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.
Biochemical processes aren't like explosives. There (usually) isn't a definite on and off state. It takes time for the delicate chemical instabilities to be recognized and for reactions to take place. The actual condition of being pregnant is ill-defined: does it begin when the egg is fertilized, when the zygote affixes to the Uterial wall, or when the female at last reacts to the hormonal stimuli? There are instances know where a female has more than one offspring by more than one male in the same pregnancy. Proof that there is considerable biochemical lapse time.
A female dog does not go into heat while pregnant.
no
Yes.
Cats are notorius for having false pregnacies.
she is cleaning it, check to see if blood is present. If so then she is in heat and can get pregnant
A dog can get pregnant when it is in its 'heat'. A male dog can tell if a female is in season, but this can be any time in the year.
No, they are just as friendly and nice as they usually are =)
Maybe in the summer or around January. This is when female dogs go into "Heat". This means that they are ready to breed.
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.
No, when a mammal is pregnant it will not go into heat while it is pregnant.
Female cats should not go in heat when they're pregnant because it may harm the fetus.
after they go into 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.
Separate them, until the female's heat is over.
it means if she is able to get pregnant
