Your message cut out how old your puppy is, 8wks or 8mos?
Have you tried putting a kong in there? Our puppy doesn't much like hers either, and there is a small amount of crying and going - on when she's in it (or the puppy play pen). I use the pen more than the crate and I've found that if I continue on with my day, or sit at the table where she can see me but also not encourage her.. She's become more used to it.
I use the crate in the car and at first just kept pushing kibble through the front while she was upset. Now she generally will go to sleep in it once we get going. However every so often she starts up.. And there is really not much we can do about it. She whines and cries for a while, but then settles down.
Are you letting her out when she cries? I only let Ollie out of the pen when she is quiet and seated. Make sure you wait until she's quiet before letting her out, no matter what ruckus she's making. You know she's ok, she's not hurt, she can see you.. So it's not like you're hurting her or neglecting her. I also try to make sure she's all played out before putting her in. If she's got too much energy then it doesn't turn out well.
We also have a crate in our bedroom that is used occasionally. If she cries then I let her know I'm still there, but that she's fine and needs to settle down. "You're fine, go lie down" then I basically ignore her, while she can still see that I'm there (lying down, watching TV whatever). She's been good with adjusting. We are "bad" though and let her sleep in our bed at night. I'm working towards her sleeping in the crate eventually. But bed-dogs aren't a big issue to us.
I'm not in a rush and don't mind that it will take us longer. I only just recently crate trained my 7yr old little dog.
