I don't keep my dog in a kennel, He's too spoiled, so I don't know if this will work.
Start feeding her in there. When it is time to feed her, take her food bowl with food, and put the bowl inside the kennel. I would imagine that she will follow and sit in there and eat. maybe even stay in there with her for a little while and tell her good girl. Maybe if you ever give her a bone or a "special treat" give it to her in there.
I don't know if you do this or not, but don't use the kennel as someplace to put your dog when you don't want to give her attention. basically don't use it as a jail. If she does something wrong, don't punish her by putting her in the kennel, it will make her not like it.
just a couple of suggestions.
