I'm pretty much a wreck today. Only had 3 hours sleep and have a headache from crying. We go to the vet tomorrow afternoon. Mom says he's better today, that last night he couldn't hardly walk at all. He's very wobbly on his feet and falls easily. He looks so sad but that could be because of the way I've been. To top it off, yesterday was dad's birthday. Just not a good time right now. Thanks so much for your concern. I love Duke more than my own life.
