Dog help

So our dog is around 10 years old, she's a medium sized puggle. But she chooses to lay outside in 85+ degree weather in the bright sun to the point where she's hot to the touch, I always give her a water bowl in the shade, and there's lots of shady placed in our yard as well, but she doesn't care. I'm really worried that she's going to kill herself doing this, and she refuses to come inside when I call her. Do you think she knows her limits and knows when shes actually too hot for comfort??
