The EuroGroom Large Nail Trimmer is a plier style nail clipper that can handle any size nail, especially good for large breeds, heavy breeds and dogs with tough nails (if you have one of these boys you'll know what I'm talking about) especially cattle dogs and working breeds. If you have a small to medium breed or your four-leg has finer soft nails then please either use the quillotine nail trimmers or the small size nail trimmers.
