Is Your Dog Friendly?

Maybe I should go over the definition of friendly lady with the German Shepherd.  Friendly is smells my hand and then lets me pet him/her and maybe likes some back scratching.   Cujo Friendly is what your dog is.  He almost took my damn hand off and it was not like I sprinted up to it in a threatening manner.  That dog should work at Gitmo for God's sake.   You should answer the question I posed with a simple no.  "He is usually friendly" is like saying alligators are usually friendly when they are not hungry.
