Spread each toe out and push the nail outward. Then clip where it looks clear, move on to the next nail. After you try to do each nail, even if you miss a nail or all, then and only then do you consider the nail clipping routine done. Sooner or later you will get all nails and he will stop fighting. He honestly can't tell if you clip or not as long as you remain in the clear section of the nail.
Some breeders prefer to clip after a bath when the nail is softer.
I prefer to clip before the bath so not to get scratched during the bath. Front nails need to be clipped twice as often as back nails. Therefore once the routine is down, switch back nails to monthly and front nails to bi-monthly. A good way of keeping track of everything needed is to associate it to something. If you cut the nail too far and it bleeds, monitor it well and apply a little pressure to stop the bleeding.
