Ancol Guillotine Clippers
There are two types of clipper available, a guilotine action and a scissor action. With either type, be very careful not to cut the "quick" in the nail or claw. The quick is a blood vessel in the centre of the nail which if accidentally cut can be very painful for the dog and result in bleeding or possible infection.
If your pets claws are are very long then the quick inside the nail could also longer than normal. In this case it is recommended that the nail be but in small pieces every few days to encourage the quick to recede naturally. The correct length of nail is when there is a tiny gap between the floor and the nail when the dog is standing upright. This allows for extra grip when the dog runs.
