Alan Titchmarsh meets Mili the Greek Harehound and her owners. Greek Harehounds were bred for tracking and chasing hares, meaning Mili's attention is often diverted by the wildlife near her home in Dorset. Alan introduces Susanne Broughton, an expert in 'mantrailing' who teaches Mili to track down a person from an item of their clothing. In just four weeks, can Susanne get Mili to focus and track down a hidden person in remote wood? Another couple are concerned about their beautiful Samoyed Yuki since their beloved dog lost an eye to glaucoma. Alan sends in expert dog trainer Beth Kent who can see the potential in Yuki as a therapy dog. Beth needs to get Yuki's liveliness back, and her final challenge takes place in a special needs school.
