Inverse Effort

Is it just me, or do dogs chew small pieces of food much more than they do larger ones? I mean, If I toss one of our dogs a big, honking piece of meat, it's gone in one gulp. If I toss them the corner of a cracker, it's "chew-chew-chew-chew-chew..." and eventually swallowed. Size aside, you'd think if they were going to linger over a piece of food, it would be the tasty meat rather than the relatively bland cracker-fragment.

I don't get dogs. =)
