If by "Session" you mean estrus/heat; no. A female dog can not get pregnant if they are not in estrus. Many female dogs can not safely carry a litter to term if they where bred during their first or second heat, and reputable breeders usually wait till the dog is around three years old.
No, but it is impossible to tell exactly when her first estrus will occur. Normally a pup will go into heat sometime in her sixth month, but is she is early, she may become pregnant without your knowledge.
most breeders wait for the second period but pitbull pregant in the first period has not shown problem.
as soon as a female has her first menstruation she can become pregnant
You can get pregnant before the first time you bleed because you ovulate before you bleed and that is when you can get pregnant.
it really depend on when the female get its period..but usually, as far as i know, it could be at age 12 After she begins ovulating for the first time. Usually between the ages of nine and twelve. She will ovulate for the first time without knowing it and approximately 28 days later will menstruate for the first time, so a girl can technically get pregnant before getting her first period.
if your question is "can a girl get pregnant before her first period", then, unless in a very unusual case, no, they cannot.
No. You can get pregnant in the week(s) before your first period.
No, it is not. But your young female may.
Yes, but only if its about a week before you first get it.
Yes. It is just like how after the first sex, a human can get pregnant.
Yes. All it takes is once.
Young female cattle are called heifers before they are bred and often--in the dairy industry--referred to asSpringers and Heiferettes the first time they are bred and before they have had theirfirst calf. After that they are cows whether they are pregnant or barren.In the beef industry, such animals are often known as bred heifers.
