2. **Diarrhea**: Along with vomiting, diarrhea can occur, sometimes with blood.
3. **Lethargy**: If your dog is unusually tired or lacks energy, it could indicate a serious issue.
4. **Seizures**: Some poisons can cause seizures, which are a medical emergency.
5. **Tremors or Shaking**: Uncontrollable shaking or muscle tremors can be a sign of toxicity.
6. **Increased Thirst or Urination**: Some toxins can affect the kidneys, leading to excessive thirst or urination.
7. **Loss of Appetite**: If your dog refuses to eat or drink, it could be a sign of distress.
8. **Difficulty Breathing**: If your dog is struggling to breathe, this is an emergency.
9. **Unusual Behavior**: This can include agitation, confusion, or aggression.
10. **Pale or Blue Gums**: Check your dog's gums; pale or bluish color can indicate a lack of oxygen or blood circulation.
If you notice any of these symptoms, it's important to contact your veterinarian or an emergency animal clinic immediately. Additionally, try to identify the substance your dog may have ingested, as this information can be critical for treatment.
