Mystery question about breeding

Question
Hi, I have read almost every book on dog breeding, and have learned everything, except what I want to know. I've asked several dog breeding experts, and have had several "different" expert answers. Now for the question... When you breed your bitch, Does she conceive 1-2 or 4-6 pups the first time she is bred? Does she conceive 1 pup each time shes bred? Does her eggs stay "available" throughout her breed cycle. Maybe she gets 1 pup the first breeding, then 3 the next breeding? I been told the bitch could have several fathers to her litter. If this is true, then you must have to breed her several times to get a larger$$$$ litter. Maybe all the above could be possible? Sorry for the long question. Thank you Torry

Answer
HI TORRY,
ON THE FIRST TIE OR BREEDING TO A STUD DOG IS WHAT YOU GET BE IT ONE PUP TO IN SHEPHERDS CAN GO TO 14 PUPPIES.  I BRED ROSETTA LAST YEAR ON HER 16TH HEAT DAY AND SHE HAD TEN PUPPIES.
I BRED HER THIS TIME ONE TIME NOV 16TH, NEXT DAY SHE WENT OUT OF HEAT.  I DO NOT ALWAYS EVEN BOTHER A SECOND TIE OR BREEDING.  I HAVE TRIED THE LATE DAYS OF HEAT FEELING MORE EGGS DROP TO THE 10 DAY OF HEAT AND GET WHATEVER IS MADE FROM THAT TIE.  I GET LONG TIES WITH GINO ONE OF MY STUDS, BUT FOR EXAMPLE SASHA LAST YEAR FIRST LITTER HAD SEVEN PUPS, THIS PAST SUMMER SHE WAS LARGER AND ONLY HAD FOUR.
ONE NEVER KNOWS, BUT I DO NOT BELIEVE IN MULITPLE BREEDINGS, THE FIRST TIE IS THE DATE WE GO BY WHEN THE PUPS ARE BORN, SO I FIGURE WHY WASTE THE STUD FOR A SECOND TIE IF WE HAD A GOOD FIRST BREEDING.  I DO BELIEVE IN WAITING TILL LATE INTO THE HEAT TO BREED AS I PERSONALLY FEEL MORE EGGS ARE THERE.  JUST MY OPINION.
