If a driver has a chronic phobia to dogs, the licensing authority would expect this to be supported by a report from a psychiatrist or clinical psychologist before a driver is granted an exemption.
Os oes gan yrrwr ffobia cronig o ran cŵn, byddai'r Awdurdod Trwyddedu yn disgwyl i hyn gael ei ategu gan adroddiad gan seiciatrydd neu seicolegydd clinigol cyn y caiff gyrrwr ei eithrio.
