Graeme Hall's first case takes him to the Midlands, where a wayward Jack Russell is ruining a precious relationship between a little girl and her grandad. Every time 10-year-old Darcy pops round, Milo won't leave her alone. Graeme also revisits Carol and Peter whose pair of puppy sisters were at war. Previously, Graeme managed to get them on the path to friendship, but there's trouble afoot.
