Yes. You can get pregnant no matter how old either one is.
No, a dog must be in heat to mate successfully. Otherwise she will not get pregnant.
Yes, a six year old dog is capable of getting pregnant.
Once the ovaries and uterus have been removed from a female dog, it is impossible for her to get pregnant. If a bitch 'believed' to have been spayed does get pregnant, it must then become obvious that the dog was never spayed.
If the 6 month one dog has tedticles and is sexually mature and neither if them are neutered, yes.
The male should be a few months old before mating and his testicles should have dropped
