Dogs Behaving (Very) Badly

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. Stephanie loves Bailey very much – the trouble is her parents don't. 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.

This time, Graeme takes on some of Britain's most pampered pooches.

First on his list is Chihuahua Chilli. His lavish lifestyle has become the stuff of legend, with tens of thousands of followers on social media. And when he's not getting likes – he's getting snapped at all manner of events or collaborations. So, it's no surprise that this doggie-influencer attracts attention from his fans… The trouble is this social media star is seriously anti-social and, true to his name, little Chilli has quite the kick. If anyone approaches, he gives them the heat and owner Yasmine is worried his short-fused ways could get him #Cancelled.

Next, Graeme heads back down memory lane to revisit a seriously pampered pooch he first met a few years back - Great Dane Trip. This princely hound was waited on hand and foot by owner Elle. Not only did she make his eggs with coconut oil, but he also had regular vegan bubble baths and his very own bespoke bedroom with wallpaper to match his harlequin print. While Trip was Prince Charming at home, once he was outside, he became a right royal pain – going bonkers at anyone that came near his princess. Graeme managed to give Elle back some control – by showing trip she could look after herself and was no damsel in distress. But now Trip has moved to a new castle – Elle has a bigger problem to contend with.

Finally, Graeme heads back to Birmingham to visit Newfoundland Monty. Three years or so ago, the only way owners Adam and Heidi could get their 13-stone bear of a dog walking was to coax him with confectionery. Whether it was lemon drizzle cake or freshly baked cookies they would need to leave a trail of crumbs for him to follow. But Graeme had a deliciously simple plan to get Monty moving - replace the taste of cake with the sweet sound of excitement. Now he's heading back to tackle a new rather stubborn problem.

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.

In this rehomed and rescue dog special, Graeme Hall meets an ex-racing greyhound with a major hurdle to overcome - hard, shiny floors. The trainer revisits Romanian rescue Betty to see if her relationship with owner Nick has improved. Graeme also heads back to see rehomed newfoundlands Simon and Panda, in order to discover if his plan to quell this feisty pair has worked long-term.
