You should have known you were going to get these types of responses. You are on a "pit bull" forum for Christ sake. These are people who love and care for the breed tremendously. By you posting a thread wanting to know what the puppies will look like and clearly being excited about it SCREAMS irresponsible owner. It's impossible for us to tell you what these puppies will look like. These people are only trying to help you by telling you to terminate the pregnancy.
Hopefully you will make the right decision.
My gut feeling tells me you won't though.
A dog is not "almost human" and I know of no greater insult to the canine race than to describe it as such.
