Seaweed is a type of nutrient-dense algae that grows in oceans, seas, lakes, and rivers all over the world. There are over 10,000 different species of seaweed that come in a rainbow of colors including brown, red, green, and blue. Seaweed provides a wide range of health benefits for humans. It is consumed by humans in many forms, earning it the nickname “vegetable of the sea.” But can dogs also safely enjoy seaweed? This complete guide will cover whether various types of seaweed can be fed to dogs.
What Are the Benefits of Seaweed for Dogs?
When included as part of a balanced diet, seaweed may provide a range of nutritional benefits including:
- Skin and coat health: Seaweed is rich in omega-3 fatty acids EPA and DHA which promote a glossy coat and healthy skin. Seaweed’s antioxidant content also helps fight skin inflammation and allergies.
- Joint support: Fucoidan in some brown algae varieties like kombu have been studied for anti-inflammatory properties that may aid dogs with arthritis. The glycosaminoglycans in seaweed support connective tissues.
- Immune support: Antioxidants like carotenoids, alkaloids and flavonoids in seaweeds help fight disease-causing free radicals and oxidation. Seaweed supports beneficial gut bacteria and overall immunity.
- Digestive/dental health: The high fiber content in seaweed supports digestion and balanced microbiome growth. It can also help clean dogs’ teeth when eating dried seaweed snacks.
- Thyroid function: Iodine is crucial for proper thyroid hormone synthesis and metabolism. Seaweeds, especially kelp, provide abundant iodine for thyroid health.
Can Dogs Eat Seaweed?Types of Seaweed Dogs Can Eat
Now that we understand the nutritional benefits of seaweed let’s explore some specific types of seaweed that are safe and beneficial for dogs to consume:
1. Wakame Seaweed
Wakame seaweed is a healthy food option for dogs. It is rich in vitamins A, B2, B9, C, D, E, and K, as well as calcium, iron, potassium, and omega-3 fatty acids. Wakame seaweed has been proven to be one of the richest plant sources of omega-3 fatty acids, specifically eicosapentaenoic acid (EPA).
Can dogs eat wakame? Yes, the antioxidant-rich wakame seaweed used in miso soup can provide healthy vitamins and minerals for dogs. In moderation, wakame is a good seaweed option.
2. Kelp Seaweed
Kelp seaweed is another safe and nutritious option for dogs. It comprises 25% protein and 2% fat, making it a beneficial addition to a dog’s diet. Kelp contains around sixty different amino acids, vitamins, and minerals, which are vital for maintaining healthy thyroid function and blood circulation in dogs.
Can dogs eat kelp? Yes, in moderation kelp is generally safe for dogs to eat. However, it is essential to note that kelp sourced from US waters may contain high levels of pollutants and toxic chemicals, so it’s best to choose kelp from reputable sources.
3. Nori Seaweed
Can dogs eat nori? Dried nori seaweed sheets are safe for dogs in small amounts. These paper-thin Japanese nori sheets provide protein, vitamins, minerals, and omega-3 fatty acids. Break off tiny strips or squares as a crunchy, low-calorie treat.
However, limiting the amount of nori given to dogs is essential as it may contain trace amounts of harmful chemicals like arsenic and cadmium.
4. Kombu Seaweed
Can dogs eat kombu?This edible kelp is very high in iodine but can be fed to dogs in moderation. It provides glutamic acid for flavor along with fucoidan studied for benefits in joint health.
Kombu Seaweed contains vitamins C, B, D, and E and calcium, iron, magnesium, potassium, silica, and zinc. However, store-bought kombu seaweed pickled in vinegar should be avoided, as it can cause digestive problems in dogs.
Are There Any Risks With Feeding Dogs Seaweed?
While seaweed provides beneficial nutrition, there are some precautions owners should keep in mind:
- Thyroid function: Too much dietary iodine for some dogs may disrupt thyroid function. Use caution when supplementing with high-iodine seaweeds like kelp or kombu, especially if your dog takes thyroid medication.
- Allergies: As with any new food, some dogs may be allergic or sensitive to compounds in seaweed. Start with small amounts and discontinue use if any concerning symptoms develop.
- Contaminants: Only source seaweed from the most reputable places. Seaweed absorbs anything from its growing waters, including heavy metals, chemicals, and bacteria.
- Gastrointestinal upset: Too much dietary fiber from seaweed, especially when introduced quickly, may cause loose stools, gas, or diarrhea. Transition slowly to allow the digestive system to adjust.
- Choking/obstructions: Only feed ground seaweed or very tiny pieces to avoid intestinal blockages. Whole dried seaweed expands when wet and can get lodged.
While moderate seaweed consumption is generally safe for most dogs, there are some risks to be aware of. Consult your vet if any concerning symptoms arise.
How Much Seaweed Can I Safely Feed My Dog?
When first introducing seaweed, start with small amounts and gradually increase over time. Here are some general feeding guidelines depending on the type of seaweed:
- Dried seaweed treats: Only use thin strips or tiny broken up pieces. Limit treats to 1-2 small pieces 1-2x per week for small dogs, and 2-3 pieces for large dogs.
- Powdered seaweed supplement: Follow package instructions based on your dog’s weight. A general starting amount is around 1/4 – 1 teaspoon added to food 1-2x per week.
- Whole roasted seaweed snacks: Break into small bite-sized bits and limit initial intake to 1-2 times per week.
- Fresh cooked seaweed pieces: Chop finely or puree and mix a few teaspoons (5-10g) into food once or twice a week to start.
Gradually increase portion sizes as your dog’s tolerance allows. But even when acclimated, feeding seaweed more than 2-3 times per week may cause adverse effects. Always follow your vet’s advice about appropriate portion sizes.
How to Feed Seaweed to Your Dog Safely
Can Dogs Eat Red Seaweed?
Red seaweed, scientifically known as Rhodophyta, comprises diverse marine algae, including nori and dulse. Humans often enjoy red seaweed in various dishes, but is it suitable for dogs?

Can Dogs Eat Dried Seaweed on the Beach?
While dogs may be curious about dried seaweed they find on the beach, it’s crucial to prevent them from consuming it. Dried seaweed found on the beach can be extremely dangerous and potentially lethal for dogs.
When ingested, dried seaweed can expand in a dog’s digestive system, causing intestinal blockage and potentially leading to stomach rupture. Dried seaweed also contains high salt levels and may be contaminated with hazardous chemicals.
Keeping a close eye on your dog while walking on the beach is essential to avoid any potential risks.
Can Dogs Eat Salted Seaweed?
Salted seaweed, often used as a condiment or seasoning, should be avoided when sharing with your dog. Excessive salt intake can lead to sodium ion poisoning, a severe health issue. Stick to unsalted or lightly seasoned varieties if you choose to offer seaweed.

While plain sushi seaweed is generally safe for dogs, it’s essential to ensure that the sushi does not contain any ingredients, such as soy sauce or wasabi, that can be harmful to them.
What Are Signs of Seaweed Poisoning in Dogs?
If your dog eats too much seaweed, it can potentially cause intestinal blockages, dehydration, and toxicity. Here are some symptoms of seaweed poisoning to watch for:
- Repeated vomiting or regurgitation
- Diarrhea or bloody stool
- Signs of abdominal pain including whining, stretching, or tense belly
- Loss of appetite or refusal to eat
- Increased thirst and urination from dehydration
- Lethargy, restlessness, or weakness
