Here is what AKC has to say about age and DNA...
How old must the sire or dam be in order for a litter to be eligible for registration?
Chapter 3, Section 5 of the Rules Applying to Registration and Discipline reads as follows:
"No dog or litter out of a dam under eight (8) months or over twelve (12) years of age at the time of mating, or by a sire under seven (7) months or over twelve (12) years of age at the time of mating, will be registered unless the application for registration shall be accompanied by an affidavit or evidence which shall prove the fact to the satisfaction of The American Kennel Club."
So, males are 7 months and females are 8 months.
Here's the DNA...
1. Which sires are required to be AKC DNA Profiled?
Effective for litters whelped on or after July 1, 2000, AKC DNA Profiling is required if a stud dog is classified as a Frequently Used Sire, meaning that he has produced seven or more litters in his lifetime or more than three litters in a calendar year.
So, males that have sired 7 or more litters in a lifetime or 4 or more in a calendar year.
Personally, I prefer the girls over the boys. I do not believe that girls are easier to potty train...at least not from what we've experienced. |
