About 3 year back my saluki greyhound bitch had a litter of 13,,,we had the same problem with them not all been fed,,I managed to get hold of about 6 tins of that cow&gate baby formula for free off a mate and bottle fed them that as well as alternating them round on mother,,,they all survived.Good luck
