Tired of catching these hands

So in all seriousness, I have a new rescue. Boxer mix, under a year old her name is Daisy. However I’m hitting a wall in training. No matter what I do she’s always pawing at me. My forearms and hands are scraped and scratched so much the dentist asked me if I’d gotten a cat for Christmas this morning. She comes from a situation of neglect and physical abuse and she’s fallen in love with loving touch and wants it all the time now and she always pulls at my hands to pet her.
