Who gets custody of the dog? This is the big question on the lips of desperate couples across Britain, who are sure they don’t want each other, but God help the one who misses out on the dog. Research shows that more than a third of dog owners in the UK would resort to the courts to get custody of a pet, and 30% of Brits would be willing to pay off their partner to secure ownership of their favourite pet. This dark comic and quirky special sees what happens to the shared pet when couples spilt up. When the love is over and the CD collection, photo albums and furniture have been divided – how do you then decide who gets to keep the pets? ONE Life (BBC One’s social documentary strand) follows a series of couples fighting over the pet, attempting to reach sharing agreements, talking via lawyers and wondering how buying a shared pet all those years ago could end up in this madness. This war over pets is now a very serious matter – one couple recently took their four pets into the courtroom for final judgement when, in the middle of the proceedings, the mouse died of heat exhaustion. While another couple have even gone to the US in order to try and clone their cat.
