Tasha and Kes are sisters who have lived together since birth. Their owners had a third dog who sadly died and when she did, something shocking happened - Tasha and Kes turned on one another.

Their aggression got so out of hand, Pat and Dave decided to divide the house in two, to keep the dogs apart. Worried the girls will get lonely, Pat and Dave have made another extraordinary decision. They too have decided to live apart, with Dave in one half with one dog and Pat in the next half with the other.

Whilst the dogs are never going to see eye to eye, the team believe that with the right approach, they could improve the lives of these two sparring sisters and bring their owners back together. Will they succeed?
