As man's best friend, many Australians keep dogs as pets to provide companionship, security and even assistance with several tasks (especially for disabled persons). As much as a dog may be trained, there is always a possibility that the animal may lash out and bite someone on the street. Indeed, random dog behaviour that is unexpected can occur at any moment. If your dog bites someone and causes personal injury, you may be liable for that person's treatment and other damages that they may suffer.
