Every dog is different. If you have mutual respect for one another and are bonded I could never see a dog you owned biting you.
I have been severely bitten by a GSD and a Labrador Retriever, and two minor bites from another GSD and a Doberman. That doesn't make me afraid of these dogs. One attacked without warning and the others I missed the warning signs. They were there though.
A painful lesson to be sure, but I understand a lot more now about GSD's than I did when I was much younger.
