According to me it will depend on the parents height, plus there are no fixed rules to it. Feed your dog a good healthy diet along with supplements advised by a good vet and you will have a healthy and good dog. Size etc will depend on the parents and it is not neccessary that all pups will be like the parents.
What you should keep in mind is that you have a wonderful dog and that you should train it properly using praise and tit bit and never use force or hit a dog. treat him well and train basic obedience atleast and you will have a loyal friend for live who will protect you when required.
All The Best. Just Enjoy Your Dog and dont go by what others have to say etc.. They are wonderful to have and love.
