Years ago before DNA testing I bred a litter of purebred airedales...the airedales tied at least for or five times during the first 3 or 4 days...toward the end of the heat cycle I bred her once with a mt cur dog...I did this because I knew I would be able to tell the difference if she had any half cur pups...and my logic also included that there wouldn’t be many crossed pups or any at all due to so late in breeding the cur to the Airedale...
Long story short...she had one pup out of 8 or 9 pups that was half cur...
My feeling is for multiple sires to have a chance at siring pups is to have both males to breed back to back with the female or fairly close...also my thought is that the first male might be the one that produces more pups...
I also think there are other factors involved but not limited to...such as sperm count and motility strengths and issues...
I’ve got a bulldog gyp that the last two litters she’s has had she’s had more than one sire, the first time it happened she was in heat and my dad called me and said he put her in a dog box in my backyard, when I got home i turned her loose and she went straight to a cur dog and tied with him and after hanging with him immediately tied up with a bulldog I had, I didn’t realize it happened until the pups were a couple of months old, she had two males that were clearly bulldogs, the head and jaw structure were identical to my male bulldog, the other 3 were females and it’s no mistaken they were off my male cur dog, they act and bay and are built identical to him...
Fast forward a couple years and this last litter I raised off her she had 13 and 4 or 5 of them were black and white, there’s no black dogs anywhere close in the last several generations of her pedigree or the male bulldog I bred her with, the ones that are black and white also have some ticking on their legs, a longer hair coat, ears set lower on their head and bigger than the others, and a few of them have noses that aren’t solid colored, the other six all have the color phase and patterns I expected to get, have nice round heads and short tight slick coats, and smaller ears that sit high on their head, my cousin lives in between me and my folks and has a black mutt yard dog that runs around and looks identical to the black and white colored pups and has ticked up legs and I noticed him hanging around my dog yard before I took her to my friends house and locked her on stock trailer and had her bred to his male...
I’ve read about it for years but have never contemplated actually doing it on purpose, the first time it happened it took me several months to completely convince myself that it had actually happened and this last time I’ve been just watching the pups as they get a little older, they’re about 5 weeks old now and I believe without a shadow of a doubt that the milk man from next door is the sire to the black and white ones, I know it’s common practice in the coon dog world and a guy I hunt with from time to time will tie his female to every male dog he has in his yard, and has been doing this for years, he isn’t trying to keep or breed up a line/strain of dogs, he’s just concerned about getting dogs to use and hunt and catches a pile of hogs every year...
