Hi sorry the owner got back to me I misunderstood her there is no way she would let the pups leave at 4 weeks at the earliest 6 weeks if all ok but she has had the vet out to mum this morning and the pups are ok to feed off her just not that infected back teat ATM, she sounds like she really cares about her dogs I have taken on all your advice and I probably will not buy this puppy though, I didn't realise there was such a stigma with buying a not official breeder puppy, these puppies are here now and need good homes so it's really a catch 22 at this stage
