Opal's method of waking one up  

Opal is funny in the morning. Years of having countless pups has taught her one thing, how to wake up a mummy!

She must be the only dog in history to know where a human's bladder is placed, because for a good half hour before I woke up, she would pounce on my bladder... figuring that if she couldn't wake me, my body would! It worked!

I must be the only human in history to know what it's like to have a bunch of puppies pounce on a mummy's tummy!! Is this what Opal went through all those years through all her litters? Makes one wonder! She certainly learned where pups' tricks can be practical!!
