All dogs nails contain a blood vessel known as the ‘quick’. Cutting through this blood vessel causes extensive bleeding and considerable pain, especially in black nails. The quick is not always visible, and I will only cut the nail to a length I feel is safe. Each time a nail is cut, the quick recedes slightly enabling the nail to be trimmed again within a couple of weeks. Regular nail trimming is recommended in order to keep them to a short length. Many dogs will naturally wear their own nails through regular walking (especially on concrete). In these cases, the nails will not need to be trimmed.
