I have a Doberman mix but I would like to know if ?

I got a female doberman mix from a shelter and now she is almost 11 months old. As for her size she is 23 .5 inches tall at the withers and weighs 60 pounds, I know she is not getting any bigger or heavier at this point but I would like to ask the following : I did not get to see any of the parents since I got her from shelter but the vet told me that she is a dobie mix. If the dog is seen you can see her she looks exactly like a doberman only smaller (as I stated before she is 23.5 inches at the withers and weighs 60 pounds in comparison to a purebred female dobie which I have heard that are like 25 inches tall at the withers and 75 pounds in weigh), so my question would be that if she had puppies with a purebred male dobie,what are the chances that the offsprings could be more doberman like in structure and appearance. Is it posible that the offsprings of her offsprings will get closer to what a doberman looks like if they get crossed with purebred dobermans?

P.D I am not trying to go into selling puppies or anything because for starters I do no know anything about breeding dogs.
