A spate of dog-nappings in London has sparked calls for greater pet insurance cover products.
Sainsbury's Bank has called on pet insurers to provide a minimum £250 reward for the return of lost or stolen dogs.
Sainsburys said only half of insurers offer the incentive.
It said it would like to see insurers offering up to £1,000 towards the advertising costs for a lost dog or cat and up to £750 if the pet is lost or stolen and not returned.
