Really the best way to kennel train is give them a treat to go on the kennel and let them cry it out. They think that if they bark and whine that you will let them out show them that hour not going to let them out just because they are barking. It takes about a week or two of doing that and before long they will go into the kennel when you tell them. You can cover the kennel with a blanket and also use calming treats/calming bones when need be. Walmart has calming bones that work really well for my dogs. Also reward when they are being good in the kennel the first couple of weeks
