I have been bitten.
It hurts, and can be a start of infection
Dogs that bite are a real danger to people and they can cause serious damage.
The larger the dog the more sever the damage, although a small dog can can cause damage to a face or even take an eye out
NO DOG BITES WITHOUT WARNING
When someone says the dog just bit with no warning, it means that they have missed the signals. The most obvious signs of dog aggression include raised hackles, stiffness, growling, snarling, snapping, or lunging, but there are more subtle signs that the dog is starting to become uncomfortable, which people often miss. These signs include whining, licking the lips, drooling, panting, showing whites of eyes, and ears laid back.
Education is the key…Dogs do not become aggressive on their own…Only people make dogs aggressive.
The ban on breed specific dogs such as pit bulls does not reduce dog bites. In countries with breed specific bans dog bites have actually increased.
