About a year ago I learned that a bitch can actually be impregnated by more than one dog during a breeding, and can have puppies from multiple sires in one litter, all at the same time.
I was just curious to hear from the breeders about their opinion on this. Is this something that could be done responsibly to get multiple looks in your puppies with multiple sires? Have any of the breeders here done it before? Is it a controversial topic? In my mind, it would seem if you had 2 very nice stud dogs, you could potentially attempt to breed for two slightly different types at once. However, my understanding is that with multiple breedings (even with the same sire), because puppies are always born a specific day during the cycle, not necessarily a certain number of days after conception, it can be dangerous for the pups that were conceived later because they weren't in the womb developing for as long as the pups that were conceived earlier.
This is just a hypothetical question to prompt some discussion so I can learn a little more.
