Basic dog body language will help you detect a fearful dog and take the threat away to calm him. Fear in dogs is the number one cause of aggression and they signal with different parts of their body to make the threat go away.
Dogs communicate with their body and every dog owner or pet professional should be able to read when a dog is afraid. Dogs can be afraid of many things: other dogs, people, sounds, strange objects, etc. They will display fearful body language signals to anything they consider a threat in the hopes that the threat goes away.
If you can see that a dog is fearful, you should move away from the dog and/or take your dog away from it. If you see that your dog is the fearful one, you should take him away from that situation. Never force your dog to interact with something that frightens him.
The key to understanding basic dog body language is to always read the entire body of the dog. Do not get fooled by thinking that because a dog is wagging his tail he will be friendly.
"An animal's eyes have the power to speak a great language."
In the canine world eye contact can be threatening. This doesn't' mean you can't make eye contact with your best friend, in fact you can teach him to make eye contact on command!
The important thing to know is that you should NEVER be threatening when looking into your dog's eyes. There are two types of eye contact: soft and hard.
Eye contact with soft eyes: Eyes are round and peaceful. This means the dog is calm and happy.
Eye contact with a hard stare: Direct eye contact with a hard stare (tense body posture) means arousal. This can be good or bad! Make sure you look for other body signals to figure out if your dog is in a playful mood or about to show aggression.
Whale eye: This happens when the dog is afraid to look at you, so he will actually turn his head the other way. At the same time he is not sure he should take his eyes off you, so with his head pointing away from you he will try to look at you! It is call a whale eye because you can see the white of their eyes. Dogs that have "whale eyes" are afraid and feel threatened.
Basic dog body language of fearful dogs includes mouth displays from showing teeth to growling and snarling. However, you will see that there are many ways in which dogs can show their teeth and each one has a slightly different meaning.

Always look at the WHOLE body of a dog to determine his state of
mind. As you have learned a wagging tail is not always friendly and
showing teeth is not always a threat. Understanding basic dog body language is a great way to bond with your pooch.
During playtime dogs make lots of body signals. If you think your dog (or someone else's dos is afraid) the best thing to do is to hold the dog that is chasing for a few seconds and watch the dog that is being chased. If the dog come around and wants to keep playing, everything is fine. However if the dog takes this chance to escape and hide, he was not having fun.
Always make breaks during dog play, it is very easy for them to get over excited or for a fearful dog to start attacking because he will he has no escape.
