Here's what you should do:
1. Call your veterinarian immediately. They will be able to assess the situation and advise you on the best course of action.
2. Take note of the type of ant poison your dog ingested. If possible, bring the container with you to the veterinarian.
3. Note the time of ingestion. This will help the veterinarian determine the appropriate treatment.
4. Keep your dog calm and quiet. This will help prevent further complications.
5. Follow your veterinarian's instructions carefully. This may include taking your dog to an emergency animal hospital.
Important:
* Do not wait to see if your dog shows symptoms. Some ant poisons can cause serious health problems even if they don't immediately show symptoms.
* Do not attempt to induce vomiting unless specifically instructed by your veterinarian. This can sometimes make the situation worse.
* Keep ant poison out of reach of your dog. Store it in a secure location.
I hope your dog is okay. Please contact your veterinarian as soon as possible for the best possible outcome.
