All these nutrients are vital to your dog’s health. The vitamins also have anti-inflammatory properties that can help with arthritis in dogs, as well as inflammatory bowel disease (IBD). Seaweeds also have antifungal properties and can be beneficial for dogs with skin allergies or yeast infections. But can dogs eat seaweed without limits?

Nori is a kind of seaweed that is commonly used in human cuisine, particularly sushi. It can be a good option for dogs because it’s low in iodine and doesn’t contain any toxins. Nori can be found at most health food stores, and can be fed to your dog as either a dried or baked sheet.


Rich in iodine, Kelp can be beneficial for canine thyroid health. But beware! Some varieties like hijiki may contain arsenic and other toxins harmful to Fido’s wellbeing if ingested – so watch out for vomiting or diarrhea as possible signs of trouble.


Wakame seaweed is an excellent addition to your dog’s diet – not only does it contain iron and omega-3 fatty acids for overall health, but its high concentration of fucoxanthin can help reduce inflammation. This means that if your pup suffers from arthritis or any other type of inflammatory ailment, this superfood could be a great way to provide relief!


Kombu is a kind of seaweed that contains vitamins K and B9 (folate), as well as minerals like magnesium, zinc, phosphorus, manganese and calcium. It also helps dogs digest starch and contains high levels of iodine to support their thyroid. But don’t overdo it – too much iodine can throw off your dog’s thyroid balance.

Irish Moss

Irish moss seaweed (carrageenan) is rich in vitamins A, B12 and C. It can be helpful for dogs with digestive issues like nausea or vomiting because it has antiemetic properties that help relieve these symptoms. Your dog may also benefit from seaweed’s antibacterial qualities when they have an infection.


Dulse seaweed is particularly high in potassium. This can be helpful for dogs with heart problems or those who are on a low-sodium diet. It also contains iodine, essential for thyroid function, and magnesium, which is beneficial for muscle and nerve function.

Dogs Love Seaweed, But Not All Seaweeds Love Dogs

Keep in mind to never let your dog chew on wild seaweed that just floats about in the water or at the beach! The sun dries out the seaweeds, causing them to shrink. They then act like a sponge in your dog’s stomach after ingesting, causing blockages that could prove fatal. Besides, beach seaweed could have absorbed critters and pollutants that your dog should better stay away from.
