Get it spayed. Spaying a dog means removing its eggs.
Estrus is the time in a female cats reproductive cycle which the female cat is receptive to the male cat. According to the question posted the cat had been spayed. If the cat has really been spayed it cannot come into estrus. If it has not actually been spayed and you just think it has, then it could come into estrus, but this is not dangerous (except she may get pregnant). Either way she will not die, or at least not of that!
The female should be spayed (fixed) at about 6 months. Some believe that she should have a litter before being spayed, but the only thing that does is add more unwanted dogs to the dog pound.
Female dogs are not less likely to have health problems if they have at least one litter of puppies before being spayed. That is a common myth, but it is untrue. Spaying actually helps to prevent some health issues.
Females are spayed Males are neutered
She will no longer have a period because when she gets spayed all the vet is doing is taking out her reproductive organs
No.
No
It's just like cat's, you're dog is twitching because it has'nt got used to being spayed because it's trying not to give birth to the baby's.So the female dog try's to force the baby's up and eat them.
