They can be that way sometimes. But before you want to pet a dog ask his/her owner first. Some dogs are scared of humans so they have to defend themselves. If you get bit by a dog don't blame the dog. It wouldn't bit you for no reason. so if you get hurt by one think about what you have done to to the dog before you blame him/her. Trust me have more dog smarts than anyone else on this planet. :)
