Megan and Dennis, two cute Border Terriers that are developing a taste for the flesh of local pet bunny rabbits; noble-looking Braccho Italiano called Chicho, who refuses to obey any of his owner's orders; and Alfie, a rescued Border Collie Cross who adores his lady owner but who attacks and intimidates any men who cross his path - even his owner's sons.

Jimmy Chew the Springer Spaniel, who's turned his owners' beautiful home into his own personal lavatory; Hamish, the mean and aggressive Standard Schnauzer, who's attacked ponies, ransacked a chicken coop and scared the living daylights out of a flock of sheep; and Joe Jnr the Bull Mastiff Cross, who's a street fighting hound who'll drag his owner along the floor in order to get to another dog and fight with them.

Some of the worst dogs in Britain come face to face with three trainers, who attempt to knock the dogs and their owners into shape with a strong dose of tough love and hard discipline. Tank is a cold-hearted, abusive English Bull Terrier with an eye for anyone but his owner. Loala is a snarling, barking Rhodesian Ridgeback cross who's always spoiling for a fight, and Benson isn't so much Great Dane as great big wuss.

Some of the worst dogs in Britain come face to face with three trainers, who attempt to knock the dogs and their owners into shape with a strong dose of tough love and hard discipline.

This week's Dog Borstal inmates are bad and big. There's a seriously nasty pint-sized Patterdale Terrier called Muttley for Robert Alleyne to tackle, and a blond Alsatian called Carla who's the biggest bitch on the block for trainer Lynne Davies. Can the team bring these hell-hounds back into line?

This week is Dog Borstal's toughest and most trying intake so far, as we meet out-of-control canines Casper, Tess and Wilson. There's trouble, tears and heartbreak on the road to reform and one owner has to face up to her worst fears...

Trainers Mic Martin, Robert Alleyne and Lynne Davies face another three misbehaving mutts this week. One Borstal inmate has almost killed his owner, another is close to driving his owners apart, and the third's ball fetish is keeping her owner off the street. Can our experts bring them to heel?
