GETTING A LITTLE WORRIED NOW!

Question
I HAVE A 2  1/2  YEAR OLD SHORKIE FEMALE SHE IS IN HER (ALMOST) 2 WEEK OF HEAT.
MY MALE IS A YORKIE. HE IS PROBLEY ABOUT 4 TO 5 POUNDS SMALLER THAN HER BUT THEY ARE TOTALLY COMPATABLE. SHE HAD  A LITTER FROM HIM 1 1/2 YEAR AGO IT WAS A PERFECT BIRTH AND NOTHING WENT WRONG. SHE GAVE BIRTH TO 6 PUPPIES TOTAL THEY WERE ALL HAPPY AND HEALTHY BABIES. WELL AT THAT TIME THEY ONLY LOCKED (TIED) 3 TIMES TOTAL. WELL FOR THE LAST 4 DAYS THEY HAVE LOCKED 13 TIMES AND HE AND HER STILL WANT TO BE TOGTHER. I TRY TO SEPERATE THEM BUT THEY BOTH CRY ON EACH SIDE OF THE DOOR AND WHEN I GIVE UP AND LET THEM TOEGTHER IT IS CONSTANTLY WERE THEY BOTH WONT LEAVE EACH OTHER ALONE. SHE EVEN TRYS TO MOUNT HIM AND IT GOES BACK AND FORTH! SO I ACTUALLY HAVE TO QUESTIONS BEFORE I FREAK OUT..IS IT TRUE THAT "THE MORE THE DOGS LOCK...THEY HAVE  MORE PUPPIES"?? I MEAN THEY HAVE LOCKED 13 TIMES AND I WOULD HATE TO PUT HER IN DANGER..BUT I WAS TOLD THAT THE MORE THE DOGS LOCK THE BIGGER HER LITTER? TRUE OR NOT TRUE?
AND THE NEXT QUESTION IS SHOULD I NOT LET THEM LOCK ANYMORE CAN THIS DUE HER HARM? I MEAN AT THIS POINT I JUST WANT HER SAFE.
THANK YOU,

Hi Jennifer

If she's at day 14 she may still be ready to be bred and the first few times were "practice".  

If he has successful tied 13 times, chances are the semen that he does have left is poor quality if, that is, there is any viable semen left.

The damage that can occur is a chance of infection in the female which can in turn adversely affect the female and unborn pups.  A breeding male and female only need to tie once a day over a course of 3 - 5 days, anything else is overkill.  

I would keep them separated and put up with the crying, she should be done soon.
