If you suspect that your dog has ingested something toxic, it's crucial to act quickly to minimize the harm. Here's what you should do:

1. **Identify the Toxin:** Try to determine what your dog has ingested. Look for any remnants of the substance or packaging to help the vet identify the toxin.

2. **Contact Your Vet:** Call your veterinarian or an emergency pet poison hotline immediately. They can provide guidance on what steps to take next.

3. **Do Not Induce Vomiting:** Never try to make your dog vomit without consulting a professional. Some substances can cause more damage if brought back up.

4. **Follow Vet's Instructions:** Your vet may ask you to bring your dog in or recommend a course of action. Follow their advice carefully.

5. **Monitor Your Dog:** Keep a close eye on your dog's symptoms. Note any changes in behavior, vomiting, diarrhea, or difficulty breathing.

6. **Prevent Future Incidents:** After the incident, make sure to pet-proof your home to prevent similar accidents in the future.
