How to protect yourself from a stray dog
Gauge the dog's demeanor.
Is it aggressive or afraid? Signs of aggression include: baring teeth, lifted tail, raised ears and hackles (the fur behind the neck, in many large breeds the hackles are very easy to see when they are lifted). Signs of fear include tucking the tail, laid back ears and also snarling or barking.

OUT: Barking is a sure sign that the dog doesn't want you any closer than you already are. Do not be mislead by breed stereotypes.
