Miyeok (wakame seaweed)

The danger in miyeok is volume, not chemistry. Dried wakame rehydrates to roughly 8 to 10 times its dry bulk, and that expansion does not care whether it happens in a mixing bowl or in a dog's stomach. It is the same mechanical problem as raw bread dough: what goes down looking like a small handful keeps growing as it pulls in fluid. In a small dog, a bag of dried seaweed off a low shelf is an emergency in its own right. There is no chemical dose threshold to reason from here, so do not try to estimate one. Swelling generally progresses over the first 1 to 3 hours; an obstruction picture develops across 12 to 72 hours. Watch for a visibly distended abdomen, unproductive retching, vomiting, pain on belly palpation, refusal to eat, no stool, and lethargy — that cluster means obstruction until a vet proves otherwise. If you know your dog ate dried wakame, call your veterinarian, an emergency hospital, or the ASPCA Animal Poison Control Center at (888) 426-4435 immediately, before symptoms start. Do not induce vomiting at home. Bringing an already-swelling mass back up risks lodging it in the esophagus or aspirating it, and whether to decontaminate, image, or scope is a veterinary decision. Bring the bag and the time of ingestion. Cooked wakame dishes fail for a separate reason. Korean miyeok-guk — the birthday and postpartum soup — is built on soup soy sauce, salt, garlic, sesame oil and beef. Japanese-style seaweed salad and miso soup follow the same pattern with soy, sugar and salt. Garlic damages canine red blood cells and soy sauce is a concentrated sodium load, so the broth is not a healthy shortcut just because seaweed is in it. If you want to share at all, the only reasonable form is a very small amount of plain, fully rehydrated, unseasoned wakame, rarely. Seaweed is a dense iodine source, so clear even that with your vet for a dog on thyroid medication — and keep the dry bag out of reach.
