Our Extra Strong Nail Clippers is made from rust free high-grade steel, which after milling is tempered and ground. The specially formed cutting edge is designed in such a way, that all-round the nail from the outside to the inside is cut, with it chipping of the nail is effectively prevented. The plastic handles are ergonomically constructed. As extra strong product, this nail clip is designed for big dogs. Of course, this can also be applied for all dogs with tough nails. If you are unsure, you should leave the nail cutting to your vet, this applies especially for dark nails by which the inner lying blood vessel is not visible. If you wish to do the work yourself regardless, please grope your way on slowly and always cut off only a small part of the tip.
