If a dog is poisoned and vomits, emetic drugs can be used. The effect is best within a short time after the poison is ingested. However, when the poison has been ingested for more than 4 hours and most of the poison has entered the duodenum, emetic drugs cannot be used.

If vomiting cannot be induced or vomiting is ineffective, gastric lavage is recommended. It is recommended that a doctor perform the operation under anesthesia in the hospital.

Under normal circumstances, it is recommended that owners put away such toxic and harmful substances to prevent dogs from being poisoned or killed if they accidentally eat them. Especially rat poison, cockroach poison, chocolate, etc. can cause rapid hemolysis of dog's red blood cells.
