I use a dremel type tool too. They both scream with the clippers, but aren't bad at all with the grinder. Don't get me wrong, they don't LIKE it, but they tolerate it.
I can't do all 4 of Jazz's paws at once. With Tango I do two at a time. It doesn't help that he has dew claws which also have nails and that's a pain because they curve really sharply as do a couple of his regular nails. So I grind them, and then have to use an emery board to file down the curvy part that's very close to the paw pad.
Annoying, and a bit time consuming, but not horrible.
