1. Iodine toxicity: Seaweed is a rich source of iodine, which is essential for thyroid function.

Common neurological signs of toxicity include seizures, running around in circles or running aimlessly, blindness, ataxia (loss of muscle coordination), and changes in behaviour.

4. Salt content: Some types of seaweed can be high in salt, Any food that has high amounts of salt is not good for pooch. Excessive salt can cause a dog’s cells to dehydrate rapidly, excessive salt intake can lead to dehydration, high blood pressure, and other health problems.
