I use people toe-nail clippers on ZoE. I like that they are fairly small and easy to operate. I buy them at Rite-aid, use them til they start to dull & then throw them out & buy new. They're really cheap. I just trim off a lil tiny bit every week after her bath, as its's easier then to move her feet hair out of the way & just get the nail. She's 10 months old & is totally used to me doing it now.
I just cut her nails tonight and then took her for a walk on a local paved walking path...that helps to file them a lil too
