This video shows how to clip your Chihuahua's nails. Since the dog doesn't weigh that much you may need to clip the nails more often then a heavier dog. If you can hear the dog's nails clicking on the floor, then it is time for a clipping. Use cat nail clippers because they are smaller. If your dog has white nails, then just clip of the edge that is clear. If you look farther into the nail you will see there is a pink part. The pink part is a nerve. If the dog has black nails then just be careful and only remove the very tip. Don't forget to clip the dewclaw on the side of the foot.
