What should I do if my dog ate salt?

  1. Call your vet or a pet poison line now.
  2. Go to a vet now, even if your dog seems fine, if it ate pure salt, homemade play dough or salt dough, or rock salt, or drank a lot of sea water or brine.
  3. Tell the vet what your dog ate, roughly how much and when, and how much your dog weighs. Small dogs get sick from smaller amounts.
  4. If your dog isn't sick yet, let it drink fresh water while you get help. If it's already unwell, give water only as your vet advises.
  5. Go now if your dog is vomiting, wobbly, trembling or having a seizure.

Don't

  • Don't make your dog vomit unless a vet tells you to.
  • Never use salt or salt water to make a dog vomit.
  • Don't leave salt, play dough or salt dough ornaments where your dog can reach them.

Why

Too much salt at once raises the sodium level in the blood, which harms cells and can make the brain swell. Small dogs and dogs without fresh water to drink are at higher risk.
