When do you feel puppies moving in a pregnant pitbull?

How far into pregnancy of a female dog(pit bull) does it take until you can feel the puppies move?? Also does the amount of teets mean thats how many puppies she will have??

When she starts to get fat you can feel the puppies moving around, be gentle. The amount of teets has nothing to do with the amount of puppies. The more teets the better though because if she has more puppies than teets that isn't good. I had a dog that had 10 puppies and 8 teets and a puppy died because it wasn't getting enough food. where do you live? My boyfriend has a male pit bull that needs a girlfriend. He only wants a pit, of course.
