Re: How do you register a multi-sired litter with the AKC?
You can find all of the information on the AKC website. You need to do DNA on the dam, possible sires and all of the puppies. Once you have the results you can determine if there are really two sires or only one. Often even when two sires are used, only one is successful. If you really have two sires, you will have to pay an additional fee to register the litter. If you haven't already done the DNA, get started now. It takes at least 4-6 weeks to get results and you need all of them to determine parentage.
Re: How do you register a multi-sired litter with the AKC?
This information MIGHT be outdated after 4 years but probably not. Don't do multiple sires if the potential parents are too closely related. If the sires on the possibly multisired litter are closely related, with close relatives on both sides of the pedigree, as in some lines, it might be best to DNA first through DDC, then if it is truly multisired, use the AKC. If it is only single sired, then register as such, quietly. The AKC test is cheap and seemingly uses fewer genetic markers on their test, which sometimes leads to "re-do's" as they send it to another level of testing. I know a couple litters that could not be given full registration, but conditional registration, due to AKC's lower level of genetic testing. The breeder lost some great potential show dogs and, due to her choice, breeding dogs, as she didn't want conditional registrations in the pedigrees. The possible sires were closely related, in one case brothers, and in the other from the same close lines but father and son or something like that, with maternal relatives in the line. The DDC had it all figured out. Breeder would, in a do over, just have registered her keeper "litter," as she didn't get what she wanted with the other sire anyhow.
If it is an accident, proceed cautiously, perhaps testing with DDC first if the sires are closely related. Pet pups can be released with no papers, if it is in the contract and if local laws allow. Also consider skipping the multisired in close linebreedings if you are breeding enough to have a possible AKC inspection and their DNA testing, I presume.
