There’s an old myth that dogs are allowed one free bite before their owners are liable for injuries. Of course, that’s false.
As sweet and as usually well-behaved as your dog may be, if it feels you or your family are being threatened, it may react aggressively. A bite from even a small dog can cause physical disfigurement and emotional trauma, especially in children.
Make sure your dog is properly fenced or tied while it is outside, always keep your dog on a leash while walking, and be sure there is no possibility that neighboring children can wander into the dog’s area.
If your dog exhibits aggressive behavior, try modifying that behavior by using the services of professional trainers. Most importantly give your dog proper care, treatment, and respect, which will help ensure a happy well-adjusted animal.
