I was trading out a chew bone with an actual toy with my 13 week old puppy and she latched onto my nose and bit down really hard and it started gushing blood. Is this resource guarding? And how do I prevent it?

I got her this bone to prevent her from biting me as much and it’s bacon flavored, but I decided that I didn’t want her to have it all the time just because I’m supposed to supervise her while chewing on it since it’s rawhide and when I went to replace the toy with a different one, she latched onto my nose and it started gushing blood and I said very strictly no, and she got off, but I wanna know what I can do to prevent this
