scaredy dog

My bulldog Gunny is scared of his kennel. Well, technically, he's scared of walking into it. He'll stay inside it fine. He'll exit out fine. For some reason, he's afraid of entering it. I think it's that little ledge in the opening of his kennel that he doesn't know how to outmaneuver. Anyway, I'm trying to get him to overcome it, but luring him in doesn't work. Well, I'll have to work on it for the next couple of days. My hope is that he'll be able to finally walk in by himself. Good luck to me...
