Answer 2

Isn't this something you should know before you breed?

Irresponsible breeders are funny though.

***

I work in a pet shop and I'm the first to say we don't know everything. All I've learned about breeding I've learnt from educated people on here, since our shop is TOTALLY against breeding and therefore I'm not required to learn about it.

Stop being freaking irresponsible and playing god.

Answer 3

It sounds like you have no idea what you're doing. Did you do any research before trying to breed? Of course you should remove the male, he can get her pregnant again shortly after she gives birth, which is very unhealthy for her.

Why are you breeding? Think about it. Breeding is not a game... it's not a matter of just putting a male and female animal together. Mess with the wrong genes and breed the wrong animals and you could end up with some very sick babies. Do you know the mom and dad's genetic/health history at least three generations back? Pet store animals should never be bred, you know nothing about their health background. It doesn't matter if they seem healthy now or the vet gave them a clean bill of health... it's what's in their genes. There are more than enough small animals in shelters and rescues without more poorly bred ones being added to the overpopulation. There's a lot more to breeding responsibly than you might think. Please read and make a responsible decision:

you should stop breeding now and read this and everything you can find on the subject before breeding again.

Also you should ring the vet and see if what he has to say about it is a good idea to bring the dead pups to the vets

Answer 5

It sounds to me like the female is probably overstressed, and probably has been bred too much.

The males will typically be fine with the babies if they believe the babies are their own children, so from that perspective it isn't dangerous to leave the male in there if he's been in there for more than a week (they're bad at math, lol!) because he'd help raise the babies.

BUT...there is a different, very good reason to take the male out.

A female mouse can and typically will get pregnant again within one or two days of giving birth--she can get pregnant right away if the male is still in there.  

So now you have a female who is nursing one litter and incubating the next.  That requires a lot of calories and nutrients--particularly calcium to grow the skeletons of two litters--and is really bad for the health of the mother.  

A mother mouse who doesn't think her litter will survive will kill and eat them in order to invest in the next litter which might have a better chance.  If she dies, after all, the babies will, too, so there's no point from a survival standpoint for her to feed her litter to the point she'd die, because they die, too.  

So if you have a female mouse in there who is getting pregnant over and over and giving birth to back-to-back litters because she's housed with a male, I can easily see that she's too depleted to raise the babies once she has them, so they die.  

Responsible breeders who breed pets only allow the females to have at most 3 litters, and here's how that math works.  Female is full-grown at 3 months, put her with the male then.  Babies are born 3 weeks later, weaned at 4 weeks old when she's a month shy of 5 months old.  Then she gets a month off to rebuild her strength before the next litter.  Put her with the male again at a week shy of 6 months, they're born when she's 6.5 months old, weaned at 7.5, rest until 8.5 months, then IF she is still strong and healthy she can have another litter, but 9 months old is really the oldest you'd ever breed a female.

So based on this, my recommendation is to take the male out and find some sort of vitamin supplement for the female, because I think what's happening is repeated pregnancies have worn her out.  I probably wouldn't breed her again, her health may never fully recover if that's what's going on and if it isn't she's shown she isn't good at the baby thing.

When I have sick or run-down mice, I use Ferret-Vite which is a high-calorie vitamin-supplement goo, and I mix it with cooked brown rice so there's just a light coating of the stuff on the rice.  You need the rice because otherwise the stuff is so rich the mouse will get diarrhea and be sicker, and rice buffers most digestive problems.  Good luck!
