No. Their hormones won't let them. Their bodies are geared for giving birth and lactating to suckle young. What good would it do from the standpoint of procreation for them to be in heat? "In heat" means they are giving off the chemical signatures associated with estrous, which is a change in the bitch that accompanies her ability to conceive. If she's already pregnant, she's not going to be conceiving, and her chemistry is different. It (her chemistry) will say, "Don't bother." Any males that may be interested know by her scent that they cannot impregnate her.
Cats are notorius for having false pregnacies.
No they can not and they will typically not let a male mount them if they are not in heat.
Female dogs typically go into heat, also known as estrus, twice a year. During this time, they are receptive to mating and can become pregnant. If a female dog has been spayed, she will no longer go into heat.
A female cat will typically stop being in heat once she successfully mates and becomes pregnant. If she does not mate, she will continue to cycle in and out of heat until she does. If she does not become pregnant, she may experience a rest period before going into heat again.
she is cleaning it, check to see if blood is present. If so then she is in heat and can get pregnant
Yes, a female no longer goes into heat if they are pregnant.
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.
Cats are notorius for having false pregnacies.
Female cats should not go in heat when they're pregnant because it may harm the fetus.
No, when a mammal is pregnant it will not go into heat while it is pregnant.
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.
It will stop bleeding after a while or it will not bleed at all
no they do not it dose not matter
Yes, any other time she can not get pregnant. I have never before heard of dogs getting pregnant while they were not in heat.
No, a dog must be in heat to mate successfully. Otherwise she will not get pregnant.
Male cats won't fight over a pregnant female. In fact, they couldn't care less about her if she was pregnant. But they will fight over a cat that is in heat.
