Dogs lick pretty much anything and Loki is no exception. In particular, he really loves to lick Yun's chin. I'm not exactly sure why, but I think it's because of the stubble. I tell Yun that his chin is just Loki's tongue cleaner. Here's a picture of some toe licking. Yummy! And ticklish too!
He's starting to become more curious and starting to explore more. Before, he was much more timid and had certain comfort zones. There were places (like the dining area, kitchen, and den) that were impossible to lure him into, even with real yummy treats like chicken. But today, he sniffed the entire dining area... I'm sure he found some yummy smells on the carpet there. And he even put his first paw into the kitchen. So is it a good thing or a bad one that he is now starting to explore more and be less timid?
