My brothers dog was a cross Rottweiler, amazing dog. When he was a pup he would eat anything and everything, floor coverings... answering machines... you name it he would eat it. He was an incredibly friendly, calm placid dog that would cope with children climbing all over him because he was trained consistently, the only person he ever really growled at was an insurance guy who came to the door
He also never really barked, barking set him off on a coughing fit, crazy dog.
My dog is a horror, he was a rescue dog and hasn't quite grasped that he shouldn't go on the floor or steal food but we are slowly getting there. He manages to steal food though and that can be a major setback.
My dog barks at nothing and does it often, he's got such an annoying small dog bark too but we love him really
Dogs are great though
