If the dog is with its owner, then I ask for permision to pet it. I have petted dogs that I don't know before like when I find a stray that I am going to rescue. I can usually read their body language pretty well and know when to stay away!

Drake can sometimes be unpredicatable and thereofre always insist that people check with me furst before they pet him. If Drake is not approached in the right way, he will growl and can snap He has never bitten anyone before, but I do not leave him unattended!
