I am assuming here that you are talking about clipping a dogs claws as apposed to his fur. I clip my dogs nails the same way I do my own, I even use the same clippers. The one important thing to remember her to to stay away from the quick. If you look close you will see a line on the dogs nail where the quick is located. If you clip the quick your dog can bleed to death. If your dog has black nails the quick can be hard to see so if you are not comfortable doing this then you should take your dog to a groomer or vet to have him/her clipped.
