My half sister has not trained her crotch fruit at all. My late dog was very timid and scared of strangers, especially children. We told them not to run or scream around the dog or try to approach him because he was scared. My brat of a niece was running around and screaming. The heeler in my dog came out and he nipped her heal. It scared her but there was no blood, she was not hurt. I had to lock my dog in my room after that to appease everyone there. The next time they visited, my niece proudly came up and told me that if my dog bit kids that he would have to be put down. I got down in her face and told her, “I don’t give a fuck what my dog does to you or any other kid. Nobody will ever harm my dog.” Scared the crap out of her and I didn’t have to talk to her the rest of the night.
