No. Only a male can impregnate a female. No female mammal of any species can get another female pregnant. For mammals that have a "heat" cycle, being in "heat" is required for pregnancy by a male. If such a mammal (a dog for instance) is not in heat or doesn't have a male partner, pregnancy is not possible.
Yes, a female no longer goes into heat if they are pregnant.
Cats are notorius for having false pregnacies.
Female cats should not go in heat when they're pregnant because it may harm the fetus.
after they go into heat.
No they can not and they will typically not let a male mount them if they are not in heat.
no they do not it dose not matter
No, a dog must be in heat to mate successfully. Otherwise she will not get pregnant.
it means if she is able to get pregnant
my female jack russel has not been on heat since november, why is this/
Yes but it has a better chance halfway through heat
Yes, as long as the chihuahua is "in heat" and they get "hung" (which you will know), the pug can get the chihuahua pregnant.
Once a female dog goes into heat they are able to get pregnant.
