Naval veteran Mark moved to Cornwall for a fresh start and to be closer to his daughter, with his three Frenchies: Mooki, Milo and Yogi. Surrounded by some of the most beautiful coastline in the country he had dreams of long meandering walks, while breathing in that crisp sea air. But all this ex-sailor is getting to soak up is the sheer mutiny his troublesome trio are causing on every excursion. Passers-by are terrorised by these four-legged marauding pirates and Mark's reached breaking point.

Ella and Owen got Stanley as a therapy dog for their daughter, who has autism, and a companion for the whole family to enjoy. But rather than bringing an air of calm to the household, this Golden Retriever brings chaos, and his pandemonium is fuelled by his overactive libido. This shaggy-haired boy is a real leg man - cross his path and he'll latch on, bend over to do your shoelaces – well, you're in trouble. The family have had their fill of his shenanigans – can Graeme Hall teach him to love in a more wholesome way?

After being diagnosed with a number of health conditions, Stephanie had to give up her job and move back in with her parents. She'd always wanted a dog and to give herself a positive focus during a very difficult time in her life decided to take the plunge – so along came Chihuahua Bailey.

He sees off every house guest to the point that friends and family are refusing to visit and it's driving a wedge between Stephanie and her mum and dad.

Graeme Halle meets a frenchie who has lost the use of his back legs, but gained a tendency for barking at passers-by when he's in his buggy. The trainer also revisits Labrador Prince, who overcame his fetish for hair scrunchies but now seems to be bolting for something different, and sprocker Brodie, who has developed a new problem for Graeme to solve.
