What does your dog tolerate best? We've spent plenty of dough buying "The Best" Guillotines, Side Cutters, Human Toe-Nail Clippers. I have, at minimum, a dozen different pairs. Lots of research on the web. Talking to breeders, groomers, and paying to have it done. Our headaches ended. I found a Dremel Tool works best. Minimal nervousness for the animal, and the owner. No muss, no fuss, and quick.
