Ans: It is essential to file the nails after clipping. This will ensure that the edges are smooth and rounded. Sharp edges will result in bruises and scratches. Pets experience a certain degree of natural abrasion and filing when they walk on surfaces, especially hard rough earth. When such nails are clipped with a scissor or guillotine nail clipper, the edges are bound to turn sharp, and this may result in possible self-inflicted injuries when the dog scratches itself.
Pets are known to scratch themselves, despite high levels of hygiene, and it is best to ensure that the nail edges are smooth and round to prevent injuries. The use of a file or an automatic grinding device can help to smoothen the cut edge of nails.
