Aspirin Toxicity in Dogs

  • Hospitalization is often required for definitive care and may require two to five days.
  • Induction of vomiting followed by gastric lavage (pumping the stomach) to remove undigested pills if the dog is examined within four hours of ingestion.
  • Administration of activated charcoal to prevent absorption of aspirin from the stomach.
  • Placement of an intravenous (IV) catheter to administer IV fluids to re-hydrate and to treat or prevent kidney failure.
  • Administration of antacids such as misoprostol (Cytotec®), cimetidine (Tagamet®), famotidine (Pepcid AC®), or sucralfate (Carafate®) to prevent or treat ulceration of the stomach.
  • Administration of antiemetic (anti-vomiting) drugs such as metoclopramide (Reglan®), prochlorperazine (Compazine®) or chlorpromazine (Thorazine®).
  • Home Care

    If accidental ingestion has occurred, remove any remaining pills from the environment. Take your dog to a veterinarian as soon as possible for treatment. If you live more than 30 minutes from the veterinary hospital, call ahead for advice on whether or not to induce vomiting at home prior to transportation.

    If you have been administering aspirin and you note vomiting, black colored stools, pale gums, or loss of appetite, stop giving the aspirin and seek veterinary care as soon as possible.

    Preventative Care

    Do not administer aspirin to dogs unless instructed to do so by a veterinarian. Keep bottles of aspirin out of your pet’s reach, including bottles kept in purses or pocketbooks.

    If your dog’s regular care involves administration of aspirin, give enteric-coated aspirin. Administer aspirin with food to limit stomach upset and never exceed the dose prescribed by your veterinarian. Remember: more is not necessarily better.
