Let me tell you a story...about 3 week`s ago my one of my dearest hound`s had puppy`s.It was a large litter so the pup`s were small,the mother`s milk began to dry up so we had to hand feed 3 and nurse Mom back with added diet and still allow 3 pup`s to nurse on her.It took a week to get her producing milk and to get her to feeling better.
Because we have been raising hound`s all our live`s we recognized what was happening and had time before the pup`s died.I still feel giulty because I didn`t react a day sooner but the point is if you don`t know what your doing thing`s happen real fast.Mother could die from giving birth and pup`s can needlessly suffer because of ignorance.
Some females don`t like some males and will not breed to them,most first time males don`t have a clue,male dog`s during heat can be too aggressive the first week and the female will not breed because she is not ready yet.Most animal`s figure out the sex thing on there own,some don`t.
