Most dogs do not object to nail trimming so much as to the sudden snap of clippers. This tool files the nail down instead, using a rotating emery head and a low-noise motor, which a lot of pets tolerate considerably better than the alternative.
It is small, roughly the size of a marker pen, which matters when you are holding it at an awkward angle with one hand and keeping a paw still with the other.

A realistic note: no tool will make a nervous dog enjoy having its paws held. Introduce it switched off, let them hear it running before it touches a nail, and do a little at a time. Grinding also takes longer than clipping. That is the trade you make for not catching the quick.
