I would wonder about the advice that it is impossible to kennel train your dog.
I am not expert but our dog loves his kennel I built him one that is kennel as well as a peice of furniture these are readily avalible online. he spends a lot of time in it with the door open of course so that he is free to come and go this is where he goes to rest relax and or get away from the children the at night or when we need to go out without him the door get closed the whinning is most likely speration anxiety you could always try put a peice of clothing of yours in the kennel ( just not something you are attached to just incase ) and be patient pitbulls are extremely social animals and just want to be near the owners and once they realize that you are not abondoning them they will learn to love the kennel
