From not-so-sudden bouts of naughtiness to tips for safe pet travel, my dog Lulu inspires most of my columns. Her fun, frisky outlook on life inevitably colors my own. It's hard to be mad at that face, even when it has destroyed shoes, leather-bound books and countless dog beds. Thanks to Lulu, I take more time to enjoy the little things in life, such as cuddle time or endless shades of blue on display during our morning walks. Pets can teach us so many things, but only if we pay attention.
