogs when given in moderation. 

However, avoid letting your dog eat dried seaweed found on beaches. This can expand in their stomachs and cause blockages and other serious health issues.

Can dogs eat roasted seaweed or seaweed sheets?

Roasted seaweed or seaweed sheets are generally safe for dogs, but again, make sure they don’t contain added salt or flavorings. Roasted seaweed is often served in sheets, much like the kind used to wrap sushi, and can make a crunchy treat for your dog if it's plain and unseasoned.

A small amount of plain seaweed, whether fresh or dried, is generally safe for dogs. But remember - it’s always best to introduce any new food slowly and in moderation to see how your dog reacts. 

If you notice any strong reactions like vomiting or diarrhea, stop feeding the seaweed immediately and consult your vet.

While seaweed can be healthy, it can also pose risks. Wild seaweed, especially the kind found on beaches we mentioned above, can be dangerous if your dog sneaks a taste. It may contain toxic substances, pollutants, or harmful bacteria.

What to do if your dog eats wild seaweed

If your dog accidentally eats wild seaweed while at the beach, monitor them closely for any signs of illness - vomiting, lethargy or diarrhea are all signs to look out for. If you suspect an intestinal blockage due to the seaweed, take your dog to the vet right away.

Don’t choose between your pet and your wallet. With Wag! Compare, you can compare insurance plans from leading providers around the country and find the right plan for your pup. 

The takeaway? Seaweed can be a healthy addition to your dog's diet when given in moderation and in its plain form.

Avoid seaweed with added salt or other harmful ingredients, and never let your dog eat seaweed washed up on beaches. If you're ever in doubt, consult your vet to ensure you're making the best dietary choices for your dog.
