Kelp Vs. seaweed

Kelp is a seaweed. But are all seaweeds kelp? Definitely not! Then what is the difference between regular seaweed and kelp?

Seaweed is a generic term used for almost all kinds of sea vegetation. They range from small plants to giant trees underwater. They also vary in color and texture. On the other hand, kelp is a large-sized seaweed, often brown in color. It grows up to 260 feet.

Kelp is only found in seawater and oceans. You will never find kelp in freshwater bodies like lakes and rivers. They grow along rocky shorelines – the constant movement of water is why they are packed with so many nutrients.

That doesn’t make other seaweed any less beneficial. Seaweeds like nori and kombu are equally popular among seafood enthusiasts. But kelp has the benefit of having extra iodine in it that is super helpful for both humans and dogs.

While kelp tastes salty, it contains very little sodium. But since kelp is always found in the salty oceans, experts always recommend commercially dried kelp over fresh kelp. This is because wild kelp has more salt content and is not really healthy either for you or your dog.

Benefits of kelp for dogs

Following are some of the key benefits of feeding kelp to your dog:

  1. The presence of iodine in kelp helps maintain activities in the thyroid, pituitary, and adrenal glands. It also prevents hyperthyroidism in dogs which is equivalent to goiter in humans.
  2. Minerals and vitamins in kelp may help reduce dental issues in dogs. The natural enzymes break down tartar and plaque, resulting in healthy teeth and gums.
  3. Kelp boosts skin health and reduces itchiness. It repels fleas and lice off of a dog’s fur. With better skin, the coat also gets its natural sheen and softness.
  4. The presence of natural amino acids speeds up the wear and tear in a dog’s body. Japanese always believed that eating seaweed maintains tissue repair, which grants a longer and healthy life.
  5. High iron and calcium levels in kelp prevent iron deficiency and improve blood flow in the body. Older dogs who may suffer from arthritis and anemia may get the best from consuming kelp supplements.
  6. It improves gut health due to the presence of probiotics. These probiotics reduce pathogens in the digestive tract and control good bacteria’s growth in the gut.

The dos and don’ts of feeding your dog kelp

Your dog can eat kelp, that’s for sure. And you can be a happy owner now that you know how beneficial is kelp for your dog. But then again, as a responsible owner, you must be cautious with everything.


  1. Always give dried kelp to your dog. Break the pieces into smaller ones so that they can be digested easily. It would actually be best to powder dried kelp on your dog’s regular meal. 2 teaspoons for a large adult dog are more than enough.
  2. Get good-quality dried kelp from an authentic place.
  3. Ask your dog’s vet before feeding kelp. They know your dog better than anyone else.
  4. Rush to a vet if you see adverse symptoms in your dog after feeding them kelp. The symptoms may include runny nose, vomiting, diarrhea, and loss of appetite.


  1. Avoid feeding loads of kelp to your dog every day. Kelp is excellent for your dog’s health, but you still have to feed them other food too.
  2. Never give whole pieces of kelp to dogs. It will be hard to chew for your dog, and the chances are that the kelp will expand in the stomach, resulting in aches and vomits.
  3. Once your dog starts liking kelp, they’ll also like wild kelp on the beach as well. You must keep your dog away from eating the kelp from the beach. Not only is it polluted, but it is also high in salts and will make your dog sick.
