Dogs that are frightened show it very obviously and, if you know what to look
for, you can prevent them from becoming even more worried and biting in self-defence.
Some dogs mask their fear in a display of confidence and bravado but, underneath,
they are as worried as dogs that run away.
Confusingly, some dogs will give an array of different signals as they pass
through a range of emotions. Watching for the different signals from tails, ears
and bodies can help to unravel these signals and give you a better idea of what
the dog is thinking.
