I love the name Moose for a little dog. I know he will have attitude! I see you are looking for suggestions on how to get your dog to use a puppy pad inside. Most puppy pads have a scent to attract the dog, so this should be all you need.
My only concern is placing the puppy pad in a crate. Is Moose sleeping in the crate as well? Most dogs will become stressed if they are forced to sleep and go potty in the same location. If you want to train Moose to go potty in one area, may I suggest having a crate (with his bed inside and chew toys) and have the crate door open to a play area. Make one with the baby fences you can buy at walmart. This will create a 6-8 foot play area, and in that area you can place your potty on one side, and water on the other. Moose will have an area to sleep, play and go potty. Once he is used to the area, you will no longer need the fence. It is important to keep him confined during training.
