Walking through the main reception and into the brightly lit and air-conditioned clinic at the back, I feel nervous and clueless about the evening stint ahead.
It's 3pm on a Friday and I've been invited to shadow veterinary nurse, Jade Yhnell, to learn exactly what happens behind-the-scenes at the animal equivalent of A&E.
Unlike most veterinary clinics that shut their doors at teatime, Vets Now in Newport stays open 24 hours a day, seven days a week, to provide out-of-hours aid to pets in desperate need.
