puppy help ☹️

I didn't know where else to post this but can someone help me out I'm not sure what this dark spot on my pitbull puppy's back is and her hair is shedding like crazy if I lightly tug on it a lot of hair comes out. I read it might be her puppy coat coming off but idk I'm still concerned can someone tell me what this could be 😐....
