How to report a dangerous dog
Keep yourself safe.
If you come across an aggressive dog, particularly an unattended stray, the best thing to do is to slowly back away from it before you get too close. Aggressive dogs do not like you to enter their area, so don't be tempted to try to calm it down by moving towards it.
Available choices:
[1]. Plus, by approaching it and gently backing away, you are free to let your instincts take the lead. If you are not able to approach your dog, it will probably be too busy or distracted to notice that you are approaching it.;
[2]. Instead, try to approach it slowly and softly, eventually slowing down the distance. If you're within a safe space, like your own home or car, try to approach your dog in a calm, encouraging manner.;
[3]. If you run, the dog may go after you and attack. Keep calm, avoid strong eye contact, and do not enter their space.;
[4]. Don't approach a dog by yourself and ensure all your passengers are safely nearby. Don't approach a dog over the speed limit.;
