Dog Breeding 101...No puppies

Well, Asia's due date has come and gone. To our sadness she didn't have any puppies. So, I guess we have a dog that we can't get trained due to bizarre events in getting her into class. And, a dog we can't get to breed. What now for poor Asia? We have decided we will try breeding again as soon as she is in heat. If it doesn't take this time we know there must be something wrong and just get her fixed. Then we will try training again.
