I never bred any of my dogs past 5 male or female....although I have actually talked to one of the best pomeranian breeders who said that they had no problems breeding males until they were 8+ years but also said that females were retired at around 5-6 years.
Section 5. No dog or litter out of a dam under eight (8) months or over twelve (12) years of age at time of mating, or by a sire under seven (7) months or over twelve (12) years of age at 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.
I likely would not breed a bitch to whelp a litter after she turns 7 years old.
I much prefer breeding YOUNG bitches, but sometimes circumstances get in the way of that.
Male dogs, if they are healthy and willing, can be bred at ages quite a bit older.
Bitches, never past 6 yrs old, earlier depending on circumstance. Males studding is not as stressful as pregnany/whelping, so they tend to be able to breed longer, but also depends on the individual dogs health.
You know, that is an interesting question. I am going to say just from what I have experienced over the years, that no, it isnt the same in dogs. But if anyone knows of any research on this it would be interesting.
LPN actually as the male gets older there sperm isn't as good as it use to be. Especally around the 10 year mark.
Which is why at least a lot of the breeders I know that actually use an older dog. Has there sperm checked for potancicy and defects.
One ten year old westie the people I was working for at the time took some of his sperm to AI a female. Well we checked under the microscope like two to three minutes after the collection and almost all of them were already dead or they were missing tails and were dying. He did have a few strong ones, but I don't think enough that you would want to try and breed to him. They did though. In my opion the female was lucky she didn't take.
So it does happen in dogs too.
I figured as for breeding the female no older then 6 and the male no older then 8.
