normal for fur coming out in clumps/Is there a doctor in the house?

Is there a doctor in the house?
Hi It's Scooter's owner here. I'm new on this site & am trying to navigate the best I can here. Scooter is an 11 yr old female spayed DSH. She has some fur matting on her backside mosly. Am I too agressive in grooming here if I pull some fur out by hand. It doesn't hurt her. But Is it odd that some spots show faster than normal fur growth, so I pull some out.

I know I over did it once on the back of the head. There's a small bald spot there now. Growing back past 3 days, I notice. Could it be a sign of some internal infection, as well? She behave's normal. Any feedback is appreciated.
