She is with me since she was born (I was there helping her mother give birth). So she usually doesn't try to bite when we play but I've a scar inside on my palm from when she had her baby teeth. Those were like needles. My scratches usually happen because she tries to wrestle me down and her nails scratches my arms in the process. As for your scars wear them proudly my friend. There is nothing to be ashamed of for paying the price while trying to have a good time ;-) Give your puppy some pets for me and a have a great day.
