nothing really. Just be sad for a while. then she will improve, give it a few weeks.
Possible infections and even death.
if a male is separeted during mating it can die
If you try to separate a male and female dog while they are "tied", it will cause considerable pain to them both. During tying, the male's penis swells and locks into the female's vagina. This swelling needs to go down before they can be separated. Trying to separate them during this time could cause tearing of reproductive structures of both the male and the female.
It goes freaking crazy
No, but there is a lot involved and you should pick up a book to learn more. I'm assuming your new to the idea of breeding based on question.
It usually doesn't happen but its possible if the female is laying down.
You will end up getting a Rhino.
Can't happen. Biology simply doesn't match up.
I dont think so, take the dog to to a vet because that shouldn't happen.
No, If you are talking about a female dog which I assume your are, the dog's nipples should become more normal after it is able to go in heat and if that does not happen it, it will happen when the dog is pregnant It is the exact same way with humans.
a pitbull is a dog to keep separated from another dog unless it is his female dog. An adult pibull will get along with another one if raised together and trained properly but it is not a good idea to have a pitbull with another male dog loose.
because the dog is on heat It isn't fair to the male dog to think of his reaction to a female in heat as "misbehaving." He's just doing what his instincts tell him to do. If you don't want him trying to mount her, keep them separated until her heat is over.
