Animals

Is there a morally relevant difference between hunting and dogfighting, such that only the latter is wrong? If there is no morally relevant difference between these activities, then either both are right or both are wrong. Which is it?

Addendum: Let me put it formally. The following propositions are inconsistent:

1. Hunting is morally acceptable.
2. Dogfighting is morally unacceptable.
3. There is no morally relevant difference between hunting and dogfighting.

Everyone must reject at least one of these propositions. Which do you reject?
