There is none, if she's pregnant you will start seeing signs such as her nipples getting longer and the hair pulling away from them, her stomach getting bigger in about 2-3 weeks
See if the dog is lactating, or is she restless?
As long as it is not a female dog it is. Male dogs are called "Dogs". Female dogs are called "Bitches". See the related questions "What is a dog when it's not a dog?" and "Is my dog a dog?" for more information on these interesting questions.
You take your dog to see your Veterinarian immediately. There are cancerous tumors called perianal tumors that are dangerous. Get her in to be checked up by your Veterinarian before these tumors get any larger. Is your female dog spayed? You usually see these types of tumors more in an unspayed female dog. This is one of many reasons to have your dog spayed.
Yes, she can. All female animals with a vagina can get an irritation in their vulva (vaginitis). See a vet if you are worried your dog may have this.
You can tell if the dog needs to go to the vet if it might be showing signs that its is weak or the dog might not be its usual self.
I have a male that does it to everything. Not something we particularly like to see, but it is normal.
It depends. If the pup is male, it is just a dog. If it is female, it is called a bitch. [Please Note - "Bitch" is the accepted term for a female dog. It is not only an insult towards other people. See related links below].
Maybe 24 hours.

If you see a female who is very "loose" then she would most likely be willing to rock your world.
A male dog has NIPPLES (not breasts) because as a zygote (when he was in his mother's womb) there was a time when only the X sex-gene was activated, thus causing him to have nipples. It is the exact same reason human males have nipples. If your male dog has breasts, like a lactating female dog, then please see a veterinarian. Or check to see that your dog is really a female.
Simply look between their rear legs and see if they have a penis or not.
