Delivery people, beware! White German Shepherd Rio will go for anyone who knocks on the front door. His owner, Pav, has had enough, but can a week at Dog Borstal cure Rio of his irrational behaviour? Amber, a handsome looking Rhodesian Ridgeback, has a bark that's worse than her, well, everything! Things have got so bad her owners are threatened with eviction. Amber is in the last chance saloon. Saving the best (or should that be worst?) until last, feisty Yorkshire Terriers Duplo and Abbie are the scourge of their cul-de-sac. They are jointly charged with aggressive behaviour on the streets. This terrible twosome could provide the biggest challenge yet for the Dog Borstal team...
