it depends on how close of a bond u have. will a bond make a dog scratch sometimes i beleive in certain dogs yes. what i beleive a bond can definitely do is make the dog fight harder and help in times of need i beleive a bond can can help in a situation of your dog being on the bottom and him seeing u there and you are talking him through it and get him to his feet a bond will also help relax certain dogs in those situations so they do not panic. believe me my dog no know and trust me and they definitely form trust in their owners and that trust can and does help them through situations
