nitesh, u r always writing that ur female is of poor health and size.. first u should take care of her health and proper growth and then only u can think about her mating. even most healthy and well developed bitches should not be mated before the age of 18 months. take ur dooggie to a good vet, ask him which health problems he can see in her, what shoiuld be done to improve her condition and growth. do what the vet advises and see her improvement. and when she is 18 months at least - and if her health is good by that time - than only u can look for a mate for her. if u allow her to mate now, not only her health will become worse during pregnancy, but the puppies may be born too weak and sick and not survive. and even if they survive u will not be able to sell them because people want to buy healthy dogs, not weaklings.
