Panting
Panting is not a sign of danger. It is how dogs like to cool off if they overheat. Since they do not sweat like us, this is how they decrease their body temperature. When a dog pants, they are likely in need of water. It might also be their way of letting go of pain or stress.
Eye Movement
In some ways, dogs and humans are alike. We have the tendency to show our emotions in our eyes. Dogs also look at the ground if they feel sad or tired. On the other hand, their eyes are wide open and they look around if they are excited. If they raise an eyebrow, they might be confused. Make sure to pay attention to these things so you can better understand your furry friend!
