RSPCA officials are investigating after six puppies were dumped in a bin bag.

The tiny black dogs were found at the gate of private boarding kennels near King's Lynn on Monday morning, after a member of staff saw the rubbish bag moving.

It is thought they had been left there some time during the night. The puppies are aged between a week and 10-days-old and still have their eyes shut. There are three males and three females and all are thought to be Labrador-type dogs.

RSPCA rehoming co-ordinator Penny Skate, said: 'The puppies are being cared for by fosterers and are responding well to being hand-fed.

'We are extremely concerned for the welfare of their mother as she would still be producing milk to feed them and could develop an infection or complications.

'It is also worrying to think about how the mother dog is being cared for if the owner is capable of dumping six tiny puppies with little thought for their well-being.'

The RSPCA is asking anyone who has seen anything suspicious, or knows someone who until recently owned a black Labrador-type dog and puppies, to call 01485 541141 in confidence.
