In episode three, Paul meets four-month-old stray puppy Patrick, found wondering alone on a London street on St Patrick's Day. Just two days after arriving at Battersea, Patrick is rushed into the clinic with a horrific injury needing urgent surgery - a wooden kebab skewer sticking out of his tummy. Paul also meets Tyler, a Yorkshire Terrier who is brought into Battersea by his owner, a nurse working long shifts who has struggled to give him the love and attention he needs and a 12-week-old Shih Tzu puppy called Mimi, who arrives at Battersea because her family's other dog didn't get along with her.
