For a pet prescription, which option should be used as the date of birth?

• A. Pet's birth date
• B. Pet's species
• C. Pet's breed
• D. Last 4 digits of owner's phone number

Answer: (D)

The date of birth field for a pet prescription is meant to identify the patient and keep records linked to the same animal across visits. When the animal’s actual birth date isn’t known, using a stable, owner-related identifier works best. The last four digits of the owner’s phone number provide a compact, consistent value that staff can verify and reuse, helping to avoid mixing up pets with similar names. The pet’s real birth date isn’t always available, and the other options—species or breed—are not dates and don’t serve to identify the patient in the record.
