Lucy's insomnia

I had wondered the same with regard to noises from outside but we don't have near neighbours and the Milkman doesn't arrive until 7.00am.I suppose it could be a cat or a fox but the other dogs don't bark and Lucy didn't wake up when we were rocked by the earthquake last week.I have tried letting her out and then going back to bed but she wasn't having any of that.Perhaps she will get over it - fingers crossed, although with lighter mornings she will probably get worse. It's a good time of day for gardening in the Summer when it's hot - ha ha!!
