Well, I'll agree with you that the innocent suffer in both instances, Brian, but I still say that the wanton cruelty that people like Vick (allegedly) perpetrate on the innocent, even if those innocents don't happen to be human, is just a little more sick. And this same goes for children who have little say in this world also, of course.
If I would die today riding my M/C or driving my car or truck, I made the conscious decision beforehand to risk my life out there on the streets that I know contain a percentage of impaired people who shouldn't be out there on the same roads as me. This doesn't absolve them of their responsiblity to drive sober, but I know they're out there.
My two dogs rely on me to make decisions and to treat them well.
This may be more a case of apple/oranges though, but I didn't bring up this comparsion about the relative morality of these situations.
