As far as I know, AKC doesn't require any proof. They will register any puppy from any two AKC parents that you provide. I have never had this problem so you might want to contact AKC and ask what happens when one litter has two fathers. I guess you would need to register two litters and then AKC might want the DNA results, but it will be your responsibility to know which puppy belongs to which DNA test results.
I have never used this lab for dogs, but have used it for sexing birds. |
