What is the best nail clipper for a larger dog's nails?

Either guillotine-style or scissor-type clippers work well to clip the nails on a large dog. The most important thing is to choose the tool most comfortable for use.

Guillotine clippers have a small stationary opening to insert the pet's nail into before squeezing the handle to bring a blade over the opening to cut through the nail. Scissor-style clippers are positioned around the nail, and the handles are squeezed together to cut the nail similar to a pair of scissors. The ASPCA recommends visiting a pet supply store to try both styles and determine which one works best for each individual pet and owner.
