GizmoMom, Yes, the long hair could get caught in the Dremel and usually they recommend trimming the hair first. I looked at the sanding block and if you like the way it feels when you hold it I would give it a try. I currently use a nail file that is 100 grit but also a Dremel with a 120 grit. I have a large dog with BIG tough nails so the Dremel gets the job done much faster. He prefers either to a clipper. One thing to be aware of when sanding is that heat can build up from the friction so I do a little and then move to the next nail. I just rotate through them until they are the way I want them.
