Dogs Behaving (Very) Badly

Trainer Graeme Hall tries to solve more dog behavioural problems. He travels to Bristol where he meets the Cramptons, who were hoping a gentle, loving, placid giant St Bernard would improve their family life. But instead, they got Dave, who causes chaos wherever he goes. Graeme also meets Surbiton couple Gemma and Josh, whose pug Rodney has developed an extreme foot fetish.

Graeme Hall meets a Spanish Griffon called Arlo who hates his grandparents for reasons unknown, despite daughter Allison adopting him to please her ill father. Graeme also visits Sally to help with her lurcher's intense behavioural problems that have begun to scare off potential partners for Sally, before helping Dawn, who has been grooming her schnoodle Winnie herself due to her aggressive behaviour towards the clippers.

Graeme trains three different dogs with behavioural issues, including Colt the Doberman who's ruining his owner's chance of living with her partner due to his destructive habits of chewing up sofas, manhandling guests and causing chaos on his walks. Graeme also meets Scottie cross Hugo who hates fishing rods, going ballistic when he sees one, making it challenging for his owners to enjoy their supposedly peaceful hobby. Tackling Jarvis the Cocker, Graeme must figure out how to discourage his serial escape ways before this disappearing dog act becomes an even more serious issue.

Graeme Hall meets a Rottie who controls his family's every move, possessing a vice-like grip which makes moving around the house and going on walks a trainer tussle. Mother Gabby's baby Olivia has formed a chain reaction of sound with Jack Russell cross Kevin, causing him to react to any sound Olivia makes with a non-stop racket. A pack of six Dachshunds are disturbing the peace, kicking off whenever they spot another dog out and about, leaving their owners Sally and Greg as a loss with how to solve this issue.

He also visits the home of rescues Obie and Samson, who lose it on every outing.

Graeme meets boxer-dog Dre, who has a habit of destroying his owners home when they aren't there and causes trouble out and about, especially at owner Jody's mum's house. German Shepherd Storm keeps barking at everything and nothing when her owner leaves the house, and two Chihuahuas in Scotland have been waging war against one another, ever since their owners went away for a break without them

Graeme meets Pug Bertie, who loses it and starts screaming whenever he goes near a vehicle, and English Sheepdog Baxter, who has a tendency of weeing on guests and wrestling with them.

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.

In this rehomed and rescue dog special, Graeme Hall meets an ex-racing greyhound with a major hurdle to overcome - hard, shiny floors.

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.
