Hmm, you bring up an interesting point. Are dogs' lives worth less than cows'? We have an entire industry based on slaughtering various farm animals in this country. I think stopping the spread of a disease is a much more justified reason to slaughter a whole bunch of animals than making it so people can buy hamburgers at McDonald's, and the number of slaughtered animals in this case is far, far less than what the American meat industry slaughters in a single day.

So what is it? Is it that these domesticated wolves we've got are cuter and friendlier to us?
