The decontamination sequence for a dog with known or suspected toxin ingestion proceeds in order: stabilize the patient, assess eligibility for decontamination, perform gastrointestinal (GI) decontamination if appropriate, then provide supportive care and monitoring.
Patient stability and clinical status determine whether decontamination is safe to perform before any intervention begins. The route of exposure and substance type must be evaluated to confirm that decontamination is appropriate and unlikely to cause additional harm. MSD Vet Manuals A dog already showing neurologic signs, seizure activity, or impaired consciousness is not a candidate for emesis or oral activated charcoal administration due to the risk of aspiration. Journal of the…
For asymptomatic dogs with known or strongly suspected ingestion, emesis induction is appropriate within 1 hour of exposure. Emesis should not be performed once clinical signs are present, as this risks aspiration of gastric contents and may precipitate seizure activity. Journal of the… Gastric lavage under general anesthesia with a protected airway is an alternative decontamination route when emesis is contraindicated. Journal of the…
Activated charcoal with a cathartic reduces GI absorption of many toxins when administered within 1 hour of ingestion. For amanitin (Amanita mushroom) toxicosis specifically, activated charcoal with sorbitol (if diarrhea is absent) is used after gastric evacuation, and both oral and rectal administration routes are appropriate; this approach may also interrupt enterohepatic recirculation of the toxin. MSD Vet Manuals Activated charcoal should not be given to patients with impaired neurologic function due to aspiration risk. Journal of the…
For topical exposures, decontamination is achieved by thorough washing with liquid degreasing dish soap and water; clipping of hair or wool may be necessary. MSD Vet Manuals For chemical warfare agent exposures specifically, dry waterless wipe decontamination removes more toxin from canine fur than soap-and-water washing and reduces transfer to the skin, handler, and veterinary staff; soap-and-water washing in that context can facilitate transfer of the agent to the skin. Frontiers in Ve…
Supportive care follows decontamination and is tailored to the patient's hemodynamic and neurologic status. Intravenous fluid therapy is indicated for dogs with clinical signs of toxicosis, targeting blood pressure, lactate, pulse quality, capillary refill time, and heart rate as hemodynamic endpoints. Journal of the… Antiemetics are appropriate to prevent secondary aspiration pneumonia. Journal of the… Monitoring of critically ill patients should include frequent blood pressure assessment, electrocardiography, and blood gas analysis to evaluate acid-base status, oxygenation, and ventilatory function. Journal of the…
