I've wondered if Lefty really loves me. He's been taken to the shelter so many times, and I haven't had him for even a year yet, so he may not allow himself to "fall in love" easily. (Admittedly, I could be anthropomorphizing here.)

I also think he loves attention and has figured out that being cute and affectionate himself will get him that attention.

On the other hand, he follows me all over and genuinely seems to prefer being near me.

But then again, maybe I shouldn't wonder too much about this, and let the dog simply be a dog.
