DOGS Behaving Very Badly couple were left open-mouthed after an expert totally transformed their pooch after one walk.
Tuesday night's instalment of the Channel 5 show saw trainer Graeme Hall help a handful of pet owners sort out their naughty pups.
Graeme headed to Lincolnshire to assist Kelvin and Helen with their misbehaved Patterdale Terrier called Ted.
They told the expert that since rescuing the pooch two years ago, he has been causing them issues that have made them concerned he may have to be put down.
They explained that the pup hates visitors in their home and shared their concerns that he may end up seriously hurting someone.
Ted also makes it difficult for the pair to cook in the kitchen because of his dislike of tinfoil, the oven and the sink.
It didn't get off to the best of starts because when Graeme turned up at the house, as Ted made it very clear he wasn't happy with his presence.
The expert came up with an action plan to help the pair, and wanted to start by building a bond with Ted.

Kelvin, Helen and the expert took him out for a walk away from their home so they were on neutral ground.
They were left amazed when the pup allowed Graeme to hold his lead and he walked next to someone that wasn't his owner.
As they watched on, Kelvin said: "It's absolutely amazing that he no longer wants to eat Graeme, he's no longer aggressive towards him and he's pretty much doing what Graeme is telling him to do."
Graeme hoped that with their growing bond, Ted would go onto accept him on his own turf.
And as if by magic, the furry friend wasn't phased with him being in the living room with him - and even sat on the sofa with him.
The trainer returned to Lincolnshire at the end of the episode to help them with his odd kitchen behaviour.
He told the couple to tell Ted what they don't want and reward him with good behaviour.
When they went to open the oven, they told the pooch to sit and gave him a treat.
At the end of Tuesday night's show, Kelvin was able to open and close the cooking appliance without Ted going for the door.
Kelvin said: "Graeme has proved to us that we can train these traits out of Ted, and that he can learn to behave, accept strangers, and accept cooking in the kitchen!
