Simple treatment methods for dog poisoning:

1. If the dog ingests toxins within one to two hours, you can give the dog hydrogen peroxide to induce vomiting.

2. If vomiting is not successfully resolved, gastric lavage can be used after a long time.

3. Activated carbon can also be used. Activated carbon is a common adsorbent used to absorb toxic substances.

4. Use potassium permanganate or saline to enema the dog, allowing the enema solution to stay in the dog’s intestines for a period of time.

5. Sodium sulfate or magnesium sulfate is often used as a cathartic method for dogs to quickly eliminate toxic substances.
