I want to make sure my boyfriend's dog is crate trained before my new pup comes in April. Should I use the electric collar if she barks non-stop?

This April, I will be getting a Doberman puppy. I have a Papillion right now who is very well trained and crate trained. The dogs will be separated most of the time, with visitation only when I am present.

However, my boyfriend has a Rottweiler/lab, Scout, that comes to visit during his son's visitation. She is a nightmare. She is spoiled, aggressive, unruly, etc. I have taken her down a few notches with basic obedience training and leash work with a prong collar. Over the past few years, it has really changed her demeanor significantly. The only problem is she only respects me and listens to me. When I am not around, she's back to her ways.

With my pup on the way, I need to make drastic changes in the house. I have decided that it is imperative that Scout is crate trained by the time the pup arrives. My boyfriend has told me that she goes "crazy" when placed in a crate. Therefore, he took her out immediately and she won. It was never considered again. Sort of like clipping her nails! She bites at you and whines and rolls all over and gets away with it. That problem I solved over a two week period, and am now filing her nails two to three times a week with no fuss.

As far as the crate training, I would like some suggestions before I go about it because I would like to do it right the first time (not that there is a right). I was going start feeding her in it with the door open for a few weeks. And when she gets used to that, close it, and then let her out after she's done eating. I would like it to be a positive experience. But if she has a fit, as usual, I just need some help as far as getting her in it and how long to leave her in it, etc. Should I use the electric collar if she barks non-stop?

Thank you for your time,
