Absolutely #1: Do not use the crate as punishment! (especially while training the dog to use it)
If the dog must be separated from the pack for time out, try using a small bathroom or laundry room. Later the crate can be used as time out, but not during initial training.
2. Put something that smells like you in the crate (blankie/stuffed animal).
3. Feed a yummy treat to get her in it.
4. Put a Kong toy stuffed with a little peanut butter, cream cheese, or squeeze cheese etc. in there to give her something to do.
5. Cover the crate so it is more like a den.
6. If it is her sleeping area, try and have it in your bedroom so she can feel like she is with her pack (and invest in earplugs for the first couple nights
)
7. If possible work up to longer stays during the day:
(a) Place her in the crate
(b) as soon as she stops whining let her out
(c) next time wait a minute after whining, time restarts after any whining of more than a second or so
(d) slowly work up to longer times
Remember to keep the crate small enough so she doesn't have enough extra area to eliminate in or you will negate your housebreaking efforts. She should be able to stand up and turn around but not pace. If you want to buy a larger crate for her expected adult size place a divider (metal or cardboard) in it to start with.
