Hi! My girl, Holly, had her 9 pups on New Years Eve, (but one died for unknown causes) and I was wondering when they would be old enough to tell genders and how?
How are yours doing mojo? Have you posted any pictures yet?I was able to ALMOST accurately sex mine at three days using that guide. On the fourth day I swapped one over. Now at two weeks, it's extremely obvious, since the females have nipples. So since it's always good to double check, you can guess now and then wait till the fur comes in (but before it covers nipples) and check that way.
Mine are the result of an accidental litter because mom looked like a boy down there as a youngster, and was sold to me as a juvenile male. So some of her daughters possess this trait, as well, where their openings are farther apart than the diagrams and photos on that site show. Nonetheless, I kept looking at them every day, and by now it seems very obvious to me that even with the larger gap, my girls still have more closely placed openings than my boys. You can also look for the small bulge in males that will indicate their undropped testicles.
Still, nipples are the easiest way, at around two weeks. I can't believe my own girl slipped though the cracks--it is so easy to tell girls from boys that way. But I guess by the time she was weaned it was harder to tell, as the fur covers them.
Okay, great! I'll have to take a look at that! Their skin is beginning to change colors, and you can tell their markings. They all have markings only on their head (like their momma), so it is still a bit difficult to remember what they all look like. I could probably draw their head patterns and write their genders, so yeah.http://www.afrma.org/sexing101.htm
You can probably begin to tell genders apart now which will give you a boy and girl count if you're rehoming. However, you'll have to keep sexing them until the point where their markings are apparent and likely up until the moment you send them to new homes unless they all have unique markings. Before they grow a thick coat of fur, it's pretty easy to tell girls from boys because girls are the only ones with nipples (I wouldn't base your judgement off of this completely because they're hard to see sometimes). The link that I attached has pretty good photos of the different sexes based on their genital region. What I usually do is compare a few until I know for sure that I've got one girl and one boy and then compare the rest to them.
