I use a dremel on all of my dogs and it is so much better than cutting the nails. I have a italian leather sofa that they play on with their nice rounded nails. They never scratch or have problems with their nails. They don't mind getting their nails done at all either.
I actually bought the dog grinder at Petco as it is a little more heavy duty than a regular small dremel. I only did that after going thru two cheap dremels. I have had this one for over a year and love it.
