Final answer:
A ring block for an onychectomy targets the digital nerves to provide local anesthesia during the declawing procedure.
Step-by-step explanation:
The primary target of a ring block for an onychectomy, or declawing procedure in animals, are the digital nerves that provide sensation to the toes. A ring block is a type of peripheral nerve block used in veterinary medicine to provide local anesthesia to the surgical area. It involves the injection of an anesthetic agent around the toe in a circumferential manner, which numbs the digital nerves, thus providing analgesia during the onychectomy procedure
