Is Seaweed Safe for Dogs?

Dogs can eat seaweed.


Seaweed is safe for dogs to eat! There are several benefits to adding this to your pup’s diet. You may want to learn more about it because you eat it, or maybe you hope it will help with some health issues your doggie is having. How do you feed them this healthy boost? What kind isn’t safe? Keep reading to learn the benefits and risks of feeding your pup seaweed.

Benefits of Feeding Your Dog Seaweed

Antioxidants are a term you’re probably acquainted with, but you might not know what they are or do. It’s crucial to comprehend oxidation first. Oxidation happens when an apple starts to turn brown after being chopped into smaller pieces. 

Rust on automobiles is another illustration. Health depends on this chemical process. This is how dogs’ bodies digest dog food to absorb nutrients when they eat it. Let’s see the other benefits seaweed offers dogs.


Iodine is necessary. It controls thyroid function, promotes a healthy metabolism, helps with growth and development, guards against chronic illnesses like cancer, and promotes your dog’s cognitive health. Unfortunately, iodine insufficiency affects many dogs, even those fed only raw meat. 

Iodine is a trace mineral that’s vital for the production of both thyroid hormones. These hormones are essential for the early growth and development of most organs, particularly the brain. They also control the majority of cells’ metabolic processes. 

Insufficient consumption of iodine-rich foods results in the inadequate generation of these hormones. The heart, liver, kidneys, developing brain of your dog, and muscle tissue are negatively impacted by the decreased thyroid hormone production.


Riboflavin is necessary for several enzymes in your dog’s body to metabolize protein, carbs, and fat into energy. Your dog would not be able to digest these without riboflavin. Riboflavin is essential for the growth and repair of DNA. 

Simply said, DNA helps preserve your dog’s overall health by repairing wounds, delaying the aging process, and even contributing to preventing diseases like cancer. As you can see, riboflavin is crucial for your dog’s health. 

A riboflavin deficiency, often known as a vitamin B2 deficiency, might develop if your dog doesn’t get enough. A severe Vitamin B2 deficiency may result in death. Because of this, dietary guidelines for dogs call for significant levels of riboflavin.

Omega 3

One of the benefits of omega-6 and omega-3 fatty acids for dogs that is most frequently highlighted is an improvement in the state of the skin and coat. Dogs with dry, itchy skin and dull coats should consume these fats in sufficient amounts. 

Dogs with allergic skin disorders may also benefit from omega-3 fatty acids. Using omega-3 fatty acids to reduce inflammation is advantageous for the joints of dogs. For dogs with arthritis, decreased inflammation translates to more movement and less pain. 

It can assist dogs with joint problems, but it may also be advantageous for limiting the harm that inflammation causes joints, potentially lowering the severity of upcoming joint difficulties. Because of this, several dog meals designed to support joint health contain more omega-3 fatty acids than typical dog food.


One of the vitamins necessary for your dog’s healthy growth is vitamin B12. Vitamin B12 is a vital component of the dog’s diet because of its nutritional qualities. It is essential for the neurological system, cell growth, protein synthesis, fat and carbohydrate metabolism, and the production of red blood cells. Your dog depends on a healthy diet to provide it with the vitamin B12 intake because mammals’ bodies can’t make it.

The Risks of Feeding Your Pup Seaweed


Make sure your dog doesn’t eat wild seaweed.


If you give your dog healthy seaweed treats, they might get a taste for it, which could be harmful if you take your dog to the beach. It’s crucial never to let your dog consume beach-found seaweed. Your dog should avoid the wild seaweed frequently seen on beaches during the summer. 

It’s recommended to keep your dog on a leash while you explore the beach so you can stop them from eating seaweed or other dangerous plants. Wild seaweed shrinks and dries out in the summer heat.  It will absorb water and expand in your dog’s digestive tract, resulting in obstructions that may be fatal if consumed by your dog. 

Additionally, the seaweed you find on the shore can be contaminated or home to pests you shouldn’t let your dog eat. Get in touch with a veterinarian if your dog has consumed seaweed from the beach as soon as possible. Before distributing any commercial seaweed goods, make sure to verify the ingredients for additional seasonings. 

How To Feed Your Pup Seaweed

The most straightforward approach to incorporating seaweed into your dog’s diet is to sprinkle a seaweed supplement on top of their food. Seaweed is a delectable treat that’s also healthy for your dog, even though it may seem salty. Seaweed is surprisingly low in sodium. You only need to watch out for wild seaweed, and you should watch how much of it you give your dog.

Avoid Seasonings

Sharing basic seaweed snacks with your dog is safe, but foods that have been seasoned with garlic or onions are actively discouraged. The best action is to regulate your dog’s consumption because too much of any food might upset their digestive system and result in vomiting and diarrhea. Arsenic and mercury are in trace concentrations in kelp supplements and nori, respectively. It’s recommended to restrict your dog’s intake of seaweed due to these.


Giving your dog seaweed can help them get several health boosts. It can help their joints, skin, and fur. This is because it has omega 3s. It can also give your doggie an antioxidant boost and is an excellent source of iodine. 

Adding it to their diet is simple; you just get ground seaweed and sprinkle it on their food. The only risk to dogs eating seaweed is the kind found on the beach. If you know someone who enjoys seaweed snacks, let them know they can get some for their dogs too! Check out the other fun articles about what dogs can eat down below; your pup will thank you!
