USPS steps on how to avoid being bitten
Don’t run past a dog. The dog’s natural instinct is to chase people who run.
If a dog threatens you, don’t scream. Avoid eye contact. Try to remain still until the dog leaves, and then back away slowly until the dog is out of sight.
Don’t approach a strange dog, especially one that’s tethered or confined.
While letter carriers are discouraged from petting animals, people who choose to pet dogs should always let a dog see and sniff them before petting the animal.
If a dog is about to attack, try to place something between yourself and the dog, such as a satchel, backpack or a bicycle.
