The fiber in seaweed promotes healthy digestion and helps regulate bowel movements.

Seaweed is a natural source of:
- Vitamins A, B, C, and E
- Iron, magnesium, and potassium
- Amino acids for muscle health
Risks of Feeding Seaweed to Dogs
While seaweed is safe for dogs in moderation, there are potential risks:
1. Wild Seaweed Can Be Toxic
Seaweed found on beaches may absorb pollutants, parasites, or harmful bacteria.
2. Too Much Iodine Can Harm the Thyroid
Excess iodine from seaweed can lead to thyroid imbalances, causing weight changes and hormonal issues.
3. Some Seaweed Snacks Contain Harmful Additives
