The RSPCA are trying to track down those responsible for dumping four helpless puppies in Brighton in the pouring rain and freezing temperatures.
The dogs were abandoned just metres away from the RSPCA centre on Wednesday night.
Passers-by contacted the RSPCA after they found one collie puppy and another two lurcher pups, thin and shivering in a gateway on Braypool Lane at 9pm.
RSPCA Animal Collection Officer (ACO) Julie Parsons was called to the heartbreaking scene and rushed the poorly puppies to the vets.
Parvovirus is highly contagious and can often be a fatal virus for dogs. It mainly affects puppies between six weeks and six months of age - often after they are weaned too early or stressed.
