So my little Sully has a pocket of dirt around her back leg. She's only 2-3 months old so I don't know how much I can pull on her back leg. Some of it comes out in her soaks but there is still a clump in there I can't get out. I tried brushing it out with a soft brush but she pulls her leg in so I can't get to it. (I'd take a pic but I'll have to wait till the hubby gets home to help) Any way for me to get this out on my own? Is this really bad for her?
