[carmen in nj]

I was told never to leave them together all the time, also if he is not proven, you have to help him by holding her for him and maybe guiding him. also I tried the 12th day after first blood with my maiden bitch and my stud and she not only got pregnant with a litter of 5 but whelped exactly 63 days after first tie, I mated them the 12th, the 14 and 17th day of her cycle. She was still a bit receptive after that those dates but I kept a diaper on her so they will not do it without my supervision, 3 times is good enogh.. also I known of pregnacies without a tie, and no pregnacy even with a tie.
best of luck..
