Can dogs eat seaweed, and why?
Plain, unseasoned seaweed such as nori is fine for dogs in small amounts. Salted or seasoned seaweed snacks are too salty, and dried wild seaweed on beaches can swell in the gut.
Dogs are omnivores, so most of their diet should be a complete, balanced dog food, with treats on top. They cope with a wide range of foods, but rich, fatty or sugary ones can cause stomach upset and, over time, weight gain or pancreatitis.
How to feed seaweed to dogs
- •How much: A small piece of plain, unsalted nori occasionally; avoid seasoned snack seaweed and beach seaweed.
- •How often: An occasional treat, not a daily food. Treats — including fruit and veg — should make up no more than about 10% of a dog’s daily calories.
- •Young pets: Puppies have more delicate tummies and specific growth needs, so introduce any new food in tiny amounts and check with your vet.
- •Preparation: Always wash fresh produce, remove any pips, stones, seeds, peel or tough skin where relevant, and serve it plain — never with salt, sugar, oil, butter or seasoning.
