Is it possible...

are you trying to ask can the dog still go into heat while she's pregnant?
i dont really understand your question either

Maybe your trying to ask if a dog can go back into heat and get pregnant after she's recently had puppies, if so.... Yes, bit*hes usually go into heat every 6 months, some sooner, some later.

I understood it as "can they go into heat after being spayed". If that's what you're asking, then no. If not, please explain your question better
