My last 2 litters of Biewers were conceived like this. Chrystel was mated with da Cruiseman on a Tues and Wed..12 & 13 days. I rested him a day and bred him ONCE to Ilsa on Friday. I had the same number of puppies in each case. 
I do NOT like to get only one tie but that was all my male was gonna do. Guess he knew what he was doing. I prefer 2-3 ties between 11-15 days. The OOPS! breeding between Chrystel and Remi was on the 17th day of her cycle and I am POSITIVE of that. I swear, they just love to make us scientific minded people nuts. They are gonna do what they wanna do, no matter what our plans. 
Anyhow, I would try for at least 2 ties from either of your choice...     |
