"How do you know that the Aussie Smile means that your dog is happy," you ask?
"Because I've never seen 'the smile' when I'm headed out the door without him in the morning, but it's always there when I return home in the evening."
When they're really smiling, there lip curls up like they've just had a taste of something really sour. It's a beautiful sight. Difficult to capture on 'film', though, as the lip curl only lasts for a few seconds. I'll keep trying. :)
Here's to a zillion more Aussie Smiles! The World can always use a few more...
I'm just saying.
