Yes, dogs can absolutely get heatstroke when exposed to high temperatures and direct sunlight for extended periods. Heatstroke occurs when a dog's body temperature rises above the normal range (around 101 to 102.5 degrees Fahrenheit) and can lead to serious health issues or even be fatal if not treated promptly. Certain breeds, especially those with thick fur, short noses (brachycephalic breeds like Bulldogs and Pugs), and older or overweight dogs are at a higher risk.

To prevent heatstroke, make sure to:
1. **Provide Shade and Water**: Always ensure your dog has access to shade and plenty of fresh water when outdoors.
2. **Limit Exercise**: Avoid strenuous exercise during the hottest parts of the day. Instead, opt for early morning or late evening walks.
3. **Watch for Signs**: Be aware of signs of heatstroke, such as excessive panting, drooling, weakness, confusion, or vomiting. If you notice these symptoms, move your dog to a cooler area and contact a veterinarian immediately.
4. **Cool Them Down**: If you suspect heatstroke, you can help cool your dog down by applying cool (not cold) water to their body, especially on the paws and belly, and using fans to increase airflow.

Remember, prevention is key! Always keep a close eye on your dog during hot weather to keep them safe and healthy.
