1. **Excessive Panting**: While dogs do pant to cool themselves, excessive panting that seems labored can be a warning sign.
2. **Drooling**: Increased salivation or drooling can indicate that a dog is overheated.
3. **Weakness or Lethargy**: If your dog seems unusually tired, weak, or is struggling to stand, it could be a sign of heatstroke.
4. **Rapid Heart Rate**: A noticeably fast heartbeat can be a sign that your dog is in distress.
5. **Vomiting or Diarrhea**: Gastrointestinal upset can occur in dogs suffering from heatstroke.
6. **Bright Red or Darker Gums**: Healthy gums should be a light pink color. If they appear bright red or darker, it could indicate overheating.
7. **Unresponsiveness**: In severe cases, a dog may become unresponsive or faint.
8. **Seizures**: This is a critical sign and requires immediate veterinary attention.
If you notice any of these signs, it's important to act quickly. Move your dog to a cooler area, provide water, and use cool (not cold) water to help lower their body temperature. If symptoms persist or worsen, contact your veterinarian immediately. Prevention is key, so always ensure your dog has access to shade and water, especially during hot weather, and avoid strenuous exercise during peak heat hours.
