im looking at getting a german shepherd , have been looking for a while now. My better half knows a friend who has just had a litter of ten pups, only two of which have survived. She thought it was because they had a long birth ,but i suggested it may be an e coli infection from the mother so she took them to see the vet and it was confirmed. My question is, if these two pups do survive, what ,if any long term health issues could there be ?
