NO! That's the whole point of getting spayed. If your dog is supposedly spayed and gets pregnant, first i would go to the vet and check before i assume she is pregnant. Then, if she really is pregnant, I would call up the place where the dog got "spayed" and sue them but make sure you have a reciet or papers of some sort
Generally not; a spayed cat will no longer come into season completely. She may still behave as if she were in season out of habit, but that should last at most only one cycle, and will not have most of the characteristics of being in season.
not always
No she shouldn`t if she was just spayed she may have a false pregnancy
cats still have hormones even after spaying but heat should stop soon
