Salted mackerel
CautionSalt-cured mackerel is a salt product, not a fish fillet. Signs of salt toxicosis in dogs begin at 2-3 g/kg, and a small dog that eats one piece can reach that range.

More about this food
Salted mackerel — jaban godeungeo in Korean kitchens, shiozaba in Japanese ones, and a close relative of salt cod, kippers and salt herring — is cured by packing the split fish in salt. The salt is not a coating; it is driven into the muscle, which is why rinsing or grilling does not take it back out. Curing strength varies enormously between producers and is often not printed anywhere, so nobody can tell you how many grams of salt were in the piece your dog ate. That uncertainty is the actual danger here.
The Merck Veterinary Manual puts clinical signs of sodium chloride toxicosis in dogs at ingestion of 2-3 g/kg, with roughly 4 g/kg as an acute oral lethal dose, and diagnoses salt toxicosis when serum and CSF sodium exceed 160 mEq/L. For a 7 lb (3 kg) dog that lower threshold is 6-9 grams of salt — about a teaspoon and a half.
Signs usually start with vomiting within several hours and can progress to weakness, diarrhea, muscle tremors and seizures. Drinking heavily and urinating more than usual is an early clue.
Two things must not happen at home. Never use salt or salt water to induce vomiting: Pet Poison Helpline warns explicitly that this can create salt poisoning. And never take the water bowl away — but do not let a dog gulp a bowlful either. Merck advises offering fresh water initially in small amounts at frequent intervals, because dropping serum sodium too fast drives water into the brain and causes cerebral edema; clinics correct it deliberately, at 0.5-1.0 mEq/L per hour.
The fine pin bones and the fat are still in there too, and AKC warns that brittle fish bones can perforate the GI tract.
Note how many pieces, how big, when, and your dog's weight, then call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 now.
Frequently asked questions
- Can I soak the salt out and then share it?
- Not reliably. Curing drives salt into the muscle, and soaking or grilling leaves plenty behind. If you want to share fish, cook an unsalted fillet separately and debone it.
- My dog ate a piece and is just drinking a lot. Can I wait?
- Heavy drinking and frequent urination are early signs. Leave water available but offer it in small amounts frequently, and call your veterinarian now. Tremors, stumbling or seizures are an emergency.
- Should I make my dog vomit after eating something very salty?
- No. Pet Poison Helpline warns that salt and salt water should never be used to induce vomiting because of the risk of causing salt poisoning. Let the veterinarian decide on decontamination.
