Don't worry everyone, I just did a quick search of the internet and there was nothing about dogs "eating their young". They talked about rabbits doing it sometimes because they don' have the instinct like dogs or cats who protect their young. I am sure Heather has talked to her vet or her mentor and she is just too busy with the whelping to get back to the computer.
Let's assume the best at this point otherwise I on't be able to sleep.
